In the above configuration, the first musical score image that displays a plurality of musical note images representing each musical note constituting the musical composition on the time axis and the pitch axis, and the position of each musical note image on the time axis are maintained. The second musical score image in which a plurality of musical note graphic images of the first musical score image are arranged linearly along the time axis is selectively displayed. Therefore, in the first musical score image, the user can confirm in detail the content of each musical note including the pitch of each musical note, while in the second musical score image, a plurality of musical note graphic images are linear in the direction of the time axis. Therefore, there is an advantage that the area required for displaying each note of the target music is reduced as compared with the first musical score image. The first score image and the second score image are “selectively displayed” means that any one of a plurality of images including the first score image and the second score image is displayed on the display device. This is not limited to a configuration in which the first score image and the second score image are alternatively displayed.

  In a preferred aspect of the present invention, the display control means causes the display device to display a lyrics-edited image for the user to instruct the voice code of each note constituting the music together with the second score image. In the above configuration, the lyrics edited image for the user to specify the voice code of each note is displayed on the display device together with the second score image. According to the present invention, since the area required for displaying the second musical score image is reduced, there is an advantage that it is easy to secure the display area of the lyrics edited image.

  In a preferred aspect of the present invention, the display control means includes a first lyrics-edited image (for example, the lyrics-edited image 84) that allows the user to specify the audio code of each note constituting the song, and a plurality of notes constituting the song. The second lyric edit image (for example, the lyric edit image 86) that can be selected by the user from a plurality of candidate words is selectively displayed as a lyric edit image on the display device. In the above aspect, the first lyric edit image in which the user can specify the audio code of each note and the second lyric edit image in which the user can select the audio code of each note from a plurality of candidate words are selectively used. Is displayed. Therefore, in the first lyric edited image, a voice code that sufficiently reflects the user's intention and preference can be set by designating the voice code by the user. In the second lyric edited image, each note is selected by selecting a candidate word. There is an advantage that the voice code can be easily set.

  The music display device according to a preferred aspect of the present invention comprises an instruction receiving means for accepting selection of one or more musical note images by a user, and the display control means allows the instruction receiving means to select one musical note image. When accepted, the first lyrics edited image is displayed, and when the instruction receiving means accepts selection of a plurality of musical note graphic images, the second lyrics edited image is displayed. In the above aspect, since the first lyric edited image and the second lyric edited image are switched according to the number of note images selected by the user, the workload of the user to edit the voice code of each note is reduced. There is an advantage of being.

  In a more preferred aspect, the display control means includes a plurality of candidates composed of a number of segment units (for example, characters and syllables) corresponding to the number of musical note images received by the instruction receiving means in the second lyrics edited image. The word is displayed on the display device as a candidate for selection by the user. In the above aspect, since a plurality of candidate words composed of the same number of characters as the number of note images selected by the user are displayed in the second lyric editing image, the desired number of notes of the music is sounded. There is an advantage that the workload of the user who tries to assign the code is reduced.

  The sound processing apparatus according to each of the above aspects is realized by hardware (electronic circuit) such as a DSP (Digital Signal Processor) dedicated to processing of an acoustic signal, or a general-purpose operation such as a CPU (Central Processing Unit). This is also realized by cooperation between the processing device and the program.

  FIG. 5 is a flowchart of the operation of the sound processing apparatus 100 (arithmetic processing apparatus 12). For example, when the user instructs activation of the sound processing program PGM by an operation on the input device 24, the processing of FIG. 5 is started. When the sound processing program PGM is activated, the arithmetic processing unit 12 (instruction receiving unit 32) determines whether or not an instruction from the user has been received (SA1). When an instruction from the user is accepted (SA1: YES), the arithmetic processing unit 12 (display control unit 34) updates the display image of the display device 22 according to the content of the instruction from the user (SA2). Further, the arithmetic processing unit 12 (information management unit 36) updates the music data M and the series data DS in the storage device 14 in accordance with an instruction from the user (SA3). If the user's instruction has not been accepted (SA1: NO), the processing of step SA2 and step SA3 is not executed.

  The arithmetic processing unit 12 (instruction receiving unit 32) determines whether or not an instruction to generate the acoustic signal S has been received from the user (SA4). When an instruction to generate the acoustic signal S is received (SA4: YES), the arithmetic processing unit 12 (signal processing unit 38) performs the accompaniment sound data QB and sound of the music data M and the material data Q stored in the storage device 14. An acoustic signal S of the singing sound of the target music is generated using the segment data QC (SA5). When the instruction for generating the acoustic signal S is not received (SA4: NO), the generation of the acoustic signal S (SA5) is not executed. The arithmetic processing unit 12 (instruction receiving unit 32) determines whether or not the user has instructed the end of the sound processing program PGM (SA6). When the termination instruction has not been received (SA6: NO), the arithmetic processing unit 12 shifts the processing to step SA1 and repeats the above-described processing. On the other hand, when an end instruction is received from the user (SA6: YES), the arithmetic processing unit 12 ends the sound processing program PGM.

  FIG. 6 is a schematic diagram of an image displayed on the display device 22 by the display control unit 34. When the sound processing program PGM is activated, the display control unit 34 causes the display device 22 to display the initial image 40 of FIG. The initial image 40 is a screen that allows the user to select one of a plurality of material data Q (themes) stored in the storage device 14, and more specifically, a list image in which display names of the plurality of material data Q are arranged. It is. The user can select desired material data Q among the plurality of material data Q presented in the initial image 40 by appropriately operating the input device 24.

  When the instruction receiving unit 32 receives an instruction to select the material data Q by the user (that is, selection of the theme of the target music), the display control unit 34 edits the edited image 50 in FIG. 6 for the user to edit the target music. Is displayed on the display device 22. The edited image 50 is a screen for the user to select a phrase for each block B on the time axis and configure a target music piece, and includes a score image 52 and a selected image 54.

  The selected image 54 is a screen on which a plurality of phrase images G represented by each image data QA3 in the material data Q selected by the user in the initial image 40 are arranged. Specifically, the display control unit 34 selects one block B on the time axis (hereinafter referred to as “target block B”), and a plurality of unit data U included in the music edit data QA of the material data Q. Among them, a plurality of phrase images G indicated by the image data QA3 of each unit data U belonging to the target block B are arranged. The condition for selecting the target block B is arbitrary. For example, immediately after the editing of the target music is started, the first block B is selected as the target block B, and the phrase of one target block B is confirmed. A configuration in which the immediately following block B is selected as the target block B is suitable. It is also possible for the user to select the target block B by operating the input device 24.

  As described above, the contents and combinations of phrases that are selection candidates for each block B are different for each block B. Therefore, the plurality of phrase images G to be displayed in the selected image 54 are different for each block B. For example, focusing on different arbitrary blocks Ba (first block) and block Bb (second block), a plurality of phrase images G (a plurality of phrases to be selected by the user) displayed on the selection image 54 are: The block Ba and the block Bb are different. Further, as illustrated in FIG. 6, the display control unit 34 arranges the display names (phrase A1, phrase A2,...) Specified by the related data QA1 in the vicinity of each phrase image G. In response to a user operation on the selected image 54 (for example, a drag operation or swipe operation on the operation surface), the display control unit 34 scrolls the arrangement of the plurality of phrase images G in the horizontal direction.

  The user can select the phrase image G of one desired phrase among the plurality of phrase images G of the selection image 54 by appropriately operating the input device 24. The instruction receiving unit 32 receives an instruction for selecting a phrase image G (selecting a phrase to be assigned to the target block B) by the user. The display control unit 34 sets the phrase image G to a temporary selection state when the instruction receiving unit 32 receives an operation (for example, a tap operation) on a specific phrase image G on the operation surface of the input device 24. As illustrated in the edited image 50 of FIG. 6, the phrase image G in the selected state (one phrase image G at the left end in the illustration of FIG. 6) and the non-selected phrase image G are different (for example, selected state). The phrase image G is displayed with the frame line highlighted. When one phrase image G transitions to the selected state, the signal processing unit 38 supplies the reproduction data QA4 of the phrase selected by the user to the sound emitting device 26 to reproduce the phrase. Therefore, the user can select a desired phrase image G from the selected image 54 while actually listening to the reproduced sound of the phrase corresponding to each phrase image G and confirming the content. In the above example, the reproduction data QA4 prepared in advance is illustrated. However, the signal processing unit 38 uses the melody data QA2 and the speech element data QC to generate the phrase acoustic signal S. Is preferably generated and supplied to the sound emitting device 26 (therefore, the reproduction data QA4 is omitted).

  When the instruction receiving unit 32 receives an operation (for example, a tap operation) on the phrase image G in the selected state, the selection of the phrase image G is confirmed. When the selection of the phrase image G is confirmed, the information management unit 36 adds the identification code of the phrase corresponding to the phrase image G to the series data DS. Therefore, at the stage where the phrase selection described above is repeated over a plurality of blocks B on the time axis, the time series of the plurality of phrases selected for each block B is designated by the series data DS.

  The musical score image 52 of the edited image 50 in FIG. 6 is an image that presents the phrase of one phrase image G in the selected state in the selected image 54 to the user. Specifically, the score image 52 represents each note specified by the melody data QA2 of the phrase selected by the user (the melody data QA2 in the same unit data U as the image data QA3 of the phrase image G in the selected state). This is a piano roll type image in which a musical note image Z to be placed is arranged in a region where a time axis and a pitch axis intersecting each other are set. That is, the position on the pitch axis of the note image Z of each note is set according to the pitch X1 specified by the melody data QA2 for the note, and the position and display length of the note image Z on the time axis are determined by the melody. The data QA2 is set according to the sound generation period X2 designated for the note. Further, the phonetic image X3 that the melody data QA2 designates the note is added to the note image Z of each note. Specifically, the voice code X3 is arranged inside the musical note image Z. It is also possible to arrange the voice code X3 in the vicinity (outside) of the musical note graphic image Z.

  As can be understood from FIG. 6, the musical score image 52 is generally in a relationship in which one phrase image G selected by the user in the selected image 54 is enlarged. Therefore, the user selects a desired phrase while comparing a plurality of phrases by visually recognizing each phrase image G in the selected image 54, and by visually recognizing the score image 52, the detailed contents of the selected phrase. It is possible to confirm. The display control unit 34 scrolls the arrangement of the plurality of musical note graphic images Z and changes the display magnification in response to an instruction from the user with respect to the score image 52. Therefore, the range on the pitch axis and the time axis to be displayed in the musical score image 52 in each phrase is changed according to an instruction from the user.

  When a phrase is selected for each of a desired number of blocks on the time axis, the user operates the operation graphic image 56 of the edited image 50. When the instruction receiving unit 32 receives an operation (an instruction to end phrase selection) on the operation icon 56, the display control unit 34 individually selects each note of each phrase selected in the edited image 50 in accordance with an instruction from the user. The edited image 60 for editing is displayed on the display device 22, and the information management unit 36 generates music data M corresponding to the phrase for each block B and stores it in the storage device 14. Specifically, as illustrated in FIG. 7, the information management unit 36 designates the series data DS for each block B among the plurality of melody data QA2 in the material data Q selected by the user in the initial image 40. The music data M is generated by arranging the melody data QA2 of each phrase to be performed in time series in the order of the block B. That is, the music data M designates a target music in which a plurality of phrases selected by the user are arranged in time series.

  The edited image 60 in FIG. 6 includes a score image 62 and an operation image 64. The musical score image 62 is a piano roll type image in which a musical note image Z representing each musical note designated by the music data M is arranged in a region in which a time axis and a pitch axis are set. Similar to the score image 52 of the edited image 50, the position of the note image Z of each note in the direction of the pitch axis is set according to the pitch X1 specified by the music data M for the note, and in the direction of the time axis. The position and display length of the note image Z of each note are set according to the sound generation period X2 specified by the music data M for the note. Further, a sound code X3 designated by the music data M as the note is added to the note image Z of each note. Specifically, the voice code X3 is arranged inside the musical note image Z. The display control unit 34 scrolls the arrangement of the plurality of musical note graphic images Z and changes the display magnification according to an instruction from the user with respect to the score image 62. That is, the range on the pitch axis and the time axis to be displayed in the musical score image 62 among the phrases of the target music is changed according to an instruction from the user.

  The user can arbitrarily select one or more note graphic images Z in the score image 62 by appropriately operating the input device 24. Specifically, the user can select any one musical note graphic image Z by one tap operation on the operation surface. Further, the user selects a plurality of note graphic images Z by executing a drag operation on the operation surface so as to trace a desired series of musical note graphic images Z as shown by chain arrows in FIG. It is possible. The instruction receiving unit 32 receives the selection of the musical note image Z by the user. The signal processing unit 38 generates a sound signal S of a note corresponding to the note image Z selected by the user and supplies it to the sound emitting device 26. Specifically, the signal processing unit 38 generates the acoustic signal S by adjusting the speech unit corresponding to the speech code X3 of the note corresponding to the note image Z selected by the user to the pitch X1 of the note. To do. Therefore, every time one musical note image Z in the musical score image 62 is selected, the singing sound of the musical note corresponding to the musical note image Z is sequentially reproduced.

  FIG. 9 is an explanatory diagram of processing executed when the instruction receiving unit 32 receives selection of the musical note iconic image Z in the score image 62. The display control unit 34 determines whether or not the number of the musical note graphic images Z received by the instruction receiving unit 32 is 1 (SB1). When the instruction accepting unit 32 accepts selection of one musical note image Z (SB1: YES), the display control unit 34 changes the display image by the display device 22 from the edited image 60 to the edited image 81, and accepts the instruction. When the unit 32 accepts selection of a plurality of musical note graphic images Z (SB1: NO), the display image is changed from the edited image 60 to the edited image 82. On the other hand, when the user gives an instruction to cancel the selection of each musical note image Z, the display control unit 34 changes the display image from the edited image 81 or the edited image 82 to the edited image 60.

  The edited image 81 in FIG. 9 includes a score image 80 and a lyrics edited image 84, and the edited image 82 includes a score image 80 and a lyrics edited image 86. The musical score image 80 of each of the edited image 81 and the edited image 82 includes a plurality of musical note image images Z displayed in the musical score image 62 of the edited image 60 (or the musical score image 52 of the edited image 50) in the time axis direction. This is an image arranged in a straight line along the time axis (on the reference line L0 parallel to the time axis) while maintaining the position and display length of each musical note image Z.

  That is, in the score image 62 before the selection of the note image Z, the time series of each note image Z is displayed in two dimensions of the time axis and the pitch axis, but in the score image 80 after the selection of the note image Z, the pitch is displayed. Each note graphic image Z is displayed in a one-dimensional manner in which the axis is omitted (that is, the difference in pitch of each note is ignored). In other words, the distribution range in the vertical direction of the plurality of musical note graphic images Z is reduced in the score image 80 as compared with the score image 62. Accordingly, the size LB1 in the vertical direction of the score image 80 is smaller than the size LA1 in the vertical direction of the score image 62. In other words, the vertical size of the image is reduced by changing the score image 62 to the score image 80 (LA1 → LB1). When the edited image 60 is changed to the edited image 81 or the edited image 82, each musical note image Z is moved from the position on the pitch axis of each musical note image Z in the musical score image 62 to the position on the reference line L0 in the musical score image 80. It is also possible to display a moving image (animation) showing a state of continuous movement. As illustrated in FIG. 9, the sound code X 3 is added to each note image Z in the score image 80 in the same manner as the score image 52 and the score image 62. Further, each note image Z selected by the user among the plurality of note images Z in the score image 80 is highlighted.

  The lyrics edited image 84 of the edited image 81 and the lyrics edited image 86 of the edited image 82 are images for the user to edit the lyrics of each note, and the score image from the score image 62 in the display area of the display device 22. It is arranged in the area secured by the reduction of the image by the change to 80 (the area below the score image 62). Accordingly, the vertical size LB2 of each of the lyrics edited image 84 and the lyrics edited image 86 is larger than the vertical size LA2 of the operation image 64 of the edited image 60. In each of the edited image 81 and the edited image 82, the vertical size LB1 of the score image 80 is smaller than the vertical size LB2 of the lyrics edited image 84 and the lyrics edited image 86.

  When the user selects one note image Z (SB1: YES), the lyric edit image 84 is a screen for the user to arbitrarily specify the lyrics of each note one character at a time. Specifically, the lyrics edited image 84 includes a plurality of operation icons 842 for the user to arbitrarily designate one character. The display control unit 34 causes the area 844 to display each character that is sequentially designated by the user by operating each operation icon 842. When the instruction accepting unit 32 accepts the operation of the operation icon 846 for instructing the confirmation of the character, the voice code X3 of the note of each note image Z in the score image 80 is changed to each character in the area 844. . For example, when the user designates n characters in the operation on the lyrics edited image 84, the n characters designated by the user for each of the n notes starting from the note of one note image Z in the selected state. Are assigned in turn. Specifically, the display control unit 34 specifies each voice code X3 (for example, initial character “ra” specified by the melody data QA2) of each musical note image Z in the musical score image 80 of the edited image 81. The information management unit 36 changes the voice code X3 of each note of the music data M to the character designated by the user.

  In addition, the user appropriately operates the input device 24 to thereby select a plurality of musical notes starting with one musical note graphic image Z selected in the musical score image Z in the musical score image 80 of the edited image 81. The image Z can be selected. That is, the number of musical note graphic images Z in the selected state is changed from single to plural. When the instruction accepting unit 32 accepts selection of a plurality of musical note graphic images Z (change in the number of musical note graphic images Z) while the edited image 81 is displayed, the display control unit 34 edits the display image by the display device 22. The image 81 is changed to the edited image 82.

  The lyrics-edited image 86 displayed when selecting a plurality (m) of note images Z (SB1: NO) is a screen for the user to select one of a plurality of candidate words WC prepared in advance. is there. Specifically, the lyrics edited image 86 of the first embodiment includes a candidate list 862. The display control unit 34 acquires candidate word data QD in the material data Q selected by the user in the initial image 40 from the storage device 14, and selects a plurality of candidate words WC designated by the candidate word data QD by the user. Are arranged in the candidate list 862. The display control unit 34 of the first embodiment extracts candidate words WC having the same number of characters n as the number m of selected musical note images Z from among the plurality of candidate words WC designated by the candidate word data QD, and arranges them in the candidate list 862. To do. For example, in the state where three (m = 3) musical note images Z are selected as illustrated in FIG. 9, a plurality of candidate words WC composed of three letters (n = m = 3) are extracted as selection candidates. And displayed in the candidate list 862.

  When the instruction accepting unit 32 accepts an operation of the operation image 864 instructing the confirmation of the selection of the candidate word WC in the candidate list 862, the sound code of each note of the m note images Z selected in the score image 80 X3 is changed to each character of the candidate word WC selected by the user. That is, n (n = m) characters of the candidate word WC selected by the user are sequentially assigned to each of the m musical note images Z in the selected state. Specifically, the display control unit 34 selects the phonetic code X3 (for example, the initial character “ra” specified by the melody data QA2) of each note image Z in the score image 80 of the edited image 82 by the user. The information management unit 36 changes the voice code X3 of each note of the music data M to each character of the candidate word WC selected by the user. As understood from the above description, in each musical score image 80 of the edited image 81 and the edited image 82, the voice code X3 of each note graphic image Z is also arranged linearly in the direction of the time axis. Therefore, there is an advantage that the user can easily confirm the lyrics (time series of the voice code X3) as compared with the score image 62 in which the voice code X3 of each note image Z is distributed over a wide range on the pitch axis.

  The user can select an arbitrary musical note graphic image Z in the musical score image 80 of the edited image 81 or the edited image 82 by appropriately operating the input device 24. The signal processing unit 38 generates a sound signal S of a note corresponding to the note image Z selected by the user in the score image 80 and supplies it to the sound emitting device 26. Specifically, the signal processing unit 38 selects the speech unit corresponding to the speech code X3 of the note corresponding to the note image Z selected by the user in the same manner as when the note image Z in the score image 62 is selected. The acoustic signal S is generated by adjusting to the pitch X1 of the note. Therefore, every time one musical note image Z in the musical score image 62 is selected, the singing sound of the musical note corresponding to the musical note image Z is sequentially reproduced. As understood from the above description, the pitch X1 of each note is omitted from the score image 80 (therefore, the pitch of each note cannot be confirmed from the score image 80 alone). By listening to the sound reproduced by selecting the note image Z, the user can audibly confirm the pitch of an arbitrary note.

  When the instruction accepting unit 32 accepts the operation of the operation icon 802 for instructing the end of lyrics editing in the edited image 81 or the edited image 82, the display control unit 34 displays the display image on the display device 22 from the edited image 81 or the edited image 82. The edit image 60 is changed. That is, in the musical score image 80 of the edited image 81 and the edited image 82, a plurality of note graphic images Z arranged in a straight line along the time axis are changed to the edited image 60, and the sound corresponding to the pitch X1 of each note is changed. Move to a position on the high axis. When the edited image 81 or the edited image 82 is changed to the edited image 60, each musical note image Z is continuously displayed from the reference line L0 in the musical score image 80 to the position on the pitch axis of each musical note image Z in the musical score image 62. It is also possible to display a moving image showing a state of moving.

  As illustrated in FIG. 9, the operation image 64 of the edited image 60 includes a plurality of operation graphic images (642, 644, 646, 648) that receive an operation from the user. When the instruction accepting unit 32 accepts an operation of the operation icon 642 instructing the reproduction of the acoustic signal S, the signal processing unit 38 generates the acoustic signal S corresponding to the current music data M and supplies it to the sound emitting device 26. . That is, the singing sound of the target music is reproduced. Therefore, the user can edit the lyrics by moving to the edited image 81 or the edited image 82 at any time while actually listening to the target music and confirming the melody and lyrics. The display control unit 34 scrolls the time series of each note graphic image Z in the score image 62 in the direction of the time axis so as to be interlocked with the progress of the reproduction of the target music. When the instruction accepting unit 32 accepts an operation on the operation icon 644, the display control unit 34 changes the display range of the score image 62 to the top of the target music piece, and the instruction accepting unit 32 accepts an operation on the operation icon 646. The display range of the score image 62 is changed to the end of the target music.

  When the instruction accepting unit 32 accepts an operation on the operation image 648 of the operation image 64, the display control unit 34 changes the display image on the display device 22 from the edited image 60 to the edited image 70 as illustrated in FIG. In the musical score image 52 of the edited image 50 and the musical score image 62 of the edited image 60, some notes of the target music are displayed, whereas the edited image 70 uses the time series of a plurality of phrases over the entire target music. Is a screen to confirm.

  As illustrated in FIG. 6, in the edited image 70, a plurality of phrase images G selected by the user in the edited image 50 are displayed in time series. Specifically, a plurality of phrase images G are arranged over a plurality of rows. That is, the phrase image G immediately after the phrase image G at the end of each line is arranged at the head of the next line. The display control unit 34 generates and displays the edited image 70 by arranging the phrase image data QA3 corresponding to the identification information specified by the series data DS in the storage device 14 in the order specified by the series data DS. It is displayed on the device 22. In addition, the display control unit 34 arranges the display name (phrase A1 or the like) of the phrase designated by the related data QA1 in the vicinity of each phrase image G.

  The user can select one desired phrase image G among the plurality of phrase images G of the edited image 70 by appropriately operating the input device 24. The instruction receiving unit 32 receives the selection of the phrase image G by the user. The display control unit 34 sets the phrase image G to the selected state when the instruction receiving unit 32 receives an operation (for example, a tap operation) on a specific phrase image G on the operation surface of the input device 24. As illustrated in the edited image 70 of FIG. 6, the display control unit 34 distinguishes between the phrase image G in the selected state and the non-selected phrase image G (for example, highlights the frame line of the selected phrase image G). The operation graphic image 72 is arranged in the vicinity of the selected phrase graphic image G.

  When one phrase image G is set to the selected state, the signal processing unit 38 generates an acoustic signal S of a phrase corresponding to the phrase image G and supplies it to the sound emitting device 26. Specifically, the sound signal S is obtained by adjusting and connecting the speech unit of the speech unit data QC with reference to the section corresponding to the selected phrase in the music data M and mixing the accompaniment sound data QB. Generate. When the instruction receiving unit 32 receives an operation (for example, a tap operation) on the selected phrase image G, the display control unit 34 changes the display image displayed on the display device 22 from the edited image 70 to the edited image 60, A phrase corresponding to the phrase image G in the selected state is displayed on the score image 62. Accordingly, the user can check the desired composition and edit the lyrics by moving to the edited image 60 at any time while confirming the entire composition of the target music (phrase time series) with the edited image 70. Is possible.

  The user can operate the operation iconic image 72 using the input device 24. The operation iconic image 72 is an image for instructing a change (replacement) of a phrase in a selected state. When the instruction accepting unit 32 accepts an operation on the operation iconic image 72, the display control unit 34 changes the display image displayed on the display device 22 from the edited image 70 to the edited image 50, and the phrase corresponding to the phrase image G in the selected state. Is displayed on the score image 52. Then, when the instruction receiving unit 32 accepts the selection of an arbitrary phrase image G of the selected image 54, the phrase of the one phrase image G selected in the edited image 70 among the target music is the selected image 54. It is replaced with the phrase of the selected phrase image G. Specifically, the information management unit 36 changes the section corresponding to the phrase selected in the edited image 70 in the music data M to the melody data QA2 of the phrase selected in the selected image 54, and converts it into the series data DS. Reflect phrase changes. Therefore, the user can move to the edited image 50 at any time while confirming the entire configuration of the target music with the edited image 70, and can confirm each note of a phrase and change the phrase. . In addition, although the change of a phrase was illustrated in the above illustration, it is also possible to insert an arbitrary frame selected by the user between two adjacent frames.

  As illustrated in FIG. 6, the display control unit 34 arranges the operation iconic image 74 immediately after the phrase image G of the last phrase of the target music in the edited image 70. The operation iconic image 74 is an image for instructing addition of a phrase to the end of the target musical piece at the current stage. When the instruction accepting unit 32 accepts an operation for the operation iconic image 74, the display control unit 34 changes the display image displayed on the display device 22 from the edited image 70 to the edited image 50. And when the instruction | indication reception part 32 receives selection of the arbitrary one phrase images G in the selection image 54, the phrase corresponding to the said phrase image G will be added to the end of the object music. Specifically, the information management unit 36 adds the melody data QA2 of the phrase selected in the selection image 54 to the end of the music data M, and adds the identification code of the phrase to the sequence data DS. An upper limit is set for the total number of blocks constituting the target music, and the operation icon 74 is not displayed when the total number of phrases selected by the user reaches the upper limit number of blocks (addition of additional phrases is prohibited) Configuration) can also be employed.

  The user can operate the operation iconic image 76 (trash can) of the edited image 70 using the input device 24. The operation iconic image 76 is an image for instructing deletion of a phrase.

<Modification>
Each of the above forms can be variously modified. Specific modifications are exemplified below. Two or more modes arbitrarily selected from the following examples can be appropriately combined.

(1) In each of the above-described embodiments, the phrase display name is arranged in the vicinity of each phrase image G in the selected image 54 or the edited image 70 of the edited image 50, but information displayed together with the phrase image G (hereinafter “ "Phrase information" is not limited to the phrase display name. For example, words such as “starting phrase”, “connecting phrase”, and “ending phrase” (the musical significance of each phrase in the music), the chord progression of each phrase, and the sound set for each note of the phrase A configuration in which the code X3 (lyrics) is displayed in the vicinity of the phrase image G as phrase information may be employed. In each of the above-described embodiments, the phrase information is fixedly displayed in the vicinity of each phrase image G in the selected image 54 or the edited image 70 of the edited image 50. However, the phrase information for the phrase image G in the selected state is displayed. A configuration that temporarily displays (pop-up display) is also employed.

(2) In each of the above-described embodiments, the phrase image G that represents the time series of musical notes over one phrase is illustrated (FIG. 4), but the content of the phrase image G is not limited to the above examples. For example, it is also possible to display a phrase image G that represents a time series of notes in a specific section (for example, the head portion) of one phrase. In each of the above-described embodiments, a fixed image prepared in advance is used as the phrase image G. However, for example, the phrase image G can be dynamically changed according to the contents of the music data M. Specifically, in the configuration in which the pitch X1 of each note is changed according to an instruction from the user as illustrated in the second embodiment, the change in the pitch X1 of each note is reflected in the phrase image G. The That is, the position on the pitch axis of the note image Z corresponding to each note of the phrase image G is changed according to the pitch X1 of the note.

(3) Image data (hereinafter referred to as “effect image data”) of an image (for example, an image such as an animation character) used for displaying an edited image can be included in the material data Q. Specifically, in the musical score image 52 of the edited image 50 and the musical score image 62 of the edited image 60, the background image of each musical note graphic image Z is designated by effect image data. Further, the background image of the musical note graphic image Z in each phrase image G displayed on the selected image 54 or the edited image 70 of the edited image 50 is designated by effect image data.

(4) In each of the above-described embodiments, the configuration in which a plurality of unit data U corresponding to different phrases is divided into a plurality of blocks B in advance is exemplified, but the unit data U belonging to each block B is dynamically changed. It is also possible to do. Specifically, a configuration is adopted in which a phrase that is a selection candidate of the immediately following block B is changed according to a phrase selected by the user for any one block B. For example, a phrase that can be musically harmonized with a phrase selected by the user for one block is extracted (squeezed) as a selection candidate phrase in the immediately following block. It is also possible to appropriately change the order of arrangement of the plurality of phrase images G in the selected image 54 of the edited image 50. For example, a plurality of phrase images G that are candidates for selection of phrases in the immediately following block are arranged in the selected image 54 in the order corresponding to the degree of musical harmony with respect to the phrase selected by the user for one block.

(5) In the edited image 81 or the edited image 82, the musical note image Z displayed on the musical score image 80 can display (for example, pop-up display) the voice code X3 of the notes before and after each note. For example, as illustrated in FIG. 12, a musical note image Z of three notes corresponding to “Hare” among the lyrics “A certain spread day (on a certain sunny day)” is represented as a score image 80. Assume the situation shown in. The display control unit 34 includes an auxiliary image 88 including the voice code “A” of each note located immediately before the note of the note image Z displayed in the score image 80, and the voice code “HINI” of each note immediately after. And an auxiliary image 88 including “” are displayed in the score image 80. According to the above configuration, there is an advantage that the voice code X3 of each note in the musical score image 80 can be designated while confirming the voice code X3 of the preceding and following notes on each auxiliary image 88. Note that the range of musical notes in which the audio code X3 is displayed in the auxiliary image 88 is arbitrary. For example, a configuration in which the audio code X3 over a predetermined number of front and rear notes is displayed as the auxiliary image 88, or a configuration in which the audio code X3 over the entire target music is displayed in the auxiliary image 88 is employed.

(6) In each of the above embodiments, a plurality of candidate words WC composed of the same number of characters as the selected number m of the musical note images Z are arranged in the candidate list 862. However, the conditions for the candidate words WC arranged in the candidate list 862 are as follows. Is not limited to the above examples. For example, a configuration is adopted in which candidate words WC that are pronounced with intonation similar to the transition of the pitch X1 of each note among the plurality of candidate words WC are preferentially arranged in the candidate list 862. Specifically, the inflection data of the candidate word WC is set in the candidate word data QD for each candidate word WC, and the inflection similar to the transition of the pitch X1 of the note image Z selected in the musical score image 80. The candidate word WC is preferentially arranged in the candidate list 862. It is also possible to preferentially place candidate words WC related to the lyrics before and after each musical note image Z selected by the user in the score image 80 in the candidate list 862. When the sound processing apparatus 100 is realized by an information processing apparatus such as a mobile phone equipped with an input prediction function (predictive conversion function) for predicting a word input by the user from past character input histories, A configuration is also adopted in which words having a high input frequency are arranged in the candidate list 862 as candidate words WC. In each of the above-described embodiments, one candidate word WC having the same number m of selected note image Z and the same number of characters n is extracted and presented to the user. The total number of characters n is the selected number m of note image Z. It is also possible to extract a combination of a plurality of candidate words WC and present them to the user. For example, when the user selects ten musical note images Z, a combination of one candidate word WC of six characters and one candidate word WC of four characters, or two candidate words of three characters A combination of WC and one candidate word WC of 4 characters is presented to the user.

(7) Images arranged in a region secured by arranging a plurality of musical note graphic images Z linearly in the direction of the time axis in the score image 80 are not limited to the lyrics-edited images (84, 86). For example, as illustrated in FIG. 13, instead of the lyrics editing image 84 and the lyrics editing image 86 (or together with the lyrics editing image 84 and the lyrics editing image 86), the variable for the user to edit the control variable XC of each note. The edited image 89 can be displayed on the display device 22 together with the score image 80. The control variable XC is designated for each note in the music data M, and is a variable for controlling a musical expression given to the reproduced sound of the acoustic signal S, for example. Specifically, variables such as sounding intensity (velocity), volume (dynamics), minute change in pitch after sounding (pitch bend), vibrato, timbre (for example, clarity) are suitable as the control variable XC.

  The variable edited image 89 illustrated in FIG. 13 is an image that represents a time change of the control variable XC of each note as a bar graph. When the instruction receiving unit 32 receives an operation from the user for the variable edit image 89, the display control unit 34 updates the variable edit image 89 in accordance with the instruction from the user, and the information management unit 36 receives the instruction from the user. In response to this, the control variable XC of the music data M is updated. In FIG. 13, the time change of the control variable XC is represented by a bar graph, but the time change of the control variable XC can also be represented by a line graph. The lyrics-edited images (84, 86) exemplified in the above-described respective forms and the variable-edited image 89 exemplified in FIG. 13 are for the user to edit the attributes (speech code X3 and control variable XC) of each note of the target music. Images (attribute-edited images).

  As understood from the above examples, the content of the image displayed together with the score image 80 is arbitrary. Further, even if a configuration in which a specific image is displayed together with the score image 80 is not assumed, as long as a configuration in which a plurality of musical note images Z of the score image 62 are arranged linearly along the time axis is adopted, The above-described effect of reducing the area necessary for displaying notes is realized.

(8) The display mode of the edited image 70 is not limited to the above example. Specifically, a configuration is adopted in which the display mode (visually perceptible properties such as color and shape) of each phrase image G is different depending on the state (edited / unedited) of each phrase of the target music. The For example, a configuration in which the display mode of the phrase image G is different between a phrase in which the user has changed the voice code X3 (lyric) of each note among the plurality of phrase images G in the edited image 70 and another phrase is preferable. . In the second embodiment, the phrase image G can be displayed in a different manner for a phrase in which the user has changed the pitch X1 of each note and another phrase.

  When the instruction receiving unit 32 receives a predetermined operation on the edited image 70, the signal processing unit 38 can generate the acoustic signal S of the target music piece. In the above configuration, the display control unit 34 reproduces the sound signal S so that the phrase image G is displayed differently between the phrase being reproduced by the sound signal S and another phrase. Change sequentially as the process progresses.

(9) In each of the above embodiments, the musical score image 80 obtained by reducing the distribution range of each musical note image Z in the direction of the pitch axis as compared with the musical score image 62 is illustrated (FIG. 9). It is also possible to reduce the distribution range of the musical note graphic image Z. For example, as illustrated in FIG. 14, a musical score image 62 in which a plurality of musical note graphic images Z are arranged in a region in which a pitch axis and a time axis are set is assumed. When the instruction receiving unit 32 receives a predetermined operation (instruction to reduce the score image 62) on the input device 24, the display control unit 34 changes the display image on the display device 22 from the score image 62 to the score image 90 of FIG. change.

  In the score image 90, a plurality of note images are moved in the horizontal direction while ignoring the position of each note image Z on the time axis while maintaining the position of each note image Z in the direction of the pitch axis. The lateral distribution range of the musical note graphic image Z is reduced as compared with the musical score image 62. That is, the horizontal size of the image is reduced by changing the score image 62 to the score image 90. In the area 92 secured by the reduction of the image by changing from the score image 62 to the score image 90, for example, various images such as an image for adjusting the acoustic characteristics of the note represented by each note image Z are displayed. Is done. In the musical score image 90, each musical note graphic image Z in the musical score image 62 is moved to a position close to each other ignoring the position on the time axis, and thus a plurality of musical note graphic images Z are distributed over a wide range on the time axis. Compared with the configuration, there is an advantage that the user can collectively select a plurality of musical note graphic images Z belonging to a specific pitch X1 (or a range on the pitch axis). 14 illustrates the musical score image 90 in which the musical note images Z do not overlap in the horizontal direction. For example, as illustrated in FIG. 15, the musical note images Z of a plurality of musical notes having the same pitch X1 are overlapped with each other. It is also possible to display it.

(10) In each of the above-described embodiments, the signal processing unit 38 exemplifies the configuration in which the acoustic signal S is generated by the unit connection type speech synthesis in which a plurality of speech units are connected on the time axis. The generation method is not limited to the above examples. For example, the signal processing unit 38 can generate the acoustic signal S by speech synthesis using a stochastic model such as a hidden Markov model. Therefore, the speech element data QC of the material data Q can be omitted. The generation target by the signal processing unit 38 is not limited to the acoustic signal S of the singing sound. Specifically, it is possible to generate an acoustic signal S of a performance sound obtained by playing the target musical piece with various musical instruments. For example, the signal processing unit 38 generates the acoustic signal S by connecting time waveforms of musical instrument performance sounds on the time axis according to the music data M.

(11) In the above-described embodiments, the synthesis of Japanese speech has been exemplified, but the language of speech to be synthesized is arbitrary and is not limited to Japanese. For example, the above embodiments can be similarly applied to the case of generating speech in an arbitrary language such as English, Spanish, Chinese, or Korean. In each of the above-described embodiments, one character of Japanese lyrics is assigned to one note (note image Z). However, the correspondence between a voice unit (segment unit) and a note is not limited to the above examples. It is changed appropriately according to the system. For example, the English word “September” can be divided into three syllables “Sep-tem-ber” and assigned to three notes. There may be a case where a plurality of syllables are assigned to one note, or a syllable is assigned to a plurality of notes.

  In each of the above-described embodiments, the candidate word WC composed of the same number of characters as the number m of the musical note image Z selected by the user is presented to the user. Is not limited to the number of characters, and may be changed as appropriate according to circumstances such as language system. For example, it is possible to present to the user the candidate word WC composed of the same number of syllables as the selected number m of the musical note image Z. As understood from the above description, the configuration in which the candidate word WC composed of the same number of letters as the selected number m is presented to the user is the number of segment units (typically letters and syllables) corresponding to the selected number m. ) Is comprehensively expressed as a configuration in which the candidate word WC is configured to be presented to the user.
