The basic pitch determining unit 24 determines the basic pitch according to the key checked by the key acquiring unit 22. The pitch changing means 25 changes the pitch by a semitone or one octave based on the relationship between the basic pitch determined by the basic pitch determining means 24 and the pitch of the note to be changed.

FIG. 3 illustrates a screen for creating a melody. A note cell 301 includes a key 300, a note 302, an octave 303, a note name 304, and a point 306. The key 300 and the score 306 may be omitted. The cursor 305 indicates any note cell 301 or immediately after the last note cell 301. To move the cursor 305, the left and right keys 119 and 120 (FIG. 1) are used. The cursor 305 moves to the left when the key 119 is pressed, and moves to the right when the key 120 is pressed. The key 100 (“0”) is used for inputting a rest. The key 100 is called a rest key. Keys 101 to 107 ("1" to "7") are keys corresponding to CDEFGAB stem sounds and are used to input notes. Table 1 shows the correspondence between note keys and stem sounds. The keys 101 to 107 are called note keys.

  The key 300 represents the key specified in the note cells after the note cell 301. Blank if no key is specified. The key 300 displays “X” when the key designation after the note cell is cancelled. The note 302 represents the note value of the note cell. The note 302 is pressed by pressing the keys 110 (“*”) and 111 (“#”) to change the note value into a full note, a half note, a triple half note, a quarter note, a triple quarter note, and an eighth note.・ It can be adjusted in the range of triple eighth note, sixteenth note, triple sixteenth note, thirty-second note. In addition, the note 302 can be selected by the key 109 (“9”) to indicate the presence or absence of the dot 306. The attached point 306 represents that the sound value is multiplied by 1.5. The same note cell 302 can be inserted into the note cell 302 by pressing the key 108 (“8”).

Octave 303 represents the octave designation of the note cell 301. Octaves are expressed by 1, 2, 3,..., N (N is an integer of 2 or more) in order from the lowest octave. N is preferably about 6. A pitch name 304 represents the pitch name of the note cell 301. Table 2 shows a list of pitch names. The pitch names shown in Table 2 can be used. When the pitch name A can be represented by [♭ [♭] | # [#]] X (the brackets can be omitted, and “P | Q” represents P or Q), X is represented by A Called the stem sound. The pitch of the note cell 301 is determined by a combination of a pitch name and an octave.

  In Table 2, the pitch column shows for convenience the pitch to be output based on the note name of the note cell. “#” Means a semitone higher. “<” Means that a pitch one octave lower than the octave of the note cell and “>” means that a pitch one octave higher is output. If none is attached, it means that the pitch is output in the octave of the note cell. The frequency column indicates the frequency of the pitch output based on the note name and octave of the note cell. N included in the frequency formula represents the octave of the note cell. M is a value obtained by rounding down N ÷ 2 to an integer.

FIG. 4 shows an example of the menu screen. When the user presses key input 116 (menu key) on the screen shown in FIG. 3, the portable terminal device displays the menu screen (menu 1) shown in FIG. This menu 1 includes an option “setting / cancellation”. The user selects “tone setting / cancellation” and inputs a key. FIG. 5 shows a key input menu screen (menu 2). Menu 2 includes 30 different keys and key release options. The user can select a key from among these choices using the up / down / left / right keys and the selection key. When the user selects a key, a code indicating that the key has been selected is added to the note cell 301 (FIG. 3) indicated by the current cursor. When the user selects key signature cancellation, a code indicating key signature cancellation is added. Table 3 shows a list of key signatures displayed in the key 300 when the user selects a key.

  FIG. 6 shows an operation procedure. The control unit 10 (FIG. 2) determines whether or not the melody creation function is called from the overall functions of the mobile terminal device (step A1). When the melody creation function is not called, another process is performed (step A2). When the melody creation function is called, the control unit 10 copies data from the melody memory 14 to the memory unit 13 and starts a melody editing process. Thereafter, the control unit 10 performs melody editing on the memory unit 13. When a melody is newly created, data copy from the melody memory 14 to the memory unit 13 is not necessary.

  The control unit 10 performs a note input process (step A3). Details of this processing will be described later. The control unit 10 determines whether or not a key is specified in the menu 2 (FIG. 5) (step A4). When the key is specified, the control unit 10 adds a code indicating that the key is specified to the note cell indicated by the cursor by the key specifying means 21 (step A5). Then, it returns to step A3 and continues note input. The control unit 10 determines whether or not the key has been canceled (step A6). When the key is released, the control unit 10 uses the key designating unit 21 to add a code indicating the key release to the note cell indicated by the cursor (step A7). Then, it returns to step A3 and continues note input.

  After inputting the note, the control unit 10 determines whether “Register Melody”, “Discard Current Editing”, or the like is selected from the menu 1 (FIG. 4) (step A8). When “register melody” is selected, the control unit 10 stores the melody edited on the memory unit 13 in the melody memory unit 14 and ends the melody creation (step A10). When “Discard Current Editing” is selected, the control unit 10 discards the data edited on the memory unit 13 and ends the melody creation. When “other than melody registration” or “discard current edit” is selected, for example, when “tempo setting” or the like is selected, the control unit 10 performs a process corresponding to that (step A9), and proceeds to step A3. Go back and continue entering notes.

  FIG. 7 shows the procedure of the note input process. An “insert mode” is introduced when inputting notes. “Insert mode” is a variable introduced to control the behavior when the note value keys (109 to 111) and the up and down keys (118, 121) are pressed, and has a value of ON or OFF. First, the control unit 10 sets the “insertion mode” to OFF (step B1). The control unit 10 acquires key input information using the key input unit 12 (step B2).

  The control unit 10 determines whether or not the left and right keys (119, 120) are pressed (step B3). When the left / right key is pressed, the control unit 10 moves the cursor according to the pressed key (step B4). Further, the control unit 10 sets the “insertion mode” to OFF, returns to step B2, and continues to acquire key input information. The control unit 10 determines whether or not the sound value key (109 to 111) has been pressed (step B5). When the note value key is pressed, the control unit 10 changes the note value of the note at the following position (step B6). That is, when the cursor position is at the end (there is no note cell) or the insertion mode is ON, the note value immediately before the cursor position is changed. Otherwise, the note value at the cursor position is changed.

  The controller 10 determines whether or not the up / down key (118, 121) has been pressed (step B7). When the up / down key is pressed, the control unit 10 performs a pitch changing process by the pitch changing means 25 (step B8). When the control unit 10 finishes the pitch changing process, the control unit 10 returns to Step B2 and continues the note input.

  FIG. 8 shows the procedure of the pitch change process. The pitch changing means 25 first determines the position L of the note cell whose pitch is to be changed (step C1). When the cursor position is at the end or the insertion mode is ON, the pitch change means 25 sets the position immediately before the cursor position as the position L of the note cell whose pitch is to be changed. In other cases, the pitch changing means 25 sets the cursor position to the position L of the note cell whose pitch is to be changed.

  The pitch change means 25 acquires the key of the current cursor position by the key acquisition means 22 (step C2). The key acquisition unit 22 acquires the key of the current cursor position in the following procedure. In other words, the key acquisition means 22 is a note cell to which a chord indicating that a key has been selected or a note cell to which a chord indicating cancellation of key is added in the forward direction from the current cursor position. Search for. When the note cell to which the chord indicating that the key is selected is found, the key acquisition unit 22 sets the key selected in the note cell as the key at the current cursor position. When the note cell to which the chord indicating the key release is added is searched or when there is no note cell to which the chord indicating the key selection is added before the first note cell, the key acquiring unit 22 The key at the cursor position is “no key”.

  The pitch changing means 25 passes the key of the note cell at the current cursor position acquired in step C2 to the basic pitch determining means 24 and requests the determination of the basic pitch. The basic pitch determining means 24 determines whether or not a key is designated at the current cursor position (step C3). When the key is designated, the basic pitch determining means 24 determines the basic pitch S at the position L based on the set key and the pitch of the note cell at the position L (step C5).

In step C5, the basic pitch determining means 24 determines the basic pitch using the correspondence between the key and the corresponding pitch name. Table 4 shows the correspondence between the key and the corresponding note names. In step C5, in Table 2, the stem sound of the note cell at position L is R, and in Table 4, the same stem sound among the elements of the set of note names that can be given keys is A , The pitch with the same octave pitch name as the note cell at position L and the pitch name as A is determined as the basic pitch S. For example, if the key of the note cell at position L is “F major”, the pitch name is “B”, and the octave is “4”, the basic pitch S is changed to the pitch name “♭ B”, the octave “4”. "

  If the key is not designated at the current cursor position, the basic pitch determining means 24 determines the basic pitch S based on the pitch of the note cell at the position L (step C4). In step C4, the same pitch as the basic pitch when C major is specified is set as the basic pitch S. For example, when the pitch of the note cell at position L is “#C”, the basic pitch S is “C”, and when the pitch is “♭ E”, the basic pitch S is “E”.

  The pitch changing means 25 compares the pitch of the note cell at position L with the basic pitch S determined in step C4 or step C5 (step C6). When the pitch of the note cell at the position L is lower than the basic pitch S, the pitch changing means 25 determines the type of the pressed key (step C7), and when the up key is pressed, the position is changed. The pitch of the L note cell is set to the basic pitch S (step C10). For example, when the pitch of the note cell at position L is “♭ E” and the basic pitch S is “E”, the pitch of the note cell at position L is raised by half a tone to “E”. When the pitch of the note cell at the position L is lower than the basic pitch S and the down key is pressed, the pitch changing means 25 changes the pitch of the note cell at the position L to the basic pitch S. 1 octave below (step C14).

  When it is determined in step C6 that the pitch of the note cell at position L is higher than the basic pitch S, the pitch changing means 25 determines the type of the pressed key (step C8), and the upper key is pressed. If so, the pitch of the note cell at position L is set one octave above the basic pitch S (step C15). When the pitch of the note cell at the position L is higher than the basic pitch S and the down key is pressed, the pitch changing means 25 changes the pitch of the note cell at the position L to the basic pitch S. (Step C13). For example, if the pitch of the note cell at position L is “#C” and the basic pitch S is “C”, the pitch of the note cell at position L is raised by half a tone to “C”.

  If the pitch changing means 25 determines in step C6 that the pitch of the note cell at position L is equal to the basic pitch S, the pitch changing means 25 determines the document of the pressed key (step C9), and the down key is pressed. If so, the pitch of the note cell at position L is lowered by a semitone (step C11). That is, in Table 2, the note name of the note cell at position L is changed to the left one in the group where the stem sound of the note cell at position L is the same. When the pitch of the note cell at the position L is equal to the basic pitch S and the up key is pressed, the pitch changing means 25 raises the pitch of the note cell at the position L by a semitone (step C12). ). That is, in Table 2, the note name of the note cell at position L is changed to the right one in the group where the stem sounds of the note cell at position L are the same.

  Returning to FIG. 7, the control unit 10 determines whether or not the note (101 to 107) or the rest key (100) is pressed (step B9). When a note or rest key is pressed, the control unit 10 inserts a note or rest corresponding to the pressed key at the current cursor position by the note / rest insertion means 23 (step B10). . Thereafter, the cursor position is advanced by one to the right. If the cursor position is not at the end, the “insert mode” is turned on (step B11), and the process returns to step B2.

  FIG. 9 shows the procedure of the note / rest insertion process. The note / rest insertion means 23 determines whether or not the pressed key is a rest key (step D1). The note / rest insertion means 23 inserts a rest at the current cursor position when the pressed key is a rest key (step D8). At this time, the note value of the rest is the same as that of the immediately preceding note or rest. When there is no note or rest immediately before, that is, when the cursor position is at the head, the note value of the rest is set as a quarter rest.

  When the note key is input, the note / rest insertion means 23 acquires the key at the current cursor position by the key acquisition means 22 (step D2). This process is the same as step C2 in FIG. The note / rest insertion means 23 determines whether or not a key is specified (step D3). If a key is not specified, the note that has been pressed within a range on the music for which no key is specified. Search for a stem corresponding to the key, that is, a note having the same stem as the stem of the note cell to be inserted. When there is a note having the same stem sound in a range where the key is not specified, the note / rest insertion means 23 specifies the nearest note before and after the insertion position among the notes having the same stem sound. . The note / rest insertion means 23 checks whether or not a change symbol (♭, ♭♭, #, ##) is attached to the specified note, and if it is attached, acquires the type (step). D4).

  The note / rest insertion means 23 determines the pitch name of the note cell to be inserted according to the presence / absence and type of the change symbol checked in step D4, and then determines the octave to determine the pitch. Determine (step D5). The note / rest insertion means 23 assigns the note name with the same change symbol as the change symbol checked in step D4 to the stem tone (Table 1) corresponding to the pressed key as the note name of the note cell. To do. The note / rest insertion means 23 is, for example, when the key 101 (“1”) corresponding to the stem sound “C” is input and “#C” is present in the immediate vicinity of the range where the key is not specified. In step D5, “#C” is determined as the note name to be inserted into the note cell.

In step D5, the note / rest insertion means 23 is set to the combination of the stem sound corresponding to the pressed key and the stem sound of the note of the note cell immediately before the note insertion position and the immediately preceding note cell. The octave of the note to be inserted is determined based on the octave. Table 5 below is used to determine the octave. In Table 5, “0”, “+”, and “−” represent operations for the octave. “0” indicates no octave change, that is, setting the same octave as the octave in the immediately preceding note cell. “+” Indicates that the next octave is set, and “−” indicates that the lower octave is set. The note / rest insertion means 23 uses the data shown in Table 5 and uses the same octave as the octave in the immediately preceding note cell by one by the combination of the stem sound of the immediately preceding note and the stem sound of the inserted note. Set octave or lower octave.

  If the note / rest insertion means 23 determines that a key is designated in step D3, it determines the pitch of the note cell to be inserted according to the key type (step D6). In step D6, the note / rest insertion means 23 first refers to Table 4 and obtains a set of basic pitches that can correspond to the key of the current cursor position. For example, if the key is in F major, “F, G, A, ♭ B, C, D, E” is acquired as a basic set. The note / rest insertion means 23 examines the note name of the element represented by [# | ♭] Y included in the acquired basic set, where Y is the stem sound corresponding to the pressed key, and uses the note name as the note name. And determined as the note name of the note to be inserted. For example, when the key 107 (“7”) corresponding to the stem sound “B” is pressed, “♭ B” is determined as the note name of the note cell. The octave determination is the same as the octave determination in step D5.

  The note / rest insertion means 23 inserts the note having the pitch determined in step D5 or D6 at the current cursor position (step D7). The note / rest insertion means 23 sets the same note value as the immediately preceding note or rest for the note value of the note. In the case of the beginning of the melody, it is a quarter note.

  In the present embodiment, the key designating unit 21 can set the key of the music to the first or middle note cell. Thereby, when a melody creator inputs a note, it can know that the part on the music in which the input note is located is in a tone, or that the key designation is released, Easy note input. In the present embodiment, when a key is specified at the note input position, the note / rest insertion means 23 uses the note name to which the presence / absence and type of the change symbol based on the key is applied as the first candidate. Insert into cell. Thereby, the trouble of inputting a change symbol can be saved.

In Patent Document 1, note input is performed without a change symbol by inputting a key to which a stem tone is assigned, and then the direction keys are operated to adjust the up / down of semitones. In Patent Document 1, if there is a key designation and a change symbol is attached to a specific note name in principle, it is necessary to repeat the specification of the stem sound and the input of the change symbol, and the input of the change symbol is complicated. In this embodiment, the melody creation device has key information of the melody as part of the data (Table 4). When inputting notes, only key input corresponding to stem sounds is performed using key information. Determine the note name to be taken in that key. By doing in this way, when inputting the melody with a key signature and a change symbol, the number of key inputs can be reduced compared to Patent Document 1. In addition, the melody creator can create a melody without being aware of the change symbols unique to the key.

  Further, in this embodiment, when there is no key designation at the note insertion position, the note / rest insertion means 23 includes a note insertion position and is in the same range before and after the range on the music that is not designated. Searches for notes with the same stem sound that is closest. The note / rest insertion means 23 checks whether or not a change symbol is attached to the searched note, and if so, checks the type. After that, the note / rest input means inserts, into the note cell, the first candidate with the same change symbol as the change symbol attached to the searched note. By doing so, it is possible to save the trouble of inputting the change symbol. This effect can be similarly obtained in a portable terminal device (melody creating device) that does not specify a key.

  In the present embodiment, the pitch changing means 25 raises and lowers semitones and inputs change symbols when the up and down keys 118 and 121 are pressed. Since the up / down keys 118 and 121 are assigned to the keys for inputting the change symbols, the melody creator can input the change symbols included in the melody sensuously. In this embodiment, the up and down keys 118 and 121 are used for raising and lowering the octave in addition to raising and lowering the semitone according to the relationship between the pitch of the note cell whose pitch is to be changed and the basic pitch. In this embodiment, by pressing the up / down keys 118, 121, the octave can be corrected up and down by one octave without changing the stem sound.

  In the present embodiment, the note / rest input means 23 has the same octave as the immediately preceding note, one octave lower than the immediately preceding note, according to the relationship between the immediately preceding note and the note to be inserted, when inputting the note. Or, an octave higher than the immediately preceding note is set. Generally, there is not much difference in pitch between two consecutive notes included in a melody. Using this property, the same octave as that of the immediately preceding note is set when the pitch difference is not more than a predetermined frequency, and if the pitch difference is not less than the predetermined frequency, the octave is raised or lowered. The predetermined pitch difference is, for example, 4 degrees. In this way, the melody creator can reduce the number of operations for changing the octave. Although the octave operation table (Table 5) is used above, the octave operation can also be determined from the pitch difference.

  As mentioned above, although this invention was demonstrated based on the suitable embodiment, the melody creation apparatus, method, program, and portable terminal device of this invention are not limited only to the said embodiment, The said embodiment A configuration in which various modifications and changes are made from the above configuration is also included in the scope of the present invention.
