CONSTITUTION:The scale data is comprised of a part representing the principal tone(do, re, mi, fa, so, la, and si) and a part representing the derivative tone(do#, re#, mi#,...). Each scale data is inputted to a scale name discrimination part 106 and a tone height discrimination part 107 after being outputted from a scale register 104, and the data is inputted to a sound generating part 108. Also, tone height designation data is generated at the tone height discrimination part 107 similarly, and it is inputted to the sound generating part 108 and a musical instrument tone generating part 112. After that, an audio signal provided with tone height in accordance with the tone height designation data and representing the scale name in accordance with the scale designation data is outputted from the sound generating part 108, and the scale is vocalized from a speaker 114 via a sound system 113.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is capable of changing scale names of musical tones such as "do", "shi", "mi", and "fa" according to the player's performance operation or automatic performance.
Concerning an electronic musical instrument that vocalizes "so", "u", and "shi".

[Conventional technology]

When practicing playing a musical instrument or singing, it is common to sing melodies using scale names.

Normally, when a beginner learns to play the piano, etc., the teacher often sings the melody part using scale names, and the trainee practices along with it. In addition, in order to learn to sing, it is important to acquire the ability to read and sing music scores, that is, to acquire music reading ability, but in order to do this, it is necessary to repeatedly practice singing the notes of the melody using the scale names using the "1st scale name singing method". be.

For this reason, electronic musical instruments have been proposed that can vocalize melodies and other music using scale names (Japanese Patent Laid-Open No. 58-11986,
and Utility Model Publication No. 6O-70892).

In the former conventional example (Japanese Unexamined Patent Publication No. 58-11986), consonant audio data and vowel audio data for vocalizing scale names of musical tones are stored in a ROM.

Furthermore, musical tone data consisting of pitch data and note length data is stored in advance in a separate ROM. During practice, for example, when pitch data indicating the scale name "G" is read out, the consonant sound data "S" and the vowel sound data "0" corresponding to "G" are read out from the ROM. , “
The pitch is based on the pitch data of "G" and informs the scale name "
``Sooo...'' is uttered. Practitioners perform along with this.

Next, in the latter conventional example (Sho 6O-70892), the key of the song is specified in advance, and based on the pitch of the pressed key, the scale name of the pressed key in that key is voiced. is uttered. At that time, when a key corresponding to a note that is not included in the scale of the specified key is pressed, for example, for a note with an accidental, the sound ``han-on j'' is uttered.

For example, the C# and Dl> notes in C major are "Do Han On".
Or it is uttered as ``shi-han-on''.

[Problem to be solved by the invention]

However, in the case of the former conventional example, if a piece of music has accidentals (#, G, and natural symbols) and the pitch is about a semitone below the scale note of the specified key, how do you change the sound that informs you of the scale name? The technology for how to do this has not been disclosed.

Regarding the latter, each of the sounds [do, shi, mi, fa...] can be uttered in one syllable, and it harmonizes well with the rhythm of the song, but when it comes to the sounds ``do, shi, mi, fa...'', it harmonizes well with the rhythm of the song, but When such sounds are mixed, the problem is that not only will the scale names not be in harmony with the rhythm of the musical tones, but if the music has a fast tempo, the voices will be spoken too quickly, making it difficult to hear the scale names. have.

An object of the present invention is to make it possible to pronounce scale names that are in good harmony with the rhythm of a musical piece and are easy to hear even when the pitch of a musical tone is changed by a semitone using an accidental or the like.

[Means for Solving the Problems] The present invention first includes scale data generation means for generating scale data. This means includes 17 types of scale names for the 12 notes in the l octave (including scale names with the same pitch but different names, such as C# and b), and This is a means for generating scale data consisting of seven types of ``scale names to be uttered'' such as , mi, ... , shi, J, and pitch information for each of 12 semitones. More specifically, the scale data generation means includes, for example, a music data storage means such as a ROM that stores a plurality of scale data representing a music piece in pairs with each timing data that controls the readout timing of each of the scale data; The apparatus is configured to include a scale data reading means for sequentially reading each scale data from the data storage means at a timing based on the timing data while reading each timing data stored in pairs with each scale data. Alternatively, the music data storage means described above may be configured with a RAM, and may further include a writing means for writing each musical scale data and each timing data corresponding thereto into the music data storage means. The above-mentioned scale data includes, for example, a code indicating a condition for specifying the stem tone corresponding to the scale data as is, a code indicating a condition for raising the pitch by a semitone with respect to the stem tone, or a code indicating a condition for raising the pitch by a semitone. It can be expressed in either of the following ways.

Next, it has a floor name designation data generation means as described below. That is, when the scale data generation means generates scale data of a stem note, the means generates scale name designation data that specifies the scale name of the stem note based on the chord indicated by the scale data, for example.

On the other hand, when scale data for a derivative sound derived from a main note is generated, the scale name of the main note that is a semitone higher than the derived note, or the Generate scale name designation data that designates one of the scale names of the lower pitched main tone. That is, for example, when the scale data generation means generates scale data of the main note C, the means generates scale name designation data that specifies the scale name "C" of the main note. On the other hand, when the scale data of the derivative sound C# sound (=Db) derived from the main sound is generated, the scale name of the main sound that is a semitone higher than the derived sound is "shi" according to the preset conditions. Alternatively, scale name designation data is generated that designates either the scale name "C" for the main note C, which is a semitone lower.

Furthermore, it has a pitch designation data generation means for generating pitch designation data corresponding to the main note or derivative note indicated by the scale data generated by the scale data generation means. The means includes a scale data ordering means, for example, a ROM in which scale data is stored in advance.
This is a means for extracting the pitch information of the main tone or derived tone from the source, and generating pitch specification data based on it.

The instrument also includes a voice generating means for uttering the scale name corresponding to the scale name designation data generated by the scale name designation data generating means at a pitch corresponding to the pitch designation data generated by the pitch designation data generating means. The means includes, for example, a sound source means for generating a sound source signal of a pitch corresponding to the pitch designation data generated by the pitch designation means, and receives the sound source signal from the sound source means,
It can be configured to include voice synthesis filter means for synthesizing an audio signal representing the scale name corresponding to the scale name designation data generated by the scale name designation data generation means. The voice synthesis filter means is a means for synthesizing voice by controlling a sound source using, for example, white noise corresponding to unvoiced sounds and a triangular wave (or impulse wave) corresponding to voiced sounds, and filter coefficients of a digital filter. Alternatively, the sound generation means includes a waveform storage means for storing sound waveform data representing the scale name of the main tone, and a scale name corresponding to the scale name designation data generated by the scale name designation data generation means from the waveform storage means. It can be configured to include waveform reading means for reading out the represented audio waveform data at a speed corresponding to the pitch corresponding to the pitch specification data generated by the pitch specification data generation means. Here, the above-mentioned waveform storage means stores, for example, consonant audio waveform data representing the scale name of each stem tone and vowel audio waveform data representing the scale name of each stem sound, and the above-mentioned waveform reading means stores , after reading the audio waveform data representing the consonants of the scale name corresponding to the scale name designation data generated by the scale name designation data generating means, the means repeatedly reads the audio waveform data representing the vowels of the scale name.

As an aspect other than the present invention described above, the present invention can also be configured as follows.

That is, first, there is a condition setting means for setting a condition as to whether each derived note is derived from a main note that is a semitone higher than the derived note or is derived from a stem note that is a semitone lower than the derived note. The means determines whether each derived tone, for example, C# (=Db), is derived from a stem tone that is a semitone higher than the derived tone, or is derived from a stem tone that is a semitone lower than the derived tone. This is a means for setting these conditions in advance.

Next, if the input performance information is performance information that instructs the pronunciation of a stem note, scale name specification data that specifies the scale name of the stem note is generated, and performance information that instructs the pronunciation of derived notes is generated. In certain cases, according to the conditions set by the condition setting means,
It has a scale name designation data generation means for generating scale name designation data that designates either a scale name of a main note that is a semitone higher than the derived note, or a scale name of a main note that is a semitone lower than the derived note.

Then, a pitch specification data generation means similar to that described above,
and has voice production means.

[For production]

Based on the scale data generated by the scale data generation means, the scale name specification data generation means generates scale name specification data representing the scale names of the main tone and derived notes of each musical note, and based on this data, the voice generation A voice representing the corresponding floor name is uttered by the means. In this case, the speech is produced by a speech synthesis filter means or by using a waveform readout type vocalization means having a waveform storage means in which waveforms of consonants and vowels are stored in advance.

In particular, in the present invention, the sounds representing the floor names include "do", "shi",
For derived sounds that are uttered in only 7 types: ``mi'', ..., and ``j'', and the pitch changes by a semitone by adding an accidental to the main tone, only the pitch changes by a semitone. , the voice itself is uttered in one syllable using the scale name of the original key tone.For this reason, the scale name is easy to hear even in fast-tempo songs.

In addition, since it is possible to set in advance whether the stem tone corresponding to the derived note is a stem tone higher or lower by a semitone than the derived note, it can be set in advance as data or by a condition setting means. It is possible to pronounce the correct scale name according to the following.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

In this example, the scale name of each musical tone of a song is uttered in a voice with the same pitch as the musical tone, based on automatic performance data pre-stored in the sequencer or performance data obtained from a manually played instrument. be done. For derived tones whose pitch is changed by a semitone by adding an accidental to the stem tone, only the pitch changes by a semitone, and the sound itself is uttered using the scale name of the original stem tone. Further, in this embodiment, the scale name of each musical tone is represented by the scale name of C major key. In other words, an example is shown in which the scale name is determined by the pitch of a musical tone.

FIG. 1 is an overall configuration diagram of an embodiment of the present invention.

In the figure, the song ROMI O1 includes note length data for each musical tone and scale data as shown in FIG. 2 for vocalizing the scale name of each musical tone, as song data for automatic performance (sequencer). , are written for each specified song.

When the performer specifies a song using the song specifying section 103, the address of the song ROM 101 corresponding to the specified song is specified by the address specifying section 102. As a result, the scale data for each tone read from the music ROM10I is written into the scale register 104, and the note length data read out in the same manner is output to the note length control section 105.

The note length control section 105 sends an ON signal and an OFF signal to the voice generation section 108 and the musical instrument sound generation section 1 according to each note length data.
12, and the next musical tone continues to be music R.
Addressing part 1 as read from OMl0I
02 are sequentially controlled.

The above-mentioned scale data includes parts representing the main tones (C, C, M, F, G, U, C) and derived tones (C #, C, B), as described later.
, shi #, mid, ...). After each scale data is output from the scale register 104, it is input to a scale name discriminator 106 and a pitch discriminator 107. Thereafter, scale name designation data is created by scale name discrimination section 106, and the same data is input to voice generation section 108. Similarly, the pitch determining section 107 creates pitch specifying data and inputs it to the voice generating section 108 and the musical instrument sound generating section 112.

Thereafter, the sound generator 10 outputs an audio signal having a pitch corresponding to the pitch designation data and representing a scale name corresponding to the scale name designation data, and the scale name is output from the speaker 114 via the sand system 113. uttered. Furthermore, musical tone signals having a pitch corresponding to the pitch designation data are outputted from the musical instrument sound generating section 112, and are produced from the speaker 114 via the sand system 113.

The above-mentioned time when the scale name is uttered and the time when the musical tone is sounded are determined by the ON signal and O output from the note length control unit 105 according to each note length data of the designated song in the song ROMI Ol.
Controlled by FF signal.

The above is a case of automatic performance (sequencer), but in the case of manual performance, the performer sets how the above-mentioned derived sound will be uttered in the condition setting section 109, and then presses the keyboard 111. When operated, scale name/pitch determination section 110 inputs scale name designation data and pitch designation data corresponding to the pressed key to sound generation section 108, and outputs a corresponding sound signal. Further, pitch designation data corresponding to the pressed key is input to the musical instrument sound generating section 112, and a corresponding musical tone signal is output.

These audio signals and musical tone signals are transmitted to the sound system 1
The sound is generated from the speaker 114 via the sequencer 13 in the same manner as in the case of the sequencer described above.

In this case, an audio signal and a musical tone signal representing the scale name corresponding to the pressed key are output from the scale name/pitch determination unit 110 to the sound generation unit 108 and the instrument sound generation unit 112 in accordance with the key depression and key release. It is controlled by the output ON signal and OFF signal.

Next, the operation of this embodiment will be explained separately for automatic performance using a sequencer and manual performance.

First, in the case of automatic performance by a sequencer, the scale names of musical tones are uttered based on scale data as shown in FIG. All scale names of one octa's worth of main notes and derivative notes, including scale names with the same pitch but different names, such as "C#" and "Shishi," are 5-bit 2. It is expressed in decimal numbers.

Of these 5 bits of data, the upper 2 bits are the main tone (0
0), a derived note with # (01), or a derived note with G (10), and the lower 3 bits are the scale name of the main note C (001), Shiku010, Mi (011)
, Fa (100), So (101) U (110), Shi (
111).

Regarding this scale data, for example, C # (01001)
and Leto (10010), when the pitch is the same but the scale name is different, the scale data is different.

In order to vocalize the scale name based on this scale data, the scale name determination unit 106 creates scale name designation data as shown in FIG. 2 based on the scale data output from the scale register 104. be done. For example, the scale name data C (00001) and C # (01001) both have C as their main note, so even if their pitches are different, they are treated as the same scale name specification data (001), and the scale name is pronounced as ``Do J''.

On the other hand, in order to determine the pitch from the scale data shown in FIG. 2 etc., pitch specification data as shown in FIG. 107.

Here, even if the same scale name is designated by the scale name designation data, the pitch may be different, as in the case of C and C# in the scale data in the above example, for example.

In this case, different pitch designation data corresponding to different scale data are generated by the pitch discrimination section 107 and provided to the sound generation section 108. As a result, an audio signal representing the same scale name corresponding to the scale name designation data is generated with a different pitch corresponding to the pitch designation data. That is, in this embodiment, a certain stem tone and a derivative tone derived from the stem tone, such as C and C# in the scale data of the above example,
The scale name will be the same (in the above example, "C"), but the pitch of the voice representing that scale name will be the same as the pitch corresponding to the original scale name (in the above example, C and C#). be done.

This way of expressing scale names is exactly the same as the method of singing scale names in vocal music based on the ``fixed C'', and it harmonizes well with the rhythm and accent of the melody.

The above explanation is for a case where the sequencer automatically vocalizes scale names of songs such as melodies stored in the music ROM 104, and the learner learns singing and playing musical instruments while listening to the voices.

Next, the operation of this embodiment during manual performance will be explained using a keyboard instrument as an example.

In the case of manual performance, it is first necessary to decide on the scale name of each musical note of the piece of music to be played, especially the scale name to be used for the derived notes such as #yashi added to the main tone. For example, when a black key corresponding to C# (=Db) is pressed, the scale name of that note is determined in advance as either "C#" or "Shib" (.

Therefore, the performer uses the input section 302 of the condition specifying section 301 (see FIG. 3) in the condition setting section 109 (FIG. 1) to preset the scale of each note within one octave as shown in the same figure. Set conditions for how names are represented. For example, if the music to be played is in E major as shown in the display section 303 of the same figure, G is added to the G, C, and M sounds, so the input section 30
In step 2, settings are made using ``u'', ``shi'', ``mi'', and ``p'', and by this operation, each of the flags RARE, SIb, and MIDO in the flag register 303 is set to 1.

After the conditions of scale names for representing derived notes are set in this way, a performance operation is performed, and the key code corresponding to the pressed key is input to the scale name/pitch determination section 110.

Then, scale name designation data and pitch designation data similar to those for the sequencer are created from this key code, and are input to the voice generation section 108 and the musical instrument sound generation section 112, respectively.

For example, if the black key between “u” and “shi” is pressed under the above-mentioned condition setting in the condition specifying unit 301, based on the settings of the flag register 303 in the condition specifying unit 301, In the scale name/pitch determination unit 110, 110 is the scale name designation data, and 1001 is the pitch designation data (
(see Figure 2) is created.

As a result, the sound generation unit 108 produces a sound representing the scale name at a pitch corresponding to the pitch designation data. Further, the musical instrument sound generating section 112 generates a musical tone signal having a pitch corresponding to the pitch designation data.

Note that the start/stop of voice production or musical tone production is controlled by ON and OFF signals output from the scale name/pitch determination unit 110 in response to key depression and key release.

The subsequent operation is similar to that of the sequencer described above.

Next, a specific example of the configuration of the sound generation section 108 that generates sound will be explained using FIGS. 4 and 5.

FIG. 4 is a block diagram of the first embodiment of the sound generation section 108.

In the figure, a child sound waveform and a following vowel sound waveform are synthesized in a digital filter part 404 using white noise and a triangular wave (or impulse wave) generated by a sound source signal generation part 403.

Now, when humans utter a voice, they change their vocal tract according to the voice. In the same way, the digital The filter characteristics of the filter section 404 are changed in accordance with the scale name.

In the first embodiment of the sound generation section 108 described above, first, the sound source signal generation section 403 first generates white noise in accordance with the ON signal and the unvoiced sound instruction signal output from the control section 401, and then the white noise is generated. , a triangular wave (or impulse wave) is generated according to the inputted voiced sound instruction signal. Here, the white noise is used as an input waveform for generating a consonant waveform, which is an unvoiced sound, in the digital filter section 404, and is generated based on, for example, random numbers. In addition, triangular waves (or impulse waves) are used to generate vowel waveforms, which are voiced sounds, and their repetition frequency is
A pitch designation signal generated based on pitch designation data input to the control unit 401 is set to be equal to the fundamental frequency of the voice representing the scale name.

In this way, the white noise and then the triangular wave (or impulse wave) are sequentially input to the digital filter section 404, where a child sound waveform and a vowel sound waveform corresponding to the scale name are sequentially generated.

This digital filter 404 is, for example, LPClPAR
It is a speech synthesis filter such as COR, LSP, or cepstrum, and its filter coefficients are changed according to the consonants and vowels of the speech representing the scale name.

For example, when uttering the scale name "So (So) J", the control unit 401 selects a filter coefficient corresponding to the consonant "s" and a filter coefficient corresponding to the vowel "o" from the filter coefficient ROM 402 according to the scale name specification data. As a result, the filter characteristics of the digital filter section 404 are changed in accordance with the temporal waveform change from consonant to vowel.

In this way, the digital filter section 404 outputs audio waveform data representing scale names of "do, shi, mi, . . . , shi" at pitches corresponding to the pitch designation data.

Next, FIG. 5 shows the configuration of a second embodiment of the sound generating section 1o8 shown in FIG. 1.

First, an overview of the operation of the second embodiment will be explained.

In the figure, the human voice sound waveform data memory section 5°8 stores the consonant and vowel sound waves representing each scale name of "do, shi, mi, fa...shi" as shown in FIG. The shape is rising (
Consonant) waveform “d” and sustained (vowel) waveform “o” (0)
It is divided into and stored. For example, when scale name designation data that specifies the scale name "do (do) )" waveform area is repeatedly (looped) read out for a predetermined period of time. The pitch of the voice in this case is determined by specifying the address sidewalk width when reading the voice waveform data stored in the human voice waveform data memory unit 508 using the pitch specification data output from the control unit 501. controlled.

First, the floor name designation data is sent to the control unit 50 along with the ON signal.
1 to the rising waveform start address generating section 502, a start address for reading out the rising (consonant) waveform corresponding to the scale name designation data from the human voice waveform data memory section 508 is generated. Thereby, the address signal generating section 503 sequentially outputs the addresses where the rising (consonant) waveform data are stored to the human voice waveform data memory section 508, and reading of the waveform data from the memory is started. At this time, since the pitch designation data has been input to the address signal generation section 503,
An address signal is generated with a sidewalk width corresponding to the pitch.

Thereafter, when the rising waveform end address detection section 506 detects the end address of the rising (consonant) waveform output from the address signal generation section 503, the end address detection signal is sent to the continuous waveform start address via the OR gate 505. The signal is input to the generation unit 504.

As a result, from the same address ordering unit 504, the control unit 50
A start address i for reading out a continuous waveform, which is a vowel waveform corresponding to the scale name designation data input from 1, from the human voice waveform data memory unit 508 is generated. Thereby, the address signal ordering unit 503 sequentially outputs the addresses where continuous waveform (son waveform) data are stored in the human voice waveform data memory unit 508, and the waveform data is read from the memory. At this time, since the pitch designation data has been input to the address signal generation section 503, an address signal is generated with a sidewalk width corresponding to the pitch.

After that, continuous waveform end address detection section 507 → OR gate 505 → continuous waveform start address generation section 504 →
A loop process is performed in a signal flow from the address signal generation unit 503 to the continuous waveform end address detection unit 507, and reading of the continuous waveform (vowel waveform) is continued.

Then, when the OFF signal is input to the continuous waveform start address generation section 504, the above loop processing is stopped.

As described above, while the ON signal continues, among the audio waveform data representing the scale name, the rising (consonant) waveform data shown in FIG. 6 is repeated once, followed by the continuous (vowel) waveform data, The human voice sound waveform data is read out from the memory section 508.

Thereafter, the same audio waveform data is combined with the envelope signal output from the envelope signal generator 509 and the multiplier 510.
The result is an audio signal with an envelope suitable for uttering the scale names of "do, shi, mi, fa...shi".

Note that PCM, DPCM, AD
A method such as PCM can be applied.

Next, an embodiment will be described in which the user can set automatic performance data on the sequencer. FIG. 7 is an explanatory diagram of the embodiment.

In the embodiment of FIG. 1 described above, the music ROM 101
In the case of Fig. 7, data regarding scale names and note lengths of specific songs were written in advance at the factory.
A music RAM 707 is provided in place of 10I, and the user can store data regarding scale names and note lengths of any music one note at a time in the music RAM 707. Such an input form is generally called step input. The scale register 104, tone length control section 105, and the subsequent configurations are the same as in the case of FIG. Below is the song RA
The configuration of the part for writing automatic performance data into M707 will be mainly explained.

Now, in FIG. 7, the scale name data input section 701 is connected to the condition specifying section 301 (third
It is almost the same as the input section 302 of the 8-octave range (see figure), but is configured so that scale name data can be input over an 8-octave range. For example, the note name AO (27.5Hz) is the lowest note, and the pitch range is 0ctl, 0c for each octave.
t2. ...If 0ct8 is set, for example, if the 04th note of a C major song is input step-by-step, the 04th note of a C major song is within the range of Oct4 and its scale name is G, so rOct4j and "S" are input. Also, if the song is in A minor, the G4 note will have an accidental #, so
"S" and "#" are input.

The note length data input section 702 is for inputting note lengths including rests in steps, and depending on the music, whole notes, half notes, . . . , 32nd notes as shown in the figure are input. Triplets, dots, and quarter rests are entered.

Then, by pressing the increment switch 705 and the write switch 704 for each data step input, data regarding scale names and note lengths are sequentially written into the music RAM 707 via the write control section 703. Note that the address of the music RAM 707 at this time is specified by the address specifying section 706.

The data written to the music RAM 707 described above is simultaneously displayed in the form of a musical score on the music display section 709 by the display driving section 708, so that the data to be written can be confirmed.

The above is the operation when inputting scale name data and note length data into the music RAM 707 by step input. Based on this input data, the scale name is uttered aloud as follows.

First, when a song is specified by the song designation section 710 (corresponding to 103 in FIG. (corresponding to 102).

As a result, the scale data and note length data are stored in the song RAM 7.
It is read from 07.

After this, the tone length control section 710, address specification section 706,
The operation of the scale register 711 is the same as that of the sequencer described above (FIG. 1), so a description thereof will be omitted. However, unlike the case of FIG. 2, the musical scale data and the pitch designation data based thereon can be designated for more than one octave.

As explained above, by automatic performance or manual performance, the scale name of each musical note in a specified song (in automatic performance) or any song (in manual performance) is changed to a voice with the same pitch as that musical note. uttered. In this case, the scale name of the derived note is represented by the same scale name as the main note according to the preset conditions.

In each of the embodiments described so far, scale names for musical tones to be played are independent of the key of the piece. Although the scale name is expressed in the C major key, the present invention is not limited to this, and the scale name can also be expressed in the following way.In other words, the tonic (first note) of the major key being played is "Do" in floor name
, minor key, the method is to use the tonic as the scale name ``UJ'' (called the moving ``C'' singing method). In the case of automatic performance (sequencer), create the scale data and scale name specification data shown in Figure 1 according to this method, and in the case of manual performance, use a key specification device, etc., to create the music to be played. It is also possible to input key data specifying the key in advance.

Further, in the embodiment shown in FIG. 1, the scale data is specified for one octave only, and the pitch specification data is also specified for only one octave, but this is not limited to this, and multiple octaves may be specified. Of course, it is also possible to configure it in this way. However, since the scale name uttered from the sound generation unit 108 (FIG. 1) is uttered at the pitch specified by the pitch specification data, it may be limited to pitches that can actually be uttered by humans. desirable. In this case, the pitch of the musical instrument sound produced by the musical instrument sound generating section 112 may be specified within a wide range.

〔Effect of the invention〕

According to the present invention, sounds representing floor names include "do", "shi",
For derived sounds that are uttered in only 7 types: "mi", ... "shi", and the pitch changes by a semitone by adding an accidental to the main sound, only the pitch changes by a semitone, The voice itself is uttered in one syllable using the scale name of the original stem tone. This makes it easy to hear the scale names even in fast-paced songs. That is, the sounds representing the scale names uttered according to the present invention harmonize well with the rhythm and accent of the melody, and the scale names are easy to hear, which is highly effective for music learning.

In addition, whether the stem tone corresponding to the derived note is a stem tone that is a semitone higher or a semitone lower than the derived note is determined in advance as data (in the case of automatic performance) or by condition setting means (in the case of manual performance). case), so you can set
