Description

The present invention relates to electronic musical instruments, electronic equipment, and programs.

Rhythm, melody and harmony are said to be the three major elements of music. In modern music, the concept of chords has been proposed to represent harmony, and chords are represented by chord symbols. If you can play while looking at the score that describes the chord progression of the song (so-called chord notation), you will be close to stepping up from a beginner.

However, playing chords is quite difficult for beginners of guitar, for example. In other words, it takes a lot of practice to be able to unconsciously hold chords and change positions by looking at chord symbols. In addition, although there are individual differences, it takes a considerable amount of time in addition to patient practice to acquire playing techniques such as strokes and arpeggios. The situation is the same for players of keyboard instruments such as the piano, and learning chords is one of the reasons why beginners stumble. Many people have the impression that playing a musical instrument is difficult not only because of the improvement in playing technique, but also because learning chords is a burden.

Electronic musical instruments play a role in shortening the distance between users and music. For example, Patent Literature 1 discloses an electronic musical instrument in which root information, which serves as a reference for chord-composing tones, can be input using a joystick, and pitch information for chord-composing tones can be input using several buttons.

Japanese Patent Application Laid-Open No. 2005-284220

If the root and constituent notes of a chord are specified on an electronic musical instrument, it is possible to cause the sound source to produce chords. However, it is difficult to express various playing techniques. Electronic musical instruments are also known that allow chords to be easily specified by individually specifying the root of the chord symbol and the chord type, but it still requires practice to immediately specify the corresponding chord from the chord symbol. . Furthermore, if both hands are occupied just by specifying chords, it is far from expressing nuances by making full use of playing techniques.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an electronic musical instrument that allows users to easily enjoy playing chords.

To achieve the above object, an electronic musical instrument according to an embodiment of the present invention has a plurality of pitch name designation buttons each associated with a pitch name, and is formed in an annular shape rotatable around an axis. a dial section, a plurality of code type designation buttons each associated with a code type, and a processor. The processor comprises a constituent sound identifier and a phonetic message generator. The constituent note specifying unit specifies the constituent notes of the chord based on the note name specified by the note name specifying button and the chord type specified state by the chord type specifying button. The pronunciation message generation unit generates pronunciation message data including pronunciations of a plurality of sounds corresponding to the identified constituent sounds. A plurality of code type designation buttons are arranged in a circle inside the dial portion.

According to the present invention, it is possible to provide an electronic musical instrument with which chord performance can be easily enjoyed.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings.
<Configuration>
FIG. 1 is an external view showing an example of an electronic musical instrument 10 according to an embodiment. The electronic musical instrument 10 has a box-like housing, for example, and includes a dial section 11 , a plurality of chord type designation buttons 12 , a touch pad 13 , and an operation section 14 .

The dial section 11 has a ring shape and is mounted on one surface (operation panel) of the housing of the electronic musical instrument 10 so as to be rotatable in either the left or right direction or in both the left and right directions. A rotation mechanism (not shown) allows the dial section 11 to rotate around an axis perpendicular to the surface of the operation panel. Furthermore, the dial portion 11 can be rotated with a click feeling by a hooking mechanism (not shown) provided together with the rotating mechanism.

That is, when the dial portion 11 rotates from one rotational position (rotational angle) to another rotational position, when the boundary between the rotational positions passes through a specific position on the circumference, the hooking mechanism allows the operator to is formed to feel resistance (click feeling). Since rotation cannot be stopped at a position (boundary between rotational positions) where a click sensation occurs due to interference of the hooking mechanism, the operator can easily stop rotation at a specific rotational position (rotational position other than the boundary). . In this embodiment, 12 rotation positions are provided at which a click feeling is generated.

For example, the hook mechanism is provided with a projection made of an elastic member (e.g., leaf spring) at one arbitrary position (e.g., 12 o'clock position) on the outer periphery of the dial portion 11, and 12 positions on the rotational position boundary of the dial portion 11. It can be realized by providing another projection so as to interfere with the projection on the side. Of course, any other configuration may be used as long as a click feeling can be obtained.

Further, the dial section 11 is provided with 12 tone name designation buttons 15, and each tone name designation button 15 is written with a tone name of 12 tones of equal temperament. The pitch name designation buttons 15 are arranged so that their boundaries correspond to the 12 rotational positions where the above-described click feeling is generated. That is, when the operator rotates the dial portion 11, the boundary between the adjacent pitch name designation buttons 15 rotates (rolls) with a click feeling when passing a specific position on the circumference. Therefore, when the operator rotates the dial section 11, it becomes easier for the operator to grasp the boundaries of each of the pitch name designation buttons 15, and the position of the specific pitch name designation button 15 is fixed at the desired rotational position. becomes easier.

Any of the pitch name designation buttons 15 can be pressed with a finger. When the pressed finger is released, the pitch name designation button 15 returns to its original state. The button may be illuminated only while it is being pressed. Each note name designation button 15 may be individually color-coded.

The code type designation buttons 12 are arranged in a circle inside the dial section 11, for example. Each chord type specifying button 12 is associated with, for example, the seventh chord (7, 7th), minor chord (m), major seventh chord (M7), and the like. Incidentally, the state in which the chord type specifying button 12 is not pressed corresponds to a major triad chord. In the embodiment, 9 types of code types are assumed and 8 buttons are assumed, but the number is not limited to this.

The dial section 11 has a size that can be operated with one hand (for example, the left hand), and the chord type designation button 12 and the note name designation button 15 inside it can be pressed with one hand at the same time. The operation unit 14 is also used as a volume knob or the like for giving various settings to the device, selecting the tone color of the built-in tone generator, or controlling the output sound volume.

The touch pad 13 as a sound generation control unit is a sensor on a flat plate known as a pointing device of a notebook computer or the like, and is a human-machine interface that detects changes in capacitance, for example. In the embodiment, the touch pad 13 accepts a performance operation with one hand (for example, the right hand) of the user. For example, tapping with fingers, scratching, tracing, alternate tapping with two fingers, and the like are conceivable as performance operations.

The touch pad 13 sounds chords based on the combination of the note name designation button 15 and the chord type designation button 12 while the finger is in contact with the touch pad 13 . It is possible to control the pronunciation method by the way of touch. For example, the following five pronunciation patterns are conceivable, but are not limited to these.
(1) Tap with one finger (or simultaneously with multiple fingers). Pronounced while touching the touchpad.
(2) Ascending chords (arpeggios) are generated by successively tapping to the right without releasing the finger that first touches the touch pad 13 .
(3) A descending arpeggio is generated by tapping the finger to the left one after another without releasing the finger that first touched the touch pad 13 .
(4) When the touch pad 13 is tapped in a trilling manner, a sound is generated like a drum paradiddle playing style (playing style combining two-handed alternate playing and one-handed playing).
(5) When the touch pad 13 is scratched (scratched), sounds are produced separately like strumming of a guitar (strumming of a plurality of strings in a direction intersecting the strings from one to the other or vice versa). .

FIG. 2 is a top view of the electronic musical instrument 10 shown in FIG. The dial portion 11 can rotate clockwise, counterclockwise, or both, like the bezel of a wristwatch. A pointer mark 16 indicating the default position is drawn, for example, at the 12 o'clock position on the operation panel. By aligning the pitch name with the pointer mark 16, the rotational position of the dial section 11 is determined. FIG. 2 shows a state in which pitch name C is designated. This state designates the key of C major (C major) with C as the tonic. C major” etc.).

As shown in FIG. 2, the pitch name designation button 15 of the dial section 11 has 12 pitch names written one by one. When the [C] button is pressed without pressing the chord type specifying button 12 and the touch pad 13 is operated, a C major chord whose root is the C note sounds. Similarly, pressing only the [G♭/F#] button will sound G♭ major. That is, designation of the code type includes designation by not pressing the code type designation button 12 .

Furthermore, in the embodiment, the pitch name designation buttons 15 are arranged to form a so-called circle of fifths. That is, the pitch name designation buttons 15 are arranged in the dial section 11 such that the corresponding pitch names form a circle of fifths. As is well known, adjacent pitch names on the circle of fifths form the major triads of a diatonic chord.

Specifically, in the state of C major where the pitch name C in FIG. A G major chord in which a major 3rd (B or B) and a 5th (D or Re) are stacked on a G note is called a dominant chord in a C major song. The F on the left side of C is a 5th below C (4th above when counting upwards from C). An F major chord in which a major 3rd (A or La) and a 5th (C or C) are superimposed on an F note is called a subdominant chord in a C major song. A C major chord (CEG or Domiso), which is a similar superposition of notes on top of the C note, is called a tonic chord in C major songs. The chord relationships explained above also hold for all keys other than C major. In so-called popular music, there are a great many pieces of music composed only of three chords (tonic, dominant, and subdominant) of these three major chords. That is, in the majority of chord progressions, the note name designation buttons 15 to be pressed are gathered at close positions.

FIG. 3 is a diagram showing an example of the button group of the code type designation button 12. As shown in FIG. Each of the code type designation buttons 12 has a sector shape radially divided from the center (rotational axis) of the inner circle of the dial portion 11 . In FIG. 3, eight fan-shaped buttons are arranged. For each button, for example, clockwise from the 12 o'clock position, 3rd tone designation code, 4th tone designation system code, 5th tone designation system code, 6th tone designation total code, and 7th tone designation code are assigned. be done. Also, the chord types (m, dim, sus, ♭5, Aug, 6th, M7, 7th) with high frequency of use are indicated in this order. "m" (minor) designates the third above the root as a minor third (instead of a major third), so it is classified as a third designation code. "sus" is also described as sus4 (sus four or suspended force), and is classified as a fourth designation code because it adds a fourth instead of a third. Other chord types are classified in the same way, but only "dim" (diminished) is a special chord (a chord that stacks double notes on the root), and is placed next to "m" for convenience. .

All of the code type designation buttons 12 can be pressed with a finger, but cannot be rotated. When the pressed finger is released, the chord type designation button 12 returns to its original state. The button may be illuminated only while it is being pressed. Each code type designation button 12 may be individually colored.

A plurality of code type designation buttons 12 can be pressed at the same time. For example, in the 〇m7 chord, press [m] and [7], which are the same as the notation of the chord symbol, at the same time. In the 〇m7 (♭5) chord with the 5th lowered by a semitone, press [m], [7] and [♭5] at the same time.

FIG. 4 is a functional block diagram showing an example of the electronic musical instrument 10. As shown in FIG. The electronic musical instrument 10 includes a dial section 11, chord type designation buttons 12, a touch pad 13, an operation section 14, a processor 1, a ROM (Read Only Memory) 2, a RAM (Random Access Memory) 3, a sound source 4, a digital/ It has an analog (D/A) converter 5 , a speaker 6 , an interface section 7 and an internal bus 8 . Among them, the interface section 7 is connected to the dial section 11 , the code type designation button 12 , the touch pad 13 and the operation section 14 , converts the state of each section into digital data, and sends the digital data to the internal bus 8 .

The processor 1 is an arithmetic processing unit such as a CPU (Central Processing Unit) or an MPU (Micro Processing Unit), and implements various functions of the embodiment according to a program 2a stored in a ROM 2 . That is, the processor 1 reads the program 2a into the RAM 3 as a working memory and executes it.
The ROM 2 may store various setting data, tone color data, etc. in addition to the program 2a.

The tone generator 4 is, for example, a so-called GM tone generator conforming to the GM (General MIDI) standard. When the tone generator 4 receives pronunciation message data as MIDI (Musical Instrument Digital Interface) messages, for example, it reads waveform data corresponding to note numbers included in the pronunciation message data from, for example, a waveform memory (not shown). The read waveform data is converted into an analog waveform signal by the D/A converter 5 and output from the speaker 6 as a musical tone.

By the way, the processor 1 has a constituent sound identification unit 1a and a pronounced message generation unit 1b as functions related to the embodiment. The component sound identification unit 1a and the pronunciation message generation unit 1b are processing functions realized by arithmetic processing of the processor 1 based on the program 2a. That is, the program 2a includes an instruction for causing the processor 1 to execute the function of the component sound identifying section 1a and an instruction for executing the function of the pronunciation message generating section 1b.

The constituent note specifying unit 1a specifies the constituent notes of the chord of the chord type specified by the chord type specifying button 12, with the pitch name specified by the pitch name specifying button 15 as the root. For example, when [C] is pressed with the pitch name specifying button 15, the constituent note specifying unit 1a specifies C, E, and G, which are the constituent notes of the C major triad chord. Similarly, when [F] is pressed with the pitch name specifying button 15 and [m] and [7] are pressed with the chord type specifying button 12 at the same time, the component note specifying unit 1a selects the component note of the [Fm7] chord. Identify F, A♭, C, E♭.

The phonetic message generation unit 1b generates phonetic message data including a plurality of pitches corresponding to the constituent sounds specified by the component sound specifying unit 1a. That is, when [C] is pressed with the pitch name designation button 15 and the touch pad 13 is operated, the pronunciation message generator 1b generates note-on messages of note numbers corresponding to C, E, and G pitches. Generates MIDI messages such as (start sounding) and note-off messages (stop sounding). At that time, the pronunciation message generating section 1b generates a MIDI message for causing the tone generator 4 to generate sound in a manner corresponding to the performance operation given by operating the touch pad 13. FIG. The touch pad 13 may be provided with a pressure sensor or the like, and velocity information corresponding to the strength with which the touch pad 13 is tapped may be added to the note message, or a vibrato effect may be generated in accordance with the strength with which the touch pad is pressed. A control message or the like to be generated may be generated. This MIDI message is immediately input to the sound source 4 (FIG. 4) via the internal bus 8, and chord tones corresponding to the performance operation are output from the speaker 6. FIG.

The message generation unit 1b may arbitrarily determine the pitch octave for each of the component sounds specified by the component sound specification unit 1a, and generates messages corresponding to a plurality of pitches with the same pitch name but different octaves. You can For example, if C, E, and G are specified, not only the three tones C3, E3, and G3, but also the tones C2 one octave lower than C3 and C4 one octave higher may be added. You may also add notes several octaves above or below. It is also possible to arbitrarily decide which of the constituent sounds to be added with an octave difference. For example, if you want to get the same sound as a C major chord played on a guitar, you can play C3, E3, and G3 corresponding to the pitches of the 5th to 1st strings when you press the low chord C major on your guitar. , C4, and E4. The above settings can be set in the electronic musical instrument 1 via the operation section 14, for example.

Although the manner of sound produced by operating the touch pad 13 has been described above, the specific sound produced when a C major chord (C, E, G) is designated is as follows. Here, the pitch octave is just an example, and the method of pronunciation is not limited to this.
(1) Tap with one finger (or simultaneously with multiple fingers). Simultaneously pronounce C3, E3 and G3 while touching the touchpad.
(2) By sequentially tapping the finger to the right without releasing the finger that first touches the touch pad 13, the sounds of C3→E3→G3 are sequentially repeated (ascending arpeggio).
(3) By sequentially tapping the finger to the left without releasing the finger that first touched the touch pad 13, the sounds of C3→G2→E2 are sequentially repeated (descending arpeggio).
(4) When the touch pad 13 is tapped like a trill, sounds of C3C3, E3E3, and G3G3 are repeated (drum paradiddle playing style).
(5) When the touch pad 13 is scratched (scratched) in the right direction in FIG. 2, C3, E3, G3, C4, and E4 are scattered in order, and when scratched leftward, E4, C4, G3, and E3 are produced. , and C3 (guitar strum style).

<Action>
Next, the operation of the above configuration will be described.
FIG. 5 is a diagram for explaining an example of chord performance using the electronic musical instrument 10. As shown in FIG. When the user wants to play a tune in the key of C major, the user turns the dial section 11 to align [C] with the pointer mark 16 as shown in FIG. Then, the dial part 11 is fixed and stabilized with a "click" feeling.

If the chord progression of the music is as shown in FIG. 5(b), the user presses the note name designation button 15 and the chord type designation button 12 as the music progresses, as shown in FIG. 5(c). As indicated by hatching, CM7 has [C] sound and [M7] button, Dm7 has [D] sound, [m] button and [7] button, FM7 has [F] sound and [M7] button, In G7, the [G] sound and the [7] button are respectively pressed. At the same time, the user can enjoy the performance by operating the touch pad 13 to designate the sounding form such as strokes and arpeggios.

FIG. 6 is a diagram for explaining another example of chord performance using the electronic musical instrument 10. FIG. When playing a tune in the key of A major, the user turns the dial section 11 to align [A] with the pointer mark 16 as shown in FIG. 6A, and designates root=A. If the chord progression is IM7->IIm7->IVM7->V7 as in FIG. 5, the constituent sounds of each chord are naturally different. However, as shown in FIG. 6(c), the button to be pressed is exactly the same as in FIG. 5(c).

That is, by rotating the dial part 11 and aligning the pitch name designation button 15 corresponding to the tonic sound (root) of the key with the predetermined position (pointer mark 16), the pitch name can be specified regardless of the key of the music. The positional relationship between the button 15 and the code type designation button 12 is exactly the same. In other words, for the user, the way the buttons are pressed (chord form) remains constant even if the key changes. You will be able to play the songs of

By aligning the pitch name designation button corresponding to the tonic sound (tonic) of the key to the default position, the positional relationship between the pitch name designation button 15 and the chord type designation button 12 will be the same regardless of the key of the song. Although the effects described above can be obtained, it is of course possible to perform without such operations. For example, when playing a piece of music in which CM7 and C6 appear frequently, turn the dial unit 11 to move the C note button of the note name designation button 15 near the "M7" button and "6" button of the chord type designation button 12. This makes it easier to specify the code. Although it is not possible to obtain the effect of making the way of pressing the chord constant regardless of the key, the closer the positions of the note name designation button 15 and the chord type designation button 12 corresponding to the desired chord, the easier it is to press the button. The above effect of facilitating designation can be obtained. This effect is also obtained by the fact that the dial portion 11 can be rotated (rolled).

FIG. 7 is a flow chart showing an example of a processing procedure in the electronic musical instrument 10. As shown in FIG. First, the processor 1 of the electronic musical instrument 10 waits for designation of a root note by the pitch name designation button 15 (step S1). If the root note is designated (Yes), the processor 1 waits for a performance operation using the touch pad 13 (step S2). The presence or absence is determined (step S3).

If the code type has been designated (Yes), the processor 1 determines which code type designation button 12 has been pressed (step S4). If the chord type is not specified (No), processor 1 determines a default major triad chord (step S5).

Next, the processor 1 identifies constituent tones of the determined chord type based on the given root note (step S6), and generates a MIDI message including each note number of the identified constituent tones (step S7). . This MIDI message is given to the sound source 4, and a chord sound is output from the speaker 6 (step S8).

<effect>
As described above, in the embodiment, the operation surface of the electronic musical instrument is divided into 12 ring shapes having a certain width, and the dial portion 11 that can slide (rotate) left and right along the circumference is provided. The dial section 11 has pitch name designation buttons 15 for designating the respective pitch names, and each of the pitch name designation buttons 15 is labeled with roots of 12 scales. In addition, code type designation buttons 12 for designating code types are fixedly arranged inside the ring of the dial portion 11 .

By rotating the dial part 11 and stopping it at a predetermined position, the key of a piece of music is specified, and in the specified key, chords are specified by the note name specifying button 15 of the dial part 11 and the chord type specifying button 12 fixedly arranged. can be specified. As a result, chords that play the same role, such as tonic, dominant, and subdominant, in all keys have the same chord form. Therefore, once the chord form is memorized, it is possible to play music with the same chord form in all keys. In other words, just by memorizing the arrangement of the chord type designation buttons 12, the key can be easily transposed by rotating the dial section 11. - 特許庁Therefore, even a beginner can play chords with a minimum of practice and knowledge.

That is, according to the embodiment, the chord (chord) can be easily pronounced by visually pressing the chord symbol as it is, so there is no need to consciously memorize the chord constituent sounds.
Further, the pitch name designation buttons 15 are arranged so as to form a circle of fifths. The chord progression of many songs is theoretically easy to remember because the route is arranged according to the circle of fifths. Also, you can easily hold down the cord without having to spread your hand wide or twist your fingers forcibly.

Also, once the arrangement of the chord types is memorized, the time spent on improving the playing technique of the musical instrument can be shortened.
Furthermore, the method of tapping the touch pad 13 and the pronunciation are sensuously directly connected and easy to understand, and no special playing technique is required. From these things, it is possible to easily perform singing with a musical instrument, which was difficult because of the difficulty in learning musical instrument playing techniques, without spending time learning playing techniques.
Further, according to the embodiment, in a nursery school, a kindergarten, an elementary school, or the like, it is possible to easily play accompaniment to a chorus with children without relying on piano performance techniques.
In addition, you can easily play chords at various events. As described above, according to the electronic musical instrument 10 of the embodiment, it is possible to provide the joy of enjoying music in a familiar and easy manner.

As described above, according to the embodiment, by pressing the elements of the written chord symbols as they are seen, the constituent sounds of the chord can be formed and pronounced. This eliminates the need for time to understand and memorize the constituent sounds indicated by the chord symbols, nor the skill required to pronounce the sounds peculiar to the instrument, and minimizes the time for practice, allowing the user to concentrate on enjoying the music. That is, it is possible to provide an electronic musical instrument capable of playing chords corresponding to all keys with minimal practice and knowledge.

For these reasons, according to the embodiment, it is possible to provide an electronic musical instrument that allows users to easily enjoy playing chords. As a result, electronic musical instruments can make playing music even more enjoyable.

It should be noted that the present invention is not limited to specific embodiments. For example, the number of chord type specifying buttons 12 is not limited to eight, and the number may be increased so that various chords including tension chords can be specified. Reducing the number makes the device even more friendly to beginners. Depending on the user's age and skill, the number of buttons may be determined in several ranks.

In the present embodiment, both the note name designation button 15 and the chord type designation button 12 are described as being ON only while they are pressed. may be maintained. In that case, if the same button is pressed again, the ON state should be released and the state should be shifted to the OFF state. When the note name designation button 15 and the chord type designation button 12 are made to illuminate, the player can be notified that the button is on by illuminating the button while it is in the on state. The designated code type can be determined by visually checking whether is lit. In this way, after specifying a chord once, the player can remove his/her fingers from the buttons as long as the same chord continues, so that the touch pad 13 and the operating section 14 can be operated with both hands. can. Also, after specifying the root of the chord with the pitch name specifying button 15, when the chord type changes in the same route like C→C7, the chord type specifying button 12 can be operated only.

In this embodiment, chords are specified by the pitch name specifying button 15 and the chord type specifying button 12, and the performance mode is operated by the touch pad 13, but other configurations may be adopted. For example, the electronic musical instrument 10 may be provided with an automatic accompaniment function, and based on chords specified by the note name specifying button 15 and chord type specifying button 12, the automatic accompaniment pattern stored in the ROM 2, for example, may be produced. Furthermore, the touch pad 13 may be replaced with a keyboard operator. In this case, it is possible to play the automatic accompaniment by specifying chords by operating the note name specifying button 15 and the chord type specifying button 12 with the left hand, and play the melody by operating the keyboard operator with the right hand.

Also, the arrangement of the pitch name designation buttons 15 is not limited to that shown in FIG. The pitch name designation buttons 15 may be arranged in a circle of fifths clockwise from the root as shown in FIG. 8(a), or fifths counterclockwise from the root as shown in FIG. A circle arrangement may also be used. In addition, although a form in which a click feeling is generated when the dial portion 11 is rotated has been shown, in short, it is sufficient to be able to position the dial portion 11 at a specific rotational position, so it may be configured to rotate smoothly without a click feeling. .

Further, in the embodiment, the sound source 4 is mounted on the electronic musical instrument 10 so that it is completed in one housing. Alternatively, the sound source 4 may be separate and connected with a MIDI cable. Alternatively, while the tone generator 4 is built in, only the MIDI message may be taken out from the MIDI THRU terminal.
Alternatively, the functions of the electronic musical instrument 10 may be implemented as a program, distributed in the form of an application to electronic devices such as smartphones and tablets, and installed. In this case, the electronic device includes a touch panel and a display control section. The display control section displays the dial section and a plurality of code type designation buttons on the touch panel.

In addition, the technical scope of the present invention includes various modifications and improvements within the range in which the object of the present invention is achieved, which will be apparent to those skilled in the art from the description of the scope of claims. be.
