The chord designation button group 3 consists of a plurality of chord designation buttons 3A to 3I, which are arranged side by side on the neck portion 24. As shown in FIG. The plurality of chord designation buttons 3A to 3I are formed, for example, in a rectangular shape and are arranged in a two-dimensional array or a staggered array. In this embodiment, nine chord designation buttons 3A to 3I are arranged in a two-dimensional array of three vertical rows and three horizontal rows.

A chord is assigned to each of the chord designation buttons 3A to 3I. Specifically, a first root note and a first chord type forming each chord are assigned to the plurality of chord designation buttons 3A to 3I, respectively. The assignment state of the chords assigned to the plurality of chord designation buttons 3A to 3I is not fixed, but can be changed according to a plurality of changing methods (details will be described later).

Here, a "chord" is a combination of at least three or more constituent tones having different pitches based on the root note, which is the lowest note of the chord. Each chord is specified based on a "root note" and a "chord type" indicating characteristics of other constituent notes (third note, fifth note, seventh note, tension, etc.) other than the root note. Indicated by name. The "chord name" is represented by capital letters (A to G) for the "root note" and by alphanumeric characters and Greek letters placed to the right of the capital letters (A to G) for the "chord type". be.

A "root" is written by adding "♭" or "#" to uppercase letters of the alphabet (A to G). "Chord types" (names in parentheses) are, for example, "m" (minor), "m7" (minor seventh), "aug" (augment), "7" (seventh), "M7" ( major seventh), "6" (six), "9" (ninth), "O" (diminished), "7sus4" (seventh sus-four), and "Φ" (half-diminished). Note that "O" is a shorthand notation for "dim7" and "Φ" is a shorthand notation for "m7 ^♭5 ". Also, when the "chord type" is "M" (major), the notation of "M" is omitted.

Chords include major chords I, IV, and V, and minor chords II, III, VI, and VII, and the number of basic root notes is limited to seven. Furthermore, for example, in triads in the natural major scale, the basic chord types are major triads (major) when root notes are I, IV, and V, and major chords when root notes are II, III, and VI. , a minor triad, and if the root note is VII, a diminished triad.

Therefore, in the present embodiment, the first root note and the first chord type that make up each chord are narrowed down to the basic root note and chord type as described above, and arranged regularly. Chord designation buttons 3A to 3F and 3H are indicated by code names "C", "Dm", "Em", "F", "G", "Am" and "Bm" as initial allocation states. seven chords are assigned to each. Also, as a chord having a higher frequency of use than other chords, one chord designating button 3G is assigned a chord with a chord name "B ^♭ " as an initial assignment state. In this embodiment, it is assumed that no chord is assigned to one chord designation button 3I, but any chord may be assigned to the chord designation button 3I.

A plurality of change methods for changing the assignment of chords to the plurality of chord designation buttons 3A to 3I are assigned to the plurality of chord change buttons 4A to 4K, respectively.

Here, the "change method" is a method of changing at least one of the first root note and the first chord type constituting each chord assigned to each of the plurality of chord designation buttons 3A to 3I according to a predetermined rule. be. In this embodiment, the change method is classified into the following three.

(a) First change method In the first change method, by adding a second chord type to a first chord type, or by replacing the first chord type with a second chord type , to change the allocation state. The second chord types are assigned to the chord designation buttons 3A to 3I when the assignment state is changed by the first changing method. As for the cases of "addition" and "replacement", if the first chord type and the second chord type are compatible, the second chord type is added to the first chord type, and if not, the second chord type is added to the first chord type. If so, replace the first chord type with the second chord type. Even when the first chord type and the second chord type are compatible, the first chord type may be replaced with the second chord type.

For example, if the chord name indicating the chord to be changed is "Am" and "M7" or "aug" is specified as the second chord type, the first changing method uses the first chord type By adding to "m" the characteristics of the constituent notes designated as the second chord type ("M7"), or by taking the first chord type "m" as the second chord type ("aug") A new chord (addition: "Am"→"AmM7" or replacement: "Am"→"Aaug") is changed by replacing with the specified characteristic of constituent notes. In this embodiment, as a first change method, nine chord change buttons 4A to 4F, 4I to 4K are provided with "m7", "aug", "7", "M7", "6", and "9". , “O” (dim7), “7sus4”, and “Φ” (m7 ^♭5 ), respectively.

(b) Second change method In the second change method, when the first chord type corresponds to the third chord type, the first chord type is changed to the fourth chord type different from the third chord type. When the first chord type corresponds to the fourth chord type, the assignment state is changed by replacing the first chord type with the third chord type. The chord designation buttons 3A to 3I are assigned the third chord type and the fourth chord type when the assignment state is changed by the second changing method.

For example, if the chord names indicating the chords to be changed are "C" and "Am", and "M" is specified as the third chord type and "m" as the fourth chord type, the second In the change method, the third chord type and the fourth chord type are exchanged to change to new chords ("C"→"Cm" and "Am"→"A"). In this embodiment, as the second change method, the chord change button 4H is assigned with the third chord type "M" and the fourth chord type "m".

(c) Third Modification Method In the third modification method, the assignment state is modified by adding an accidental symbol (eg, #, ♭, etc.) to the first root note. Chord designating buttons 3A to 3I are assigned change symbols when changing the assignment state by the third changing method.

For example, if the chord name indicating the chord to be changed is "C" and the accidental symbol "#" or "♭" is specified, in the third changing method, the accidental symbol is added to change to a new chord (“C”→“D ^♭ ” or “C”→“C ^♭ ”). In the present embodiment, as the third change method, the chord change button 4G is assigned a change symbol "#".

In FIG. 2, for the sake of explanation, the eleven chord change buttons 4A to 4K are labeled with the above change methods.
