Abstract
In a chord progression input/modification device, when a key and a single or two successive reference chords are designated by a user, available chords are acquired and displayed. Any one of the available chords can be used, in consonance with musical theory, to follow or substitute for the single reference chord, or to be inserted between the two reference chords for generating a modified chord progression. The chord progression modification device may be installed in an electronic musical instrument.
Claims19
A chord progression input/modification device comprising:
- means for obtaining a reference function chord corresponding to a reference chord designated by a user,
- acquisition means for acquiring a group of suitable following function chords which can follow the reference function chord in consonance with musical theory, and
- means for obtaining at least one of a plurality of triads, basic chords and tension chords corresponding to each function chord in the group of suitable following function chords as a group of suitable following chords.
A chord progression modification device comprising:
- means for obtaining a first and a second reference function chord corresponding to a first and a second successive reference chord, respectively, designated by a user,
- a first acquisition means for acquiring a group of suitable following function chords which can follow the first reference function chord in consonance with musical theory,
- a second acquisition means for acquiring a group of suitable preceding function chords which can precede the second reference function chord in consonance with musical theory,
- a third acquisition means for acquiring a group of suitable function chords to be inserted, which are commonly included in both of the groups of suitable following and preceding function chords, and
- means for obtaining at least one of a plurality of triads, basic chords and tension chords corresponding to each function chord in the group of suitable function chords to be inserted as a group of suitable chords to be inserted between the first and second successive reference chords.
A chord progression modification device comprising:
- means for obtaining a reference function chord corresponding to a reference chord designated by a user,
- acquisition means for acquiring a group of suitable substitute function chords which can be used in place of the reference function chord in consonance with musical theory, and
- means for obtaining at least one of a plurality of triads, basic chords and tension chords corresponding to each function chord in the group of suitable substitute function chords as a group of suitable substitute chords.
A method for modifying or inputting a chord progression, the method comprising the steps of:
- obtaining a reference function chord corresponding to a reference chord designated by a user,
- acquiring a group of suitable following function chords which can follow the reference function chord in consonance with musical theory, and
