Definition of diminished scale in English English dictionary
(Muzik) The diminished scale is a musical scale the pitches of which ascend in alternating whole tones and semitones. It is called the diminished scale because it can be conceived as a combination of two interlocking diminished seventh chords, just as the augmented scale can be conceived as a combination of two interlocking augmented triads. In classical theory, in contradistinction to jazz theory, it is more commonly called the octatonic scale, although there are forty-two other non-enharmonically equivalent, non-transpositionally equivalent eight-tone sets possible. The term ("octatonic pitch collection") was introduced by Arthur Berger in 1963 (van den Toorn 1983)
