Notes: C, Db, D, F, G, Ab, and A - Key: C - Origin: Japanese - Category: Octatonic Scales
The C In uses eight notes per octave. Because of this same reason it is a member of the so called Octatonic -scales that have Eight-note (or Eight-tone). On the piano keyboard, it is made up of two black keys: Db, and Ab and five white keys: C, D, F, G, and A. This combination makes this scale - as well as the C Akebono I, C Akebono II, and C Banshikicho - as great choices for composing or improvising Japanese music.
If we take a look a the key signature of the C In Scale we can find it has two flats and no sharps. Therefore, on sheet music you will find two accidentals on the score. The notes of this scale are: C, Db, D, F, G, Ab, and A.
