Notes: C, D, Eb, F, G, Ab, and Bb - Key: C - Origin: Chinese - Category: Octatonic Scales
The C Chiao 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 three black keys: Eb, Ab, and Bb and four white keys: C, D, F, and G. This combination makes this scale - as well as the C Qing Shang, C Qing Yu, and C Quan Ming - as great choices for composing or improvising Chinese music.
If we take a look a the key signature of the C Chiao Scale we can find it has three flats and no sharps. Therefore, on sheet music you will find three accidentals on the score. The notes of this scale are: C, D, Eb, F, G, Ab, and Bb.
