Notes: C, Eb, E, F, G, A, and Bb - Key: C - Origin: African - Category: Octatonic Scales
The C Bluesy R and R 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: Eb, and Bb and five white keys: C, E, F, G, and A. This combination makes this scale - as well as the C Blues Nine-Note, C Blues Enneatonic, and C Blues Heptatonic - as great choices for composing or improvising African music.
If we take a look a the key signature of the C Bluesy R and R 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, Eb, E, F, G, A, and Bb.
