The C Hijaz 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: F#, and G# and five white keys: C, D, E#, A, and B. This combination makes this scale - as well as the C Cushak, - as great choices for composing or improvising Armenian music.
If we take a look a the key signature of the C Hijaz Scale we can find it has no flats and three sharps. Therefore, on sheet music you will find three accidentals on the score. The notes of this scale are: C, D, E#, F#, G#, A, and B.
