The C Pomeroy 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 five black keys: Db, Eb, Gb, Ab, and Bb and two white keys: C, and Fb. This combination makes this scale - as well as the C Prometheus, C Prometheus Liszt, and C Prometheus Neapolitan - as great choices for composing or improvising music.
If we take a look a the key signature of the C Pomeroy Scale we can find it has six flats and no sharps. Therefore, on sheet music you will find six accidentals on the score. The notes of this scale are: C, Db, Eb, Fb, Gb, Ab, and Bb.
