Accent on the Black Keys is a wonderful collection of 10 Gillock originals such as Valse Gaie, On the Champs Elysees, and Hommage to Chopin. It also functions as a theory workbook that will ensure a better understanding of the five major and five minor keys that begin on a black key. The pieces are prefaced with the scale, the chords and cadences in the key, and the student is also required to write in the key signature of each piece.
