Seven Sisters is a study in 7/8 time, inspired directly by Etude No.16 by Philip Glass. There are two main motifs that are introduced individually. One low in the bass and the other high in the treble, that are then combined to create some fun crossing the hands back and forth over a driving ostinato based on only two chords. There is plenty of scope for dynamic variation and sensitivity to tonal balance, whilst also playing with energy and imagination.
