(2πr)/2 + (2r) = L + R

for Solo Piano (2011)

 

The piece takes its inspiration from the ratios found in a half circle. This meant working out the ratio between a half circle's diameter and circumference, which turned out to be 7:11. In addition to informing the title, this led to one hand of the piano part being assigned rhythmic groups of seven, and the other groups of eleven. The piece has a ternary structure, where the B section is in binary form. The opening material establishes the complex rhythmic nature of the two hands of the piano, followed by the B section which consists of two contrasting sections: the first a dance-like section, followed by a slower, more sustained section. The opening material then returns, but treated palindromically.
