Mix five (a)
For solo clarinet
Listen
Composed in 2006 for Dimitri Ashkenazy, Mix Five (a) for solo clarinet mixes five different musical ideas (distinct but partially related) with differing lengths governed by the Fibonacci number series in a systematic linear order. The following diagram shows this order or formal structure of the piece, where letters signify the different ideas and numbers indicate length of measures:
| a3 | b2 | |||
| a5 | b3 | c2 | ||
| a8 | b5 | c3 | d2 | |
| a13 | b8 | c5 | d3 | e2 |
| a2 | b13 | c8 | d5 | e3 |
| c13 | d8 | e5 | ||
| d13 | e8 | |||
| e13 |
