Cypher, for solo trumpet, is one of a series of works focusing on subtle ratios of time and the goal of obscuring the perception of 1:1.  These ratios (for example – 1:1, 7:6, 5:4, 4:3, 3:2, 5:3, 7:4, 11:6, 2:1; or 12:12, 14:12, 15:12, 16:12, 18:12, 20:12, 21:12, 22:12, and 24:12) are approached by means of a loose system of situation based rules.  Cypher – a secret method of writing, as by transposition or substitution of letters, specially formed symbols, or the like; writing done in such a method; a coded message; or the key to a secret method of writing.

Cypher was composed with Grace an algorithmic composition environment by Taube.
