As an electronic musician I've always been fascinated by sine waves. They were present on my first Moog synthesiser as a sound generator option, and when sampling became available in the late 80s I learnt that any sound can be broken down into its constituent sine waves using Fourier analysis, and then reconstructed again. Virtually every sound heard today from any digital device — from HDTV to the iPod — is described as a sum of its sine wave parts in the digital realm.

Sine waves are unique in that they are the only sound in nature not to contain any harmonics beyond their fundamental frequency — they are the vampires of the sound world casting no harmonic shadow or reflections.

The piece of music I wrote for the Geekpop Festival, Sine Language, explores the idea of sine waves, and how they relate to other concepts such as the Western tuning system known as equal temperament, and even to ancient Greek cosmological ideas (listen to Sine Language).
