Quartetto Apeiron

The guitar consists of six strings of equal length but differing gauge. This produces six unique pitches that can be altered according to an equal-tempered 12-tone scale by changing the length of the string via the frets.

In this piece only one string is used and the option to change its length is neglected in order to facilitate full exploration of the harmonic and timbral potential of a plucked string under tension. This creates the requirement for all harmony to be based on timbral anomalies and natural harmonics and additionally inspired the periodic re-tuning of each guitar to create microtonally variant fundamentals and other unpredictabilities along the way.

It is an exercise in reducing the instrument to its most barren form. It is the sound a guitar inevitably makes, whether you want it or not. It is my attempt at a portrait of the guitar itself.
