Momoko Noguchi (JP)
< \(\pi\) > for solo percussion
Music composition for solo percussion
Audio recorded performance by Kuniko Kato at Hamarikyu Asahi hall, Tokyo, March 2008
The number \(\pi\) is the muse of this solo for percussion composed by Japanese artist Momoko Noguchi. This composition is based on the succession of digits of \(\pi=\)3,141592653589793…
In this recorded performance, the musician plays a progression of \(\pi\) while moving inside a circle composed of 6 different percussion instruments.
Each new digit of \(\pi\) gives the number of notes to play before moving on to the next instrument.
When it is between 1 and 9, this digit corresponds to the number of sounds to play. The digit 0 is replaced by a hit on the bass drum placed in the center of the circle.
After 762 decimal places of \(\pi\), the remarkable sequence 999999 appears. The work is a musical transcription of these first 768 decimals. Since the sequence 999999 appears in the decimals of \(\pi\), what about 333333 or 123456789 or any other sequence I like?
It is conjectured that \(\pi\) is a disjunctive number, that is, a real number in whose decimals any finite-length sequence of digits can be found.
