88-Musaics

The hidden treasure of the twelve-tone equal temperament

(dedicated to all-fourths guitar tuning community)


Introduction

Logical correspondence between spatial structures and sound structures is what distinguishes regular instruments from the others, in particular the relation "translated spatial structure <--> transposed sound structure".

The relationship (morphism) between translation and transposition is not the only one. The aim of this study is to highlight, with the smallest pre-requisite, the other natural relations between spatial and sound structures.

88 musaics were first discovered by Jean-Yves Fusil (1941- 2011), through analyse geometric patterns in practice of the guitar tuned in fourths (P4 tuning), in Paris (France).
