Abstract

A musical notation system is provided wherein equal sized pitch intervals are represented by equal sized vertical displacements on a musical staff irrespective of the key or transportation of a musical sequence. A clef symbol and diatonic scale indicators are used to indicate the positions of diatonic pitches on the staff. A moveable Do solfa system is preferred so that musical sequences remain unchanged under transposition. The staff is easily adaptable to display various equal tempered (ET) subdivisions of the octave including 12-ET, 17-ET and 19-ET tuning systems. A system of chord notation and an isomorphic transposing keyboard is also described and claimed.
