Dodeka music notation
The Dodeka Music Notation is an alternative music notation or musical notation system invented and designed in 1980s by inventor and musician Jacques-Daniel Rochat in an attempt to improve upon traditional music notation. Staff and pitch Unlike conventional musical notation, the Dodeka music notation system uses a chromatic scale of 12 pitches and follows an equal pitch intervals configuration, with 4 lines per octave. In this configuration, the 12 notes of an octave appear in four positions vis-à-vis the staff lines, that is, either on, between, above and below the lines. Each pitch has its own unique place on the staff. And while conventional music notation may alter notes using accidental signs or key signatures, notes in the Dodeka notation appear as they are. There are no more key signatures or accidental signs in this musical system. Note duration The Dodeka notation system represents note duration in a visual manner. Note lengths are represented through the notes graphical shapes, similar to what can be found in sequencer programmes. The reference time unit or time value being the quarter note (or crotchet), all durations are expressed as visual ratios from this reference point. For example, a whole note is the representation
