'toward the continuum' — a composition of a modern author Dolores Catherino for a music instrument that uses 106 intervals in an octave

polychromatic music uses intervals less than 1 semitone (1 tone=1 note, 1 semitone = 1/2 note). this notation system consist of not only note & alteration symbols, but also colour (from red to violet) to express the current pitch of a note in cases when intervals are very small (for example 1/64, 1/72, 1/106)
