A notational system in which the pitch of notes is perceived from their apparent planar relationship projected upon a staff just as the shape of a constellation is perceived by the stars' apparent planar relationship projected upon the earth. A person in a far off galaxy would see the same stars but different shapes or constellations. As the group of notes rotates it produces different melodies or contonations which can be used as new motifs for composition in the way that the serialists used transposition, inversion and retrograde inversion et cetera.
