Piano Solo - Digital Download SKU: A0.507444 Composed by Heather Cattanach. 20th Century,Children,Contemporary,Instructional. Score. 3 pages. Published by Heather Cattanach (A0.507444). Dodecaphonic Intermediate Piano Solo. Here’s an accessible introduction to 12-Tone music. You may be surprised by how melodic it actually sounds. A dodecaphonic piece for a constellation with twelve letters in its name, although it was shortened to Pyxis, the Compass from Pyxis Nautica, the Mariner’s Compass. I chose the original Tone Row by drawing from a hat. The original row is: B, C, C#/Db, G#/Ab, A#/Bb, D, E, G, A F#/Gb, F, D#/Eb. The rows are used in the original order, inverted, retrograde, and inverted retrograde, and have been transposed. See the accompanying chart. From “88 Constellations†a collection by Heather Cattanach featuring one piece of piano music for each of the 88 constellations (to match the number of keys on a standard piano). Performance Time 40 seconds. 1 page + chart. (General Instructional, Modern, 20th Century, Repertoire, Recital, Schoenberg).
