Suite for Microtonal Piano
From Wikipedia, the free encyclopedia
Suite for Microtonal Piano is a suite for specifically microtonally tuned piano(s) by Ben Johnston written in 1977 (see also just intonation).
"The piano is tuned to a selection of overtones from the fifth octave of the harmonic spectrum of C. All octaves are tuned in the same scale....The lowest C (33 Hz.) can be used to tune the scale by ear. In succession, touch the nodes producing the 3rd, 5th, 7th, 13th, 17th, [and] 19th partials. Then G, D; D, A; E,b; [and] B-flat, F; are just (beatless) fifths."
[edit] Movements
- Alarum
- Blues
- Etude
- Song
- Toccata
Alarum is a Shakespeare era stage direction indicating "a grand entrance" and an archaic word for a call to arms, so "Alarum" is a fanfare.
"Blues" and "Song" are both slow movements. "Blues" uses as blue notes the minor seventh (C-Bb) and mediant (in D dorian exactly halfway between E and G). "Song" is in E phrygian.
"Etude" is a study in serial technique and six-against-five polyrhythms in which Johnston indicates "blur with pedal". This, "clues us in that the linear intricacies are only part of the story here: the amazing swirl of overtones resulting from an atonal application of this tuning are of equal importance." (Bush 1997)
"Toccata" features diatonic outer sections and a spikier chromatic middle section.
