Suite for Microtonal Piano (1978) is a suite for specifically microtonally tuned piano(s) by Ben Johnston written in 1977 (see also just intonation). According to Bob Gilmore the piece, "take() extended just intonation well beyond the point reached by Harry Partch."〔Johnston, Ben and Gilmore, Bob (2006). ''"Maximum Clarity" and Other Writings on Music'', p.xxxv. ISBN 978-0-252-03098-7.〕 "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, 11th, 13th, 17th, () 19th partials. Then G, D; D, A; E, B; () B-flat, F; are just (beatless) fifths."〔''Microtonal Piano by Ben Johnston'' (1997). Phillip Bush, piano. Koch International Classics 3-7369-2.〕 ==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-B) 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."〔 "Toccata" features diatonic outer sections and a spikier chromatic middle section. The piece has been recorded and released on: *''Microtonal Piano by Ben Johnston'' (1997). Phillip Bush, piano.
