Ice-face tuning is a method of performing quarter tones on a standard piano or harp by tuning the black notes or accidentals 50 cents higher than normal. The result is an uneven 12-tone scale that consists of the formula: LsLsMLsLsLM where the L consists of 150 cents, the M of 100 cents, and the s of 50 cents. The scale may be referred to as Ice-face and consists of three sizes of tones. It can be notated as:
C Dd D Ed E F Gd G Ad A Bd B C.
The idea of Ice-face came from Hidekazu Wakabayashi in a dream he had. Wakabayashi claimed that he saw a woman playing a piano that was presumably tuned in the same way that Ice-face is tuned.
"Iced" is a way to refer to a neutral interval to describe the quality it has. Unlike "neutral", iced sounds much less ambiguous and gives the impression that it has a distinct quality rather than just sticking it between major and minor as neutral intervals sound like neither major or minor but in fact have a sound described as "Iced".
Tuning in Scala format:
! Iceface.scl ! Iceface Tuning (all back keys a quartertone up), by Hidekazu Wakabayashi 12 ! 150.00000 200.00000 350.00000 400.00000 500.00000 650.00000 700.00000 850.00000 900.00000 1050.00000 1100.00000 2/1
The scale can be thought of as Mohajira superimposed over a diatonic major scale. >Take for example, C major C D E F G A B C, and combine it with the Mohajira mode "Iced Major" C D Ed F G Ad Bd C. This gives a scale of C D Ed E F G Ad A Bd B C, a 10-element subset of Iceface as described above.
Iceface contains 2 separate Mohajira pitch class sets, one "Iced Major" mode starting on C (C D Ed F G Ad Bd C) and one on Ad (Ad Bd C Dd Ed F G Ad).
