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).
Iceface is related to the Arabic Maqam system, including 9 popular Jins, allowing the creation of multiple Maqamat, including Rast on C and Bayati on A. Those Jins are Ajam on C and G, Ajam Murassa on F, Nahawand on D and A, Rast on C and G, Bayati on D and A, Kurd on E and B, Lami on B, Sikah on Ed and Bd, and Musta’ar on Ad.
A way to generalize Iceface to EDO systems besides 24edo would be starting with the linear diatonic scale of the given temperament for the white keys, and for the black keys, using the note a parachromatic quartertone (usually representing 33/32) beneath the next highest white key, or in other words, black keys should be a white key flattened by half of a pythagorean chromatic semitone. In 31edo, this would be:
! 31IceFace.scl ! 31edo Generalized Iceface Tuning 12 ! 154.84000 193.55000 348.39000 387.10000 503.23000 658.06000 696.77000 851.61000 890.32000 1045.16000 1083.87000 2/1
