Stephan Zielinski: Dwa

“Revelation tuning” is the tuning system Michael Harrison used for his album Revelation: Music in Pure Intonation.  He describes it at Music In Pure Intonation.

It’s not a chromatic scale, and he picked the specific frequencies to produce perfect fifths (in a 3:2 ratio) and perfect minor sevenths (in a 7:4 ratio.)  If I’ve calculated this correctly, these are the corresponding microtonal adjustments (to a precision of one cent): F 0, F# -27, G +4, G# -123, A +8, Bb -29, B +12, C +2, C# -125, D +6, Eb -31, E +10.

With that in place, a score written this way:
