Thanks to Vlada's thinking help off-list, I think I've got it now. sounding transpose is -33 written transpose is +33 Take the remainder of dividing by 12 to strip off the octaves: 33 % 12 = 9 Notation goes up 9 sharps. F## C## G# D# A# E# B# E# == F B# == C F## == G C## == D Respell the remaining three as flats and you wind up with the key of Ab, or down three flats instead of up nine sharps. To get from +9 to -3 you subtract 12. 9 - 12 = -3 So if we were converting a part by hand, the music is written in concert pitch. We set the segment transpose to -33 and we transpose the notation +33, then change the key signature from C major to Ab major. Part written in Ab major at -33 sounds like the original part did in concert pitch before the transformation, but is now legible to the player. I think. The numbers seem logical here with all the 12s, and I think the two parts sound the same. These ultra low notes sound so flatulent I can barely discern their pitches. -- D.
