Comment #22 on issue 2823 by [email protected]: Patch: Fixes position of mensural c clef
http://code.google.com/p/lilypond/issues/detail?id=2823
I have all Ockeghem from Chigi and will make a scan tonight. Prolationum is notated throughout in two parts, but each notated part is a two-part canon. from J�rgen's description it seems to me that he's speaking about the second Kyrie, which is a canon at third, denoted by _two_merged_c-clefs_. IIRC part one has the two clefs on the first and second lines, meaning that it's should be read in both soprano and mezzosoprano clefs. part tow has the clefs on the fourth and fifth line, i.e. its music should be read in tenor and baritone clefs. I also have this (and some other) movement in LilyPond format, it's a really good test for "mensural and modern from same source"; can send it if interested. p
