I was at the library so I read that book. It is a history of notation, not a textbook on how to notate. He does say that the shift to tonal music resulted in: 1) regular use of the natural sign to cancel flat and sharp 2) standardization of the double-sharp and double-flat signs 3) canceling one accidental, before the introduction of another, with natural-flat (after double-flat or sharp) and natural-sharp (after double- sharp or flat) Point 3 says people put a natural between gis and ges in tonal music, if that transition ever happened in tonal music. The only extraNatural Rastall's book is when sharp follows a double sharp. The only example in his book where sharp follows flat (Berg, 1907) is printed without the extraNatural. Maybe the textbooks are silent about the old rule for when gis follows ges, because that happened too rarely to have a standard while the old rules were current. _______________________________________________ bug-lilypond mailing list bug-lilypond@gnu.org https://lists.gnu.org/mailman/listinfo/bug-lilypond
