I don't have the docs in front of me at the moment, but I'm sure this is mentioned. It *should* be that it follows the "closest note within a fourth" rule. And the "fourth" can be perfect, augmented, or diminished. So: c fes c f c fis All go up. In each case the closest f(es, is) is some sort of fourth above c. In these cases: c gis c g c ges All go down because g(es, is) is some sort of fourth below c. I just woke up, I hope I'm making sense. -David _______________________________________________ Lilypond-user mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/lilypond-user
