It would seem that you associate the term "pitch" with physical frequency. That is not how LilyPond uses the term (though indeed the respective "music glossary" entry leaves something to be desired regarding clearing that up). <URL:http://www.lilypond.org/doc/v2.16/Documentation/notation/pitches> A "note" is more than a pitch: it has duration, articulations, etc. Indeed, if I ask the Scheme sandbox: $ lilypond scheme-sandbox GNU LilyPond 2.17.12 Processing `/usr/local/share/lilypond/2.17.12/ly/scheme-sandbox.ly' Parsing... guile> #{ c #} #<Pitch c > guile> #{ c4 #} #<Prob: Music C++: Music((duration . #<Duration 4 >) (pitch . #<Pitch c >) (origin . #<location <string>:2:2>))((display-methods #<procedure #f (note parser)>) (name . NoteEvent) (iterator-ctor . #<primitive-procedure ly:rhythmic-music-iterator::constructor>) (types general-music event note-event rhythmic-event melodic-event)) > guile> It also considers "c" just a pitch (composed from octave, notename and alteration), while "c4" is a complete note. -- David Kastrup _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
