## Re: Problem with partial

One common example where people today use it in the middle of a score is repeats, where the repeat sign is in the middle of a bar (especially in combination with prima/secunda volta). Currently, LilyPond doesn't automatically take this into account. Of course, the best solution in this situation would be if LilyPond treated the measure position correctly for repeats.

Hi all,


please note that \partial or \upbeat, whatever you call it, has musicologically a special meaning: the first, incomplete bar, and the last bar of a piece or of a major section of a piece (typically the bar before the next "||" bar glyph) should sum up to a complete bar.


For example, if a song with 4/4 meter starts with "\partial 4 f4", the last bar should, by convention, have a total length of 3 quarter notes. Having said that, you never should use "\partial" or "\upbeat" somewhere within a piece. If lily nevertheless accepts it within a piece without issuing an error or warning, I consider this a bug.


Having a bar within a piece that differs in length from the foreassigned meter is a different concept.

Greetings,
Juergen

IMO, \partial is just fine.  If there's some confusion, by all means we

IMHO using \partial in the middle of a bar is confusing; I think there should be some other command that sets the length of an individual bar. Do you think it would make sense to invent such a command?


I'd rather keep the behavior of \partial -- ie "add an extra X duration to this bar", rather than "this bar should have X duration". That said, I suppose we could rename \partial to \addTime or something like that. I don't think that \upbeat is appropriate, but we could find some other name.
