I mean that it is documented behaviour. The NR says "When \partial is used at the beginning of a score, duration is the length of the music preceding the first bar." > I admit that I wondered more than a bit about the requirement in the > Notation Reference to insert a \partial "when the time signature > changes in mid measure".

It used to be the case that you had to use a different (more complicated) syntax to do that, but since the functionality was quite similar to partial, partial was updated to work when used at times other than the beginning of a piece. > > All of the examples of \partial in the documentation use it at the > > beginning of a bar and supply the duration.

What > are you suggesting to do when the composer did not intend nor supply > an upbeat? (My example is from C.Ph.E. Bach (1714 - 88): Fantasia C > major H.291, bars 71 - 72.) Partial only inserts an upbeat when used at the beginning of a score. To quote the NR: "When \partial is used after the beginning of a score, duration is the remaining length of the current measure. It does not create a new numbered bar." You should imitate the examples in the NR: put \partial 2 at the beginning of the shortened measure. Something like this (based on the image you attached): \relative { \time 3/4 g'8( fis e' d c b) \partial 2 a4( gis) \bar "||" \tempo "Presto di molto" \time 2/4 R2 } Kevin _______________________________________________ bug-lilypond mailing list bug-lilypond@gnu.org https://lists.gnu.org/mailman/listinfo/bug-lilypond
