Hi Jonathan,
Im trying to make a slur, or even possibly a gliss into a chord and can’t quite
get it right without getting a warning message. Can anyone provide a way I can
do either of these?
Please try to remove from your examples everything that plays no role
for your problem; otherwise, we have to search for the right parts in a
file containing lots of different stuff.
It turns out that there's a simple cure: Slurs in LilyPond are written
_after_ their corresponding pitches, so it's
c( d e f)
for four slurred notes, not (c d e f).
