Hi David, > What duration is equal to 1/20th of a whole note in LilyPond?
This works as expected: { \time 1/4 \tuplet 5/4 { c''16 16 16 16 16 } \time 1/20 \tuplet 5/4 { c''16 } \time 1/4 \tuplet 5/4 { c''16 16 16 16 16 } } The denominator of a #'note-denom time signature would look like this: Hope that helps! Kieren.
