I just consulted one of the two feathered beams I’ve written this century.
I was initially a bit baffled about the number I had chosen. It turns out
that number is just for MIDI playback (correct me if I’m wrong) and you
just put the notes inside a tuplet and omit the number. For typesetting
purposes the total length of the unaltered notes is what counts:
\version "2.18.2"
\relative d {
\clef bass
\time 4/4
d2 e4~
\override Beam.grow-direction = #RIGHT
\featherDurations #(ly:make-moment 3/4)
{
\once \override TupletNumber.stencil = ##f
\tuplet 5/4 { e16 [ dis-. ais-. fis'-. d-. ] } |
}
\revert Beam.grow-direction
cis1 |
}
