Hi Steph, I'm not an expert with the \featherDurations interface, but this:

So if you wanted the first note to be a sixteenth and the last to be an eighth, you'd use "2/1". I don't know how you'd get six sixteenths to fit within the duration of a half note, though, as the feathered interface doesn't seem to account for tuplet-like durations. Or, at least, it doesn't seem to be documented. Maybe you'd have to nest one inside the other? Something like ------------------ \tuplet 6/8 { \once \override Beam.grow-direction = #LEFT \featherDurations 2/1 { d16[-. d-. d-. d-. d-. d]-. } } ------------------ (the stickler in me would complain that tuplets should always indicate a shortening of length, and this is technically putting six sixteenths in the space of eight, but I guess the feathering overrules that) Anyway, maybe that helps? Cheers, A
