I'm not sure what you are after and maybe what follows is as obvious to you as
it is to me, but in case it isn't here I go:
For easier reference I'll repost one of Harm's examples:
\relative d {
\clef bass
\override Beam.grow-direction = #RIGHT
\featherDurations #(ly:make-moment 3/4)
c16*4/3[ d e]
c32*2*4/3[ d e]
c64*4*4/3[ d e]
c128*8*4/3[ d e] |
\revert Beam.grow-direction
cis1 |
}
c16/c32/64/128 means 2/3/4/5 feathers respectively
Each group is expected to last one quarter note which is denoted by "4".
Since we start with a 1/16th we have to mutliply by 4 to get back to 4.
There are 3 notes in each group which means we add the notelength 3 times which
is another way of saying we multiply by 3. Hence we have to divide by 3 to make
the whole group 1/4 note in length again.
A very similar argument goes for c32 (*2 == c16), c64 (*4 == c16) and c128 (*8
== c16).
If you were looking for something else when you asked for the math then please
be more specific.
Kind regards,
Michael
