I'm still do not understand the math (I'd like to generate a formula!) for tremolos.
I also remained confused by this for a long time till I understood
that the rules are pretty simple. The thing to keep in mind is that
\repeat tremolo and <note>:<duration> don't work the same.
The rules are:
- The appearance of the notes in a tremolo determines the
total duration. (Even if there are two notes, they count
for this duration once.)
- The beaming of the notes determines the duration of the
notes in the fully developed form where you replace the
tremolo notation with actual repeated notes, like
\unfoldRepeats does.
- The number passed to \repeat tremolo is the number of
times the pattern is repeated.
- In the syntax <note><duration>:<tremolo duration>, the
<duration> is the total tremolo duration, and
<tremolo duration> is the duration of one note in
the developed form.
So your tremolo can be written as
\relative d' {
\time 3/4
d2.:16
}
as William suggested, or
\relative d' {
\time 3/4
\repeat tremolo 12 d16
}
since "duration of dotted half note / duration of sixteenth note = 12".
Best,
Jean
