Tremolo repeats
Tremolos can take two forms: alternation between two chords or two notes, and rapid repetition of a single note or chord. Tremolos consisting of an alternation are indicated by adding beams between the notes or chords being alternated, while tremolos consisting of the rapid repetition of a single note are indicated by adding beams or slashes to a single note.
To place tremolo marks between notes, use \repeat
with
tremolo style:
\relative c'' { \repeat tremolo 8 { c16 d } \repeat tremolo 6 { c16 d } \repeat tremolo 2 { c16 d } }
The \repeat tremolo
syntax expects exactly two notes within
the braces, and the number of repetitions must correspond to a
note value that can be expressed with plain or dotted notes. Thus,
\repeat tremolo 7
is valid and produces a double dotted
note, but \repeat tremolo 9
is not.
The duration of the tremolo equals the duration of the
braced expression multiplied by the number of repeats:
\repeat tremolo 8 { c16 d16 }
gives a whole note tremolo,
notated as two whole notes joined by tremolo beams.
There are two ways to put tremolo marks on a single note. The
\repeat tremolo
syntax is also used here, in which case
the note should not be surrounded by braces:
\repeat tremolo 4 c'16
The same output can be obtained by adding :N
after
the note, where N
indicates the duration of the
subdivision (it must be at least 8). If N
is 8, one
beam is added to the note’s stem. If N
is omitted,
the last value is used:
\relative { c''2:8 c:32 c: c: }

Cross-staff tremolos
Since \repeat tremolo
expects exactly two musical arguments for
chord tremolos, the note or chord which changes staff within a
cross-staff tremolo should be placed inside curly braces together with
its \change Staff
command.
\new PianoStaff << \new Staff = "up" \relative c'' { \key a \major \time 3/8 s4. } \new Staff = "down" \relative c'' { \key a \major \time 3/8 \voiceOne \repeat tremolo 6 { <a e'>32 { \change Staff = "up" \voiceTwo <cis a' dis>32 } } } >>
