De la misma forma, se pueden comprimir por una fracción trozos de
música más largos, como si cada nota, acorde o silencio tuviera la
que lo hace es:
@example
-\compressMusic #'(@emph{numerador} . @emph{denominador}) @{ @emph{música} @}
+\scaleDurations #'(@emph{numerador} . @emph{denominador}) @{ @emph{música} @}
@end example
@noindent
% Normal durations
<c a>4 c8 a
% Scale music by *2/3
-\compressMusic #'(2 . 3) {
+\scaleDurations #'(2 . 3) {
<c a f>4. c8 a f
}
% Scale music by *2
-\compressMusic #'(2 . 1) {
+\scaleDurations #'(2 . 1) {
<c' a>4 c8 b
}
@end lilypond
selon le cas en utilisant @code{timeSignatureFraction} pour obtenir la
division adéquate pour chaque portée. Les durées, dans chacune des
portées, seront alors échelonnées par rapport à la métrique commune.

You can alter the duration of single notes, rests or chords by a
fraction @code{N/M} by appending @code{*N/M} (or @code{*N} if
@code{M} is 1) to the duration.

Longer stretches of music may be compressed by a fraction in the
