<H2>Groupettes</H2>
<P>Duration numbers can have any integral value; for instance,</P>
<PRE><TT> !time "4/4"
5cdefg/ </TT>
</PRE>
<P>would encode a measure of <I>5 in the time of 4</I> quarter notes. However,
specification of arbitrary rhythmic groupings in this way is at best awkward.
Instead, arbitrary portions of the score section may be enclosed in <I>groupette
brackets</I>. The durations of all notes inside groupette brackets will
be multiplied by a fraction <I>n/d</I>, where the musical meaning is <I>d</I>
in the time of <I>n</I>. Assuming <I>d</I> and <I>n</I> here are integers,
groupette brackets may take these several forms: </P>
<PRE><TT> {d:n: .... :} d in the time of n
{d:: .... :} n will be the largest power of 2 less than d
{: .... :} d=3, n=2 (normal triplets) </TT>
</PRE>
<P>It can be seen that the second and third form are abbreviations for
the more common kinds of groupettes. (Observe the punctuation of each form
carefully.) Groupettes may be nested to a reasonable depth. Also, groupette
factors apply only after the written duration is carried from note to note.
Thus, the following example is a correct specification for two measures
of 6/8 time: </P>
<PRE><TT> !time "6/8" 8cde {4:3: fgab :} / crc 4.c / </TT>
</PRE>
<P>The notes inside the groupette are <I>4 in the space of 3</I> 8th notes,
and the written-8th-note duration carries normally into the next measure.
This closely parallels the way groupette brackets and note durations interact
in standard notation. </P>
