text @qq{a2}.
+By default, the partcombiner merges two notes of the same pitch as an
+@notation{a due} note, and separates notes more than a ninth apart into
+separate voices. This can be overridden with an optional argument of a
pair
+of numbers after the @code{\partcombine} command: the first specifies
+the interval where notes start to be combined (the default is zero) and the
+second where the notes are split into separate voices. Setting the second
+argument to zero means that the partcombiner splits notes with an interval
of
+a second or more, setting it to one splits notes of a third or more, and
so one.

Both arguments to @code{\partcombine} will be interpreted as separate
@code{Voice} contexts, so if the music is being specified in relative
mode then @emph{both} parts must contain a @code{\relative} function,
