La fonction @code{\\partCombine} prend deux expressions musicales
contenant chacune une partie et les distribue dans quatre contextes
@code{Voice} nommés « two », « one », « solo » et « chords » selon le
moment et la manière dont ces parties fusionnent en une voix commune.
Les voix issues de @code{\\partCombine} peuvent disposer de leurs
propres propriétés de mise en forme définies de manière habituelle. Sont
ici définies des extensions à @code{\\partCombine} de sorte à faciliter
le placement de quatre voix sur une seule portée.

The @code{\\partCombine} function takes two music expressions each
containing a part, and distributes them among four @code{Voice}s named
@qq{two}, @qq{one}, @qq{solo}, and @qq{chords} depending on when and how
the parts are merged into a common voice.  The voices output from
@code{\\partCombine} can have their layout properties adjusted in the
usual way.  Here we define extensions of @code{\\partCombine} to make
it easier to put four voices on a staff.

alto = { fis4 | e8 fis gis ais b4 b | b ais fis2 }
