    texidoc = "Ambituses indicate pitch ranges for voices.

By default, the ambitus grob is put before the clef.  You can control
this behaviour through the @code{breakAlignOrder} property of the score
context by redefining the order.


The shape of the note heads to use can be changed via the
@code{note-head-style} property, which holds the glyph name of the
note head.  The vertical line between the upper and lower head can be
switched on or off via the @code{join-heads} property.
