and a half note is entered using a @code{2} (since it is a 1/2
note). For notes longer than a whole you must use the
@code{\longa} (a double breve) and @code{\breve} commands.
-Durations as short as 64th notes may be specified. Shorter values
+Durations as short as 128th notes may be specified. Shorter values
are possible, but only as beamed notes.
@c Two 64th notes are needed to obtain beams
controlled by three context properties:
@code{measureLength}, @code{beatLength} and @code{beatGrouping}.
These properties may be set in the @code{Score}, @code{Staff} or
-@code{Voice} contexts to delimit their scope.
+@code{Voice} contexts to delimit their scope. The default values
+are set while processing @code{\time} commands, so the @code{\set}
+commands must be placed after all @code{\time} commands.
These determine the beaming as follows:
