-Most automatic beaming settings for a time signature contain an
+Many automatic beaming settings for a time signature contain an
entry for @code{beamExceptions}. For example, 4/4 time tries to
beam the measure in two if there are only eighth notes. The
@code{beamExceptions} rule can override the @code{beatStructure} setting
The workaround for these problems is to manually beam the last
beam in the voice or score.
+By default, the @code{Timing} translator is aliased to the
+@code{Score} context. This means that setting the time signature
+in one staff will affect the beaming of the other staves as well.
+Thus, a time signature setting in a later staff will reset custom
+beaming that was set in an earlier staff.
+One way to avoid this problem is to set the time signature
+in only one staff.
