| 7 Beat grouping within a bar is controlled by the default grouping |
| 8 established in @code{beamSettings}. This grouping can be established |
| 9 by the use of @code{\\overrideBeamSettings}. Alternatively, the |
| 10 Scheme function @code{set-time-signature} can be used to both |
| 11 set the time signature and establish the default grouping rule. |
| 12 @code{set-time-signature}, takes three arguments: the |
| 13 number of beats, the beat length, and the internal grouping of beats in |
| 14 the measure. If the @code{Measure_grouping_engraver} is included |
| 15 in one of the display contexts, measure grouping signs will be |
| 16 created. Such signs ease reading rhythmically complex modern music. |
| 17 In the example, the 9/8 measure is grouped in two different |
| 18 patterns using the two different methods, while the 5/8 measure |
| 19 is grouped according to the default setting in |
