6 Beat grouping within a bar is controlled by the default grouping
7 established in @code{beamSettings}. This grouping can be established
8 by the use of @code{\\overrideBeamSettings}. Alternatively, the
9 Scheme function @code{set-time-signature} can be used to both
10 set the time signature and establish the default grouping rule.
11 @code{set-time-signature}, takes three arguments: the
12 number of beats, the beat length, and the internal grouping of beats in
13 the measure. If the @code{Measure_grouping_engraver} is included
14 in one of the display contexts, measure grouping signs will be
15 created. Such signs ease reading rhythmically complex modern music.
16 In the example, the 9/8 measure is grouped in two different
17 patterns using the two different methods, while the 5/8 measure
18 is grouped according to the default setting in
19 @file{scm/beam-settings.scm}:
21 doctitle = "Conducting signs, measure grouping signs"
27 \overrideBeamSettings #'Score #'(9 . 8) #'end #'((* . (2 2 2 3)))
28 g8 g d d g g a( bes g) |
29 #(set-time-signature 9 8 '(4 5))
30 g8 g d d g g a( bes g) |
37 \consists "Measure_grouping_engraver"
