6 There is no default beat structure specified for 7/8 time,
7 so if automatic beams are required the structure must be specified. For
8 example, to group all beams 2-3-2 in 7/8 time, specify the
9 beat structure to be (2 3 2):
11 doctitle = "Beam grouping in 7/8 time"
18 \set Score.beatStructure = #'(2 3 2)
