En un compás sencillo como 2/2 ó 4/4, las corcheas se barran de forma
predeterminada como dos grupos de cuatro.

Utilizando un macro que seobreescribe el comportamiento automático del
barrado, este fragmento de código cambia el barrado a pulsos de negra.

In a simple time signature of 2/2 or 4/4, 8th notes are beamed by
default as two sets of four.

Using a macro which overrides the autobeaming behavior, this snippet
