... So it's a 5 *beat* clave pattern, done within (1)
four beat measure, instead of spreading it over 2 measures.Wrkinit



On all the latin styles, like Guaguancó, Cha Cha, Guaracha, Rumba...,the clave is a rhythmic figure that always extends over two bars.

By example, the "2-3" clave:

on the first bar, Quarter Note rest/ Quarter Note/Quarter Note/Quarter Note rest/

on the second bar, Quarter Note with dot/ Quarter Note with dot/ Quarter Note/

The four chords by bar limit on Band in a box not allow you to reproduce the clave in one bar.
