A Dictionary of Music and Musicians/Compound Time

COMPOUND TIME. A rhythm formed by the combination of two, three, or four bars of simple time. The compound times most used are as follows:—

Compound Common Times.
6-8	formed of	two	bars of	3-8	time.
6-4	"		"	3-4	"
12-8	"	four	"	3-8	"
Compound Triple Times.
9-8	formed of three		bars of	3-8	time.
9-4	"		"	3-4	"

To these may be added 4-4 time, which is made up of two bars of 2-4 time, and in Germany is always classed with the compound times. In England however it is more often called simple time, those rhythms only being considered as compound, in which each beat is divisible into three parts. [See Common Time.]
