Compound Time Signatures
In compound meter, subdivisions of the main beat (the upper number) are split into three, not two, equal parts, so that a dotted note (half again longer than a regular note) becomes the beat unit. Compound time signatures are named as if they were simple time signatures in which the one-third part of the beat unit is the beat, so the top number is commonly 6, 9 or 12 (multiples of 3). The lower number is most commonly an 8 (an eighth-note): as in 9
8 or 12
8.

Famous quotes containing the words compound, time and/or signatures:
“Give a scientist a problem and he will probably provide a solution; historians and sociologists, by contrast, can offer only opinions. Ask a dozen chemists the composition of an organic compound such as methane, and within a short time all twelve will have come up with the same solution of CH4. Ask, however, a dozen economists or sociologists to provide policies to reduce unemployment or the level of crime and twelve widely differing opinions are likely to be offered.”
—Derek Gjertsen, British scientist, author. Science and Philosophy: Past and Present, ch. 3, Penguin (1989)
“What a devil hast thou to do with the time of the day? Unless hours were cups of sack, and minutes capons, and clocks the
tongues of bawds, and dials the signs of leaping-houses, and the blessed sun himself a fair hot wench in flame-colored
taffeta, I see no reason why thou shouldst be so superfluous
to demand the time of the day.”
—William Shakespeare (1564–1616)
“So many signatures for such a small heart.”
—Mother Teresa (b. 1910)
