MEASURE Ternary or Triple, is that wherein the fall is double to the rise, or where two minims are played during a fall, and but one in the rise. To this purpose, the number 3 is placed at the beginning of the lines, when the measure is intended to be triple; and a C, when the measure is to be common or double. This rising and falling of the hands was called by the Greeks metron and metron. St Augustine calls it plausus, and the Spaniards compas. See ARIS and THEISIS.
