sonata (n.)
1690s, from Italian sonata "piece of instrumental music," literally "sounded" (i.e. "played on an instrument," as opposed to cantata "sung"), fem. past participle of sonare "to sound," from Latin sonare "to sound," from PIE *swene-, from root *swen- "to sound" (see sound (n.1)). Meaning narrowed by mid-18c. toward application to large-scale works in three or four movements.
