DUNSTABLE, JOHN
(c. 1390, England – 24 December 1453)
Composer who is most frequently cited in continental music theory as the one responsible for bringing the "English sound" to European polyphony, that is, a texture governed by a strict syntax of consonance and dissonance treatment and greatly simplified rhythmic patterns as compared to the French polyphony of the late 14th century. He is also credited, along with Leonel Power, with the earliest cantus firmus mass, the Missa Rex Seculorum (c. 1420s–1430s), although the attribution is not certain. Besides one other cyclic mass, there are 22 single mass ordinary movements, 15 isorhythmic motets, and 27 other settings of Latin texts.
