Okeghem, Or Oekenheim, Jan, a Flemish musician, born about 1430, died about 1513. Most of his life was spent in France, where he held important civil offices under three kings. The invention of the canon and of artificial counterpoint has been attributed to him, but this is an error. His masses, motets, and chansons possess high merit. Pupils came to him from every part of Europe, among them Jos-quin des Prés, Pierre de la Rue, Brumel, Gas-pard, and Verbonnet.
