The phrase 'Contenance Angloise' was coined by Martin le Franc in a poem dedicated to Duke Philip the Good of Burgundy (1396–1467) in 1441-2 to describe the distinctive musical style of the era.
Martin le Franc is famous in music history for penning the phrase "la contenance angloise", the English countenance, a much-debated phrase referring to a characteristically English sound found in the music of composers such as John Dunstaple.
