Vitry, Philippe de

About 1290-1316


French theorist; born at Vitry, Pasde-Calais. He became Bishop of Meaux, where he died. He wrote many treatises on the theory of mensurable music and did much to advance theory and practise. He established the values of the four prolations and invented red notes and proportions. He is given the credit of of first using the term contrapunctus instead of discantus, and brought into general use the notes called minima and semiminima.
