(b before 1650; d Paris, 1719). French organist and composer. He served as organist from the mid-1660s at the royal abbey of Ste Geneviève in Paris and later to the Jacobins in the nearby rue St Jacques. Considered one of the finest organists of his day, Raison was Clérambault's teacher. His two published sets of organ masses (Paris, 1688, 1714) were intended for use in monasteries and convents and contain useful instructions on performance and interpretation; notably, he offered guidance on metre, notes inégales, and fingering.
