His first" livre d'orgue" is the earliest surviving published collection with traditional French organ school forms( a collection by Louis Couperin that is in manuscript does not seem to have been published.
See Guy Oldham," Louis Couperin: A New Source of French Keyboard Music of the Mid- 17th Century", Recherches sur la musique française classique, Vol. I( 1960), pp. 51–59).
Nivers's other music is less known; however, his treatises on Gregorian chant and basso continuo are still considered important sources on 17th century liturgical music and performance practice.

Whether he composed or not is unknown; a single dance movement survives, attributed to him, in the so- called Manuscrit Vaudry de Saizenay.
His name became well known in the late 20th century, for after his sudden death( he fell down a flight of stairs) as many as four major composers wrote" tombeaux" in his memory: lutenists Denis Gaultier and François Dufaut, and harpsichordists Louis Couperin and Johann Jakob Froberger.
