 His works were influential in the development of the bassoon and remain a staple of the classical bassoon repertoire.Ozi's "Nouvelle Méthode de basson" (1803) was regarded as one of the first complete instructional materials for the bassoon, which was at the time still seven-keyed, as compared to the far more complex modern instrument.The technical demands of Ozi's literature spurred on its development; instrument maker Carl Almenräder in particular used his compositions to direct further development of the bassoon in his development of the key mechanism.
