He played in various chamber music ensembles: the Marsick Quartet (with whom he had a three-month tour in Cairo[1] and around in 1909), the Gaspard Quartet (1910–1920),[B 2] the Thibaud[5] – Arthur – Rosoor Trio (1909–1933), the Quartet of Bordeaux (1936–?)[B 3] as well as with Francis Planté, in duo, trio with Noëla Cousin playing violin and in Piano quartet with also Marie-Valentine Rosoor, his wife, playing viola (1921–1927).[6]
He gave quite a number of concerts, most in Bordeaux[7] and around (e.g. in Arcachon[A 2] from 1910 to 1926) including in northern Spain, but also a few in Paris. He was one of the earliest performers of pieces like Debussy's sonata,[8] Fauré's second sonata or Vincent d'Indy's trio, all rehearsed with their composers.[9]

He played a Testore cello at the beginning of his career[C 2] and, later, a Gigli ; occasionally[20] a Tecchler.
