He formed a string quartet and gave concerts with it and as a soloist.
Schneeberger was the soloist in the premieres of Frank Martin’s violin concerto in 1952, Béla Bartók’s first violin concerto in 1958 and Klaus Huber’s ‘Tempora’ in 1970.
He played a Stradivari violin from 1731 he acquired in 1959 by the luthier Pierre Gerber in Lausanne.
His readings of the six Bach unaccompanied sonatas and partitas (BWV.
1001/6) recorded in 1987 (Jecklin JS 266/7-2) are highly distinguished, both stylistically and expressively.
