In publishing the recorder volumes of the Répertoire series the editor seeks to provide music students with a collection of pieces from different eras written for, transcribed for or easy to play on recorders. The volumes 'a' (Z 14132 and Z. 14168) contain solos and duets, the volumes 'b' (Z. 14216 and Z. 14217) contain solos with accompaniment, as well as works for trio sonata scoring.
