Noted as one of the most important violin pedagogues of the 19th century, Mazas was not afraid to challenge his students to become stronger players. These 15 pieces constitute Mazas’ thoughts on the ABCs of playing violin duets where the objectives are to develop ensemble playing, musicianship, and technical ability in young players. The “violin 1” part features the greater of the musical interest while the “violin 2” part acts as an accompaniment. A great opportunity for teachers who want their students to learn how to play in a duet setting.
