Kalliwoda, Violin and Viola Duos Op. 208
Mozart composed 12 Duets for Violin and Viola during the Classical period. The solo instruments are stapled, and the score is published by Breitkopf and Haertel (BR.EB-3979). The 16-page score is a delightful blend of the two instruments, with intricate harmonies and melodious tunes. It's a must-have for any classical music lover.
