Score and parts. 4 pages. Nigel Williams #5322701. Published by Nigel Williams (A0.763378). This much loved piano piece by Chopin is also remembered in a version as the classic song I'm Always Chasing Rainbows recorded by Judy Garland in 1917. This string duet arrangement for violin and viola adheres to Chopin's melodic line. The viola provides a gentle rocking eighth-note accompaniment to the violin melody, and the final extended cadence has just a hint of 'Blues'. The performance duration is two and a half minutes and the full score has two individual parts attached. This arrangement is ideal classroom repertoire for High School students working either at home or at school. Enjoy browsing my many string trio, quartet and ensemble arrangements on SMP.
