Twoset Violin: Passacaglia - Heifetz/Handel/Halvorsen

Twoset Violin performs Passacaglia (Edited Description) Originally on Harpsichord, then on violin and viola, now on just two sets of violins! I think this is transposed for violins by heifetz. Correct me if I’m mistaken. :) Credits to ‪@islamiller40‬ for the idea of this video! (ty!)
