from "44 duos for two violins"

This album contains selected pieces from Bela Bartók's "44 Duos for Two Violins" that are considered suitable to be arranged for violas. With only a few exceptions, most of the pieces have been transposed down by a fifth interval, so that all open strings would correspond to those of the original instruments. Where lowering of the key seemed undesirable and the original key a bit too high for violas, the piece was not included in the album for violas. (P. Bartók)
