Op. 40. Duration 22 minutes. Schott Music - Digital #Q6332. Published by Schott Music - Digital (S9.Q6332). Key: C minor.With this double concerto, the Reger pupil Johanna Senfter (1879-1961) is entirely in the tradition of Antonio Vivaldi and J.S.

This first edition takes account of all autograph sources. A welcome addition to the repertoire of double concertos with string orchestra.
