Niels Wilhelm Gade: Sonate 2 D-Moll op. 21: Keyboard

"The arrangements for piano four-hands (1865) by August Horn, for violoncello and piano (1866) by Robert Wittmann, for flute and piano (1886) by Karl Müller, and for viola and piano (1895) by Heinrich Dessauer - some of them published by Breitkopf & Härtel during the composer’s lifetime (and certainly with his approval) - bear witness to the popularity and widespread dissemination of the Sonata."
