While he was still in Bonn, perhaps in 1792 the year he departed for Vienna, Beethoven wrote this Duo for Violin and Violoncello. It is not known whether he ever completed his work as only the beginning of a fast sonata movement has survived. It is on a page in a collection of sketch leaves that is today known as the “Kafka Miscellany”. Robert D. Levin has completed this fragment in the same style and thus for the first time it is in a version that can be performed. Henle’s edition contains two performance scores of this lively showpiece, thus guaranteeing an optimal duo experience. A welcome addition to the repertoire!
