Stylistically, this anonymous sonata for scordatura violin, which has been preserved in the holdings of the Dresden Court Orchestra, points to the southern GermanAustrian school of violin, and it shows the high level of the art of violin playing in Germany in the late 17th and early 18th centuries. A contemporary, handwritten note on the cover of the music refers to Heinrich Ignaz Franz Biber and there are actually amazing similarities to works by this composer which would suggest that he indeed composed the work. However, a definitive clarification of this question must remain open.
