I was so thrilled to find this duo that I put it into Finale. There are a significant number of errors in the parts (measures are missing, and there are occasional obvious wrong notes). I managed to puzzle everything together, and will upload the engraved score and a digital "performance," which I hope that the administrators will approve. I'm sure that this piece has NEVER been played. This is quite a find. I believe that Titz was a major "player" in the world surround Haydn, and could have even been an influence on him.
