The date of composition of Arnold Trowell's Viola Sonata is not known with any precision, however, Trowell was the cellist in Lionel Tertis's group The Chamber Music Players in 1922 and the early part of 1923, so it was most likely composed sometime around that period. There is nothing documented about a performance of the work by Tertis, and John White's book on Tertis mentions the Sonata only as being associated with Tertis. The manuscript was in the hands of Robert Scott (https://www.oks.org.uk/news/remembering-robert-scott/) for several decades, from sometime in the eighties. He produced a manuscript copy of the Sonata with some passages written out in a different key signature, with the goal of simplifying some of the enharmonic spellings.
