But ... I have been playing with this piece on Bari for over a year, then I noticed a comment on the YouTube video that Yasuto Tanaka is actually playing the violin score (presumably with the piano transposed accordingly), not a transposed for Eb sax arrangement.
So I am now in the process of transposing the piano part and practicing the violin part. It fits in better with the Bari range - from low A to top E.
I may add this into my plans for a concert later this year!
