Will be playing this as a solo this year, hoping to get some tips/advice? Tempos for the different variations? Are all 3 variations supposed to be played at the same tempo? Is it best to put a ral at the end of each phrase (2nd vari) to give more time to breath? Any alternate cadenzas? Is the 3rd vari best being more sedate and crystal clear or faster (easier) to hide any blemishes? loads of vib in the melody or play it straighter? etc all tips advice gratefully received!
