This is a discussion of the Fiorillo Etude/Caprice #32. I’m using the International Music Company (IMC) publication, edited by Ivan Galamian (catalog #2178).
Please note: the Texas Music Educators Association (TMEA) says this should be performed at 46-54 to the quarter note. They also stipulate that measures 7 and 15 should be played Bb instead of the printed B natural.
