Maybe the answer to the Minuet in G played by Paderewski.

In reading more on Paderewski..(liner notes included with CD) apparently Paderewski felt secure only after practicing 17 hours a day...even in his "prime."   

This might explain the reason his fingers flew ....Can you imagine it?..Poor fingers beaten into a frenzy with so much practicing.   If he so much as looked at them sideways ..they probably took off at break neck speed..for fear of more Czerny.   

tra la.   ...(the octave passage seems harsh...Ive noticed that Hoffman sometimes hammerred the base notes presumably for "affect." )
