Cascades. That's the first word that comes watching this 5843-note MIDI: the impromptu opens on descending arpeggios that stream from hand to hand, minor and hesitant at first, until A-flat major light settles in. At the center, a passionate C-sharp minor trio reminds you that in Schubert tenderness is never far from torment.
The cascades return throughout, and that's your luck: one single gesture to perfect, reused a hundred times. The hand must wheel around the thumb without a bump. Once that motion is in place the piece nearly plays itself, and the trio will ask more of your heart than your fingers.
