At the end of his short life, Franz Schubert impressively illustrated, in his collections of ''Impromptus'' and ''Moments musicaux'', how lyrical-songlike form could be rendered on the piano. Nothing can be added to these perfectly fashioned masterworks. Thus in the E flat major Impromptu op. 90 no. 2 the player using our Urtext edition can abandon himself/herself to a perpetuum mobile of scurrying eighth-note triplets and at the same time delight in the piece's very demanding playing technique and sound-world.
