Publisher: Wiener Urtext Edition
Per Pianoforte

This edition brings all Impromptus and Moments Musicaux together in one volume. The musical text of the 'Impromptus' is based primarily on the composer's autographs as well as on a copy of the Witteczek-Spaun Collection which was very important to Schubert. As no autograph sources for the 'Moments musicaux' exist, the first and early editions of individual pieces were used as reference material.
Due to this  research these editions are very precise, not only with regard to musical details but also with fundamental issues like the position of repetition signs.
This edition also features new notes on interpretation by Robert D. Levin, based on notes from early performances.
