In autumn 1827 Schubert composed eight "Impromptus" for publication as a complete collection by Haslinger in Vienna. When the plan fell through, Schubert offered his "Impromptus" to Schott as pieces which "could be issued individually or all four together”.

The name of the works probably originated from the publisher Haslinger and Schubert also used it for his collection published later as op. posth. 142. The lyrical-romantic works are suitable for advanced piano students and have the character of sonata movements. Robert Schumann who regarded them as parts of a four-movement sonata, drew attention to the second collection published by Diabelli in 1839 in his review.

For the first time this scholarly-critical Urtext edition presents the musical text of the "New Schubert Edition" in new engraving and with optimum page-turns. The fingering takes essential aspects of performance practice of Schubert’s time as well as performance on the modern concert grand piano into consideration. A detailed foreword, suggestions for performance and notes on the evaluation of the primary sources complete the edition.
