Barenreiter BA9648 - 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.
