Klaviersonate a-Moll op. post. 143 D 784

Franz Schubert’s Piano Sonata op. 143 in a minor was composed in 1823 after his large “Wanderer Fantasy”. With its formal cohesion and mature originality, this a-minor Sonata initiated a new phase in Schubert’s sonata oeuvre. The composer dispensed here with all pianistic brilliance. At the same time, a wealth of colour and of sonorities triumphs in such a manner that the work numbers among Schubert’s most frequently played sonatas. For this Urtext edition, we had at our disposal the composer’s autograph as the authoritative source; the posthumous first edition was consulted only by way of comparison.
