More than half of Schubert’s chamber works from 1824 to 1828 feature his preferred instrument, the piano. Yet in none of them does it function as an instrumental accompaniment, being instead an equal participant in a duo or trio chamber format. Especially in solo chamber works written for performance in recitals by befriended virtuoso instrumentalists, Schubert was perfectly willing to adapt the style brillant that flourished between 1820 and 1830. Based on the assumption that Schubert applied the style brillant solely for reasons of economy, his virtuoso chamber music has previously been considered to be of lesser value, mentioned only in passing. More recently, however, his turn to extroverted forms of expression has been described as a deliberate counterfoil to the introverted sublimation of his other ‘late’ works. This chapter considers the Fantasy in C Major (D934) and Variations in E Minor on ‘Trockne Blumen’ (D802) to show how Schubert discovered the sophisticated and outgoing mannerisms of the style brillant; it also discusses the development of ornamented variation techniques as an alternative to thematic development, and how this shift of emphasis between musical substance and figuration seems to anticipate the aesthetics of the Romantic arabesque.
