4 Impromptus By Franz Schubert For Solo Piano (1827) Op.90/D899

Franz Peter Schubert (1797 - 1828) was an Austrian composer.

In a short lifespan of less than 32 years, Schubert was a prolific composer, writing some 600 Lieder, nine symphonies (including the famous "Unfinished Symphony"), liturgical music, operas, some incidental music and a large body of chamber and solo piano music. Appreciation of Schubert's music during his lifetime was limited, but interest in his work increased significantly in the decades following his death. Franz Liszt, Robert Schumann, Johannes Brahms and Felix Mendelssohn, among others, discovered and championed his works in the 19th century. Today, Schubert is seen as one of the leading exponents of the early Romantic era in music and he remains one of the most frequently performed composers.

Franz Schubert's 'Impromptus' are a series of eight pieces for solo piano composed in 1827. They were published in two sets of four impromptus each: this first set was published in the composer's lifetime as Op. 90, and the second set was published posthumously as Op. posth. 142.
