"It was a couple of Schubert Impromptus that followed, the C minor and the stream-like E-flat major"
Franz Schubert (1797-1828) was an Austrian composer. He is particularly remembered for his 600 Lieder ('songs') which are compositions written as settings for romantic German poems.
An impromptu, as its name suggests, is a spontaneous musical composition, usually for a solo instrument.
Schubert's Impromptus are a series of eight solo pieces for the piano, composed in 1827. No's 1 and 2 are in C minor and E-flat major respectively.
