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: the first two pieces in the first set were published in the composer's lifetime as Op. 90; the second set was published posthumously as Op. 142 in 1839 with a dedication added by the publisher to Franz Liszt. Impromptu No.2 features a melody with chordal accompaniment in the first and last section. The middle section of the Impromptu, marked as a Trio, features continuous triplet motion and has a contrasting character to the main section.
