paragraph_text: Improvisation stands at the centre of Chopin's creative processes. However, this does not imply impulsive rambling: Nicholas Temperley writes that "improvisation is designed for an audience, and its starting-point is that audience's expectations, which include the current conventions of musical form." The works for piano and orchestra, including the two concertos, are held by Temperley to be "merely vehicles for brilliant piano playing ... formally longwinded and extremely conservative". After the piano concertos (which are both early, dating from 1830), Chopin made no attempts at large-scale multi-movement forms, save for his late sonatas for piano and for cello; "instead he achieved near-perfection in pieces of simple general design but subtle and complex cell-structure." Rosen suggests that an important aspect of Chopin's individuality is his flexible handling of the four-bar phrase as a structural unit.

paragraph_text: All of Chopin's compositions include the piano. Most are for solo piano, though he also wrote two piano concertos, a few chamber pieces, and some songs to Polish lyrics. His keyboard style is highly individual and often technically demanding; his own performances were noted for their nuance and sensitivity. Chopin invented the concept of instrumental ballade. His major piano works also include mazurkas, waltzes, nocturnes, polonaises, études, impromptus, scherzos, preludes and sonatas, some published only after his death. Influences on his compositional style include Polish folk music, the classical tradition of J. S. Bach, Mozart and Schubert, the music of all of whom he admired, as well as the Paris salons where he was a frequent guest. His innovations in style, musical form, and harmony, and his association of music with nationalism, were influential throughout and after the late Romantic period.
