Romanticism
Chopin is considered one of the great masters of Romantic music.
Chopin regarded most of his contemporaries with indifference, though he had many acquaintances who were associated with romanticism in music, literature, and the fine arts—many of them via his liaison with George Sand. Chopin’s music is, however, considered by many to epitomise the Romantic style. The relative classical purity and discretion in his music, with little extravagant exhibitionism, partly reflects his reverence for Bach and Mozart.
Chopin never indulged in explicit “scene-painting” in his music, or used programmatic titles. He castigated publishers who renamed his compositions in this way.
