The period spanning the deaths of Beethoven and Chopin provides a time frame for a discussion of the works of composers active in the late 1820s and early 1830s: Chopin, Liszt, Berlioz, Mendelssohn-Bartholdy, Bellini, Meyerbeer, and Schumann. During this period, composers explored new paths in terms of form—in particular the fragment—and its relation to literature and nature. Character pieces, the lied, the symphony, and the opera are some of the genres that underwent substantial change or appeared as entirely new forms.
