Unlike other female composers of the 19th century, Emilie Mayer wrote music in larger forms such as the symphony and opera, as well as songs and chamber works. Although her music was quite widely heard during her lifetime, it was almost forgotten after her death and has only in the 21st century seen some rediscovery. She wrote eight symphonies in all, as well as 15 orchestral overtures. Forty-eight of her works were published, including pieces for piano solo, violin and piano, songs, piano trios, string quartets and quintets, a piano concerto (1850), and a large group for cello and piano.
