His operas often contain thematic material based on folksong, and this folk-influenced genre had begun with Weber's Der Freischütz (1821).
He gave the title "Grand Trio" to each of his works for piano, violin and cello, indicative of the importance he attached to them.
Marschner's ability to depict supernatural horror by musical means is especially evident in the first two operas as well as in some of his ballads, such as "Die Monduhr" (c. 1839).
He also wrote a considerable amount of chamber music, including seven piano trios, as well as unaccompanied male choruses that were very popular in the nineteenth century.
Among his operas, Hans Heiling and especially Der Vampyr have been adapted and revived in recent years with considerable success.
