Early American concert music developed between the mid-19th to late-19th centuries. Notable virtuoso performers like Jenny Lind, Ole Bull, and Louis Moreau Gottschalk toured America, helping grow interest in art music. American composers like Anthony Philip Heinrich were among the first to be popular before the Civil War. The Second New England School, centered around Boston, featured composers like John Knowles Paine, Edward MacDowell, and Amy Beach who embraced German ideals of concert music while incorporating American themes. Antonín Dvořák influenced American nationalism during his directorship of the National Conservatory in New York in the 1890s.
