Johan Peter Emilius Hartmann was a Danish composer. Hartmann's works were characterized by artistic seriousness, dramatic vitality, and in particular, by national coloring which appealed deeply to Danish audiences. The Nordic elements, which could be discerned in the themes based on folksongs, modulations, and the tendency towards rather dark sounds, emerged strongly after the 1830s. Hartmann united these Romantic influences with a strong control over both form and theme, acquired through his Classical training and often reminiscent of Felix Mendelssohn.
