paragraph_text: Although Melartin was chiefly a lyricist, the symphony was central to his musical output. He wrote six symphonies (1902–1924) and was the first Finnish composer to bear Mahler's influence. The fourth symphony uses a vocalise like that of Carl Nielsen's "Sinfonia Espansiva". The fifth is a "Sinfonia brevis" ending in a fugue and chorale, while the sixth, harmonically more advanced than the other five, advances stepwise from a C minor first movement – with evocations of Mahler's second symphony – to an E-flat major finale. His musical output also includes an opera, "Aino" (based on the character from the Finnish national epic), a violin concerto, four string quartets, and many piano pieces. His works therefore are divided mainly into large-scale works for orchestra, and chamber pieces for much smaller groups and soloists. Despite working in the same time period as Jean Sibelius he was not influenced by the more famous composer's style, and his work has been largely overshadowed by that of Finland's most revered composer.
