Gustav Mahler was a romantic composer from the late 19th and early 20th centuries. He was born in Bohemia, which is now part of the Czech Republic, and was known for his symphonies, choral works, and songs. Mahler's music was heavily influenced by the folk music of his homeland, as well as by the works of other composers such as Beethoven and Wagner. His works often featured large orchestras and choirs, and he was one of the first composers to use recordings of nature in his compositions.
