Erik Satie (1866–1925) was a French composer and pianist known for his eccentric and innovative approach to music. A key figure in early 20th-century music, Satie's work broke away from Romanticism and traditional classical forms. His compositions, including Gymnopédies (1888) and Gnossiennes (1890), are characterized by simple, repetitive melodies and unconventional harmonies, creating a dreamlike, meditative atmosphere. Satie was also known for his quirky personality and unconventional ideas, influencing avant-garde movements like Surrealism and Dadaism. His use of humour, minimalism, and non-traditional notation marked him as a precursor to later experimental music.
