Franz Joseph Haydn was an Austrian composer of the Classical period. He was pivotal in the evolution of chamber music forms like the string quartet and piano trio. His contributions to musical form have led him to be called "Father of the Symphony", "Father of the String quartet" and "Father of Sonata form".

Arvo Pärt is an Estonian composer. Since the late 1970s, Pärt has worked in a minimalist style that employs tintinnabuli, a compositional technique he invented. Pärt's music is in part inspired by Gregorian chant. His most performed works include Fratres (1977), Spiegel im Spiegel (1978), and Für Alina (1976). From 2011 to 2018, and again in 2022 and 2025, Pärt was the most performed living composer in the world. The Arvo Pärt Centre, in Laulasmaa, was opened to the public in 2018.
