Joseph-Hector Fiocco was a Brussels-born Baroque composer and violinist active in the early 18th century, working in the musical milieu of the Southern Netherlands and producing both sacred and secular repertoire. His music blends Italianate melodic influence with French and Flemish stylistic traits across choral, keyboard and chamber works, and he held church and court music posts where his output reflects the shift from high Baroque complexity toward clearer, more galant textures.
