Blue Heron is a professional vocal ensemble that combines a commitment to vivid live performance with the study of original source materials and historical performance practice. Blue Heron’s principal repertoire interests are fifteenth-century English and Franco-Flemish polyphony, ranging from Dunstable and Du Fay through Ockeghem to Josquin; Spanish music between about 1500 and 1575; and neglected early sixteenth-century English music, especially the rich and unexplored repertory of the Peterhouse partbooks (c. 1540).

Most concerts take place at the First Church in Cambridge, Congregational.
