1911 Encyclopædia Britannica/Choragus

CHORAGUS (the Lat. form of Gr. χοραγός or χορηγός, leader of the chorus), the citizen chosen to undertake the expense of furnishing and instructing the chorus at the Dionysiac festivals at Athens (see Liturgy and Finance). The name is given to an assistant to the professor of music at the university of Oxford, whose office was founded, with that of the professor, in 1626 by Dr William Heather.
