In this paper Georgius Macropedius, rector of the Hieronymus Latin School in Utrecht (c. 1530 1557), is examined as the presumed composer of the music in his plays, both comedies as well as serious religious plays. Choral music played an important role in the separation of the play into five acts and provided an opportunity for moral reflection on the subject matter presented. Macropedius kept the music extremely simple. The frequent reuse of melodies suggests that he often lacked either the time or the inspiration to compose afresh. In his annual school songs, however, Macropedius seems to have given his compositional skills a bit more of a workout.
