Music

Music in medieval cycle plays was very important. There would be music from hired minstrels, chorus' of angels, and other ways, both vocal or instrumental. Music would be played before the plays would start, during transitions between the scenes, and even entertain the crown once the play was finished. The people creating the music would range from, as mentioned before, a chorus of angels (most likely choir boys), to minstrels, to the individual actors singing either popular tunes or religious hymns. Here I found a video that someone took of some current day musicians hired to play at the York Mystery Play Cycle.
According to Brockett on page 93, some of the plays, or their stage directions, hint at there being dancing, and that it played a large role, but there isn't much known about this.
