These sessions present new research by musicologists of the Cantus Planus research group of the International Musicological Society (IMS). The topics vary but are all concerned with monophony in medieval liturgy. Session III takes up the general theme of the IMC: the natural world.
I plan to write about Haymo of Faversham’s reform of the pontifical service books for Franciscan use in the 1240s, and specifically the connections between them and related works that reflect on their reception and promulgation among the friars. This past summer, while examining manuscripts from the Vatican Library, the British Library, and various archives in Germany, I discovered that some of Haymo’s ordinals are compiled with constitutions about liturgical music, composed by Pope Innocent III, that describe its rhetorical and affective character. Others are compiled with theological texts by the Franciscan David of Augsburg, who offers instructions about the performance of liturgical music that would seem to elaborate on Innocent III’s views. I have yet to see whether these reforms bear any influence on the musical reforms we find in the Franciscan service books. That is part of this year’s work. I’m sorry if this seems vague. It is quite a fresh piece of research for me. I have treated David of Augsburg in a different way, to deal with some rhetorical aspects of Franciscan music in theology, vernacular song, and preaching. In a sense, I would, in a presentation at Leeds, be connecting that puzzle to Haymo’s reforms and Innocent III’s constitutions.
This paper will deal with the concept of staging through the information provided by rubrics in liturgical manuscripts. The paper will involve discussions of texts and music from the 10th through the 15th centuries.
