The Institute of Mediaeval Music
Scarcely anywhere else in the repertory of lyric poetry is the identity of the poet and the composer quite as apparent as in the works of Guillaume de Machaut, the foremost French poet and musician of the fourteenth century (d1377). His works with music should be approached confidently as integral lyrics, as composite works of poetry and music, because he wrote about the process of providing music for poetry and writing texts to be set to music. Furthermore, he specified the sequence of his own compositions- narrative and lyrical, poetical and musical - all in a single book.
