In his three motets with tenors taken from secular songs, Guillaume de Machaut experiments with upper voice structures that borrow from the talea principle used in chant-based motets, creating hybrid forms that reflect aspects of the motet's overall subject. In two cases, Machaut sets up upper-voice taleae that do not coincide with their song-based tenor but interact with it in interesting ways. Trop plus est bele / Biauté paree de valour / Je ne sui mie certeins (M20) balances these formal principles to reflect a perfect love balanced between the dedicatory and the sacralised, while Lasse! comment oublieray / Se j'aim mon loyal ami / Pour quoy me bat mes maris? (M16) creates three opposing forms that reflect a Lady looking in two different directions, towards a beloved and a husband who abuses her. Dame je sui cilz qui weil endurer / Fins cuers doulz, on me deffent / T. Fins cuers doulz (M11) does not define regular upper-voice taleae, but rather uses the tools by which taleae are defined in the upper voices – long rests, hocket sections, and melodic repetition – to merge disparate formal principles in the service of a motet that discusses a woman who merges a soft appearance with a hard reality. Here Machaut also uses hexachordal punning, combining sharps and flats to express the Lady's contradictory qualities.
