He knew either Gace Brulé or the Chastelain de Couci, two of the first-generation trouvères.
Most unusual are the presence of a melodic tritone in two sources for Fine amours et bone esperance and of a sharpened subdominant in Chanter me fet ce don't je crien morir, both created by the use of accidentals.
Fine amours served as the model for an anonymous composition of the same name (the second line beginning Me fait), an anonymous piece beginning L'autrier par une matinee, and an anonymous song to the Virgin Mary, Douce dame, vierge Marie.
The music of Chanter me fet was used in two different readings of Pour la pucele en chantant me deport by Gautier de Coincy and the lyrics were a model for the anonymous Destroiz d'amours et pensis sans deport.
The other pieces attributed to Pierre are Quant foillissent li boscage and Tant sai d'amours con cil qui plus l'emprent.
