He was a respondent to Jehan Bretel in two jeux partis judged by the trouvères Perrin d'Angicourt and Jehan le Cuvelier d'Arras and the banker Audefroi Louchart.
Besides his two jeux, Gaidifer wrote seven chanson courtoises, six of which appear only in the Rome Chansonnier.
His style is described as "sharply circumscribed": all his poems are isometric and octo- or decasyllabic.
All his simple melodies are in bar form, but spanning wide ranges (often an octave or higher).
In Tant ai d'amours, which served as a model for Lambert Ferri (J'ai tant d'amours apris et entendu) and Adam de la Bassée (Ave rosa rubens et tenera), there is repetition in the cauda.
