He was probably also the Guionet who composed tensos and partimens with Cadenet, Raimbaut de Vaqueiras, Mainart Ros, Pomairol, and a certain Guillem.
Gui's career would have been little out of the ordinary for a 13th-century nobleman if not for his literary pursuits, for he was an accomplished troubadour in the Occitan language, leaving behind five or six lyric poems (or fragments), including a sirventes and several tensos.
[4] Besides his surviving work, his biographer records his composition of coblas (couplets) about love and "conversation" (de solatz, perhaps signifying humour or pleasure).
[4] His earliest tenso was with an otherwise unknown "Falco", which can be dated to 1200–07 on the basis of a charge of Falco's that Gui lived off the gifts of his patron, Count Alfonso: Senh'En Guy, del comte, / don enquer vos sove, / N'Anfos vostre senhor, / don ac man palafre / ses fre vostra seror ("Lord Sir Guy, you receive gifts from the count, Sir Alfonso your lord, your sister gifts of palfreys without end").
In 1220 while besieged in Castèlnòu d'Arri he addressed a poem to Bertran Folcon d'Avignon which survives in its entirety appended to his vida.
Gui vies for the identity of the "Esperdut" (a senhal) who composed three poems: a canso, a partimen with Pons de Monlaur, and a sirventes.
[7] It found support among T. B. Eméric-David, Paul Meyer, Ludwig Selbach, Stanislaw Stronski, C. Fabre, Adolf Kolsen, Carl Appel, D. J. Jones, Martín de Riquer, Dietmar Rieger, Andrea Brusoni, and P. T. Ricketts.
He argues that Cabrit must have been a member of the urban noblesse of Arles and owner of a small parcel of land near Tarascon, documented in a notarial act of August 1203 at the house of Bertran Porcelet and probably dead by 1225.
The author of the second part of the Canso puts an eloquent speech in Gui's mouth, in which he praises the Paratge (nobility) and denounces lo coms de Monfort que destrui los baros e la gleiza de Roma ("the count of Montfort who destroyed the barons and the Church of Rome").
