Guilhem Ademar's career can be dated from a reference in a poetic satire of contemporary troubadours by the Monge de Montaudon around 1195.
The Monge playfully insults Guilhem as a "bad joglar" who always wears old clothes and whose lady has thirty lovers.
[2] One of Guilhem's more famous pieces is Non pot esser sofert ni atendut, a sensuous canso of courtly love wherein he is wishing that his lady's husband would go far away.
[3] In his primary love songs, Guilhem praises two ladies, one from Albi (Na Bona Nasques, a pet name) and another from Narbonne (Beatriz, perhaps her real name).
His love song Ben for'oimais sazos e locs is written as a message to his lover to be delivered by her porter, who is strictly warned to follow through.
In his only sirventes, Ieu ai ja vista manhta rey, Guilhem moralises in a slightly Marcabrunian fashion on how loyal and generous suitors are rejected in favour "fools and misers".
