The chief poets whose influence can be detected are the troubadour Rigaut de Berbezilh and of the Sicilians Giacomo da Lentini, Guido delle Colonne, and Stefano Protonotaro.
Kenneth McKenzie describes Chiaro's "style" as developing over time and containing widely divergent elements under opposing influences: .
at one period of his activity Chiaro decked his verse in plumes borrowed from the Provençal and Sicilian poets and from Guittone d'Arezzo; but there is great variety in his work; we find political poems, realistic poems in popular style, attempts at philosophy, and finally indications of the influence of Guinizelli and the dolce stil novo.
When deviating from the trobar leu into more difficult and complex construction he is usually conversing with guittoniani, such as Pallamidesse Bellindoti or Rinuccino, with Monte Andrea, his most common correspondent, or with Finfo del Buono.
In 1267 Chario composed Ahi dolze e gaia terra fiorentina to reprimand his fellow Florentines on the occasion of their surrendering of power to Charles I of Sicily, whom they made podestà while the Ghibellines were sent into exile.
