Between October 1458 and 31 March 1459 the brothers were assigned to the care of Jehan Gaudier, and in 1462 the composer Guillaume Faugues became briefly magister puerorum (master of the choirboys); he may have been a formative influence on the young Philippe.
Ockeghem also visited Bourges that year, but if the boy made his acquaintance then is not known; however the influence, and possibly friendship, of the older composer was to become clear later.
He used sequential repetition, and was perhaps the first composer to write a piece in which imitation was the main structural device from beginning to end (the Regina celi).
He also was capable of creating long movements by juxtaposing sections of varying texture, but without disunity; his Messa de Franza is the most famous example.
Eloy d'Amerval mentioned Basiron in 1508 as among the "20 great composers of the 15th century"; both Pierre Moulu and theorist Gaffurius praised him highly; and most famously, poet Guillaume Crétin, in his Déploration sur le trépas de Jean Ockeghem, listed Basiron among the sweetly singing angels in heaven welcoming Ockeghem to join them.
