Abstract: A hybrid work, G. Martin’s Confiteor reveals not only a professional path but also a spiritual quest. Throughout the journey undertaken by this musician through the heart of the kingdom, his personal voyage was ever present. As cantor, organist, or tutor, he also filled many roles in his everyday professional life. In complement to Annibal Gantez’s work, Martin provides us with an atypical record, one with mysteries still left to unveil.
