In 1535 Sylvestro Ganassi published in Venice the first treatise developing the technique of the art of ornamentation at an unprecedented level of rhythmic complexity and virtuosity. Playing the recorder, the instrument to which Ganassi devoted his work, Denis Raisin Dadre applies the rules of the treatise to the repertoire that Ganassi practiced, frottole and, above all, the madrigals of Philippe Verdelot. With the ornaments, the music proves to be a living art that practices a constant rhythmic shift, the exuberant virtuosity of improvisations and a ‘swing’ that would be typical of jazz in the 20th century.
