As a student of Denis Gaultier, he enjoyed an excellent reputation as an instrumentalist, which is demonstrated in many contemporary sources where he was described as one of the greatest lutenists of his time.
From his works has survived a collection of twelve lute compositions in tablature besides a few individual works in manuscript or other compilations.
His works are written with a lot of harmonic freedom and nearly in an improvisatory style.
He trained as a lutenist with Denis Gaultier, of whom he was a pupil around 1630, and whose manner is reflected many times in his own artistic expression.
Like most of the great composers of his time, Dufaut showed a certain inclination for harmony, without departing from the discretion and refinement that characterized his art.
