Romanticism witnesses the flourishing of the social practice of public concerts: in 1828 the Société des concerts du Conservatoire introduced the habit of “going to a concert” on Sundays, day of rest, for all social classes. The concert programme includes symphonic pieces by Dubois with passages in which the harp stands out, an instrument that was revived with a new model in the early twentieth century, the so-called “chromatic” harp, which replaced the pedal mechanism with a string for each semitone; it was for this instrument that Debussy composed his Danses.
