Three sequences produced by interactive installation that transposes real-time ofthe architecture of a remarquable building, the Gothic cathedral of Mende, in France, into sound and musical sequences. The visitor entering the cathedral is provided with a headset and a small module, the "harmonic lantern". When he walks, the transposition is recomputed for each of his positions, generating a harmonic trajectory of which he is simultaneously the composer, the musician and the audience. The sound clip includes trajectories by three different visitors.
