Graphic campaign for L’Auditori de Barcelona ( Barcelona City Council) to advertise a new fun family activity at the Museu de la Música: “Dirigeix l’orquestra, dirigeix la banda” (Conduct the orchestra, conduct the band). The installation gives visitors a taste of what it feels like to be a real orchestra conductor. By moving their arms, the visitor can change the tempo and the speed of a performance. Our graphic system is derived from the format of sheet music which encloses the name of the event. Notes are represented as circles that move through the score expanding and contracting to convey the fluidity of the music.
