GAMPSISS was an interdisciplinary project that researched whether it would be possible to train the listening skills of a concert audience by making use of serious games and gamification that are especially designed for that purpose. Listening being an essential social skill, a concert hall can be interpreted as a massive training environment to become a better listener, and eventually: a better citizen. Combining academic, science and artistic research we researched listening to music and listening to other people. We then researched which game would serve this goal best, and built a smartphone game and created a gamificated orchestra performance.
