Classical music oftenly is associated as boring, muddy; as an activity for the older people. Eventually this older generation will be gone for good, leaving even less pubic than it now has. As this problem grows the relationship between classical music and the public shifts. The lack of connection becomes more obvious, making it more and more distant. Through the case study of the concert building De Doelen in Rotterdam, a design study with the concept of the "promenade architecturale" is held to explore the insights on how to revitalize this subculture by making connection with the public on many different levels. In order to also design an acoustic well-functioning concert hall, a research paper is written about the architectural interventions in optimizing the acoustic aspects of a concert hall.
