The Villa Sponte is a place for all sorts of cultural activities, and its known for its good acoustic.



The Resonanzio project would not exist without the valuable feedback we have received from fellow musicians and other discerning music lovers. Their input, suggestions, and constructive criticism helped us to develop and refine the resonance plates and sound podiums. We are especially grateful to the musicians, who kindly did the testing at the Sendesaal Bremen: Yuko Hara (Viola), Louise Pühn (Harp), Imke David (Gamba),  Simon Hartmann (Doublebass) and Johannes Rake (Cembalo).
