The "Trillende Lucht" Foundation annually awards a music prize to composers whose music makes a world of their own or of which such a world is evident. The foundation seeks to achieve its goal, among other things, by awarding a prize, the Open Ear, to a composer, regardless of age, career length, sex and / or nationality, as an appreciation for his entire work or at least one Substantial part thereof. The price consists of Ansuya Blom's artwork and a money amount. The prize winner is appointed by an independent jury every two years.
The wooden walnut box has been established in close cooperation with the artist and members of the foundation.
