During the opening of the new Sundancer building in Oosteind I improvised a 432 Hz concert. I found it very special to experience what the music did to people, it was wonderful to hear that people were touched and moved afterwards. For example: "I haven't been able to express my emotions properly for years, and from the first tone I felt free and tears come up." How special is that! Thank you audience, Piet and Rieneke from Sundancer for the nice atmosphere.
