In the last few years I have been concentrating on the development of the SoundStone. Daily efforts, experiences with the SoundStone, testing, reflection on, and observation of the SoundStone have led to a wealth of knowledge over a long time period. All my energies have been challenged.

In concerts with Friedemann Dähn and Manfred Kniel, I developed my abilities and knowledge even more. Here I experienced the resonances and responses of the musicians, the rooms and the audience, many of whom did not want to leave, but came forward to talk and see. The increasing conversations, which occurred after the concerts, often became correspondence expressing the wish to have me teach my art to others. Having finally decided, I began to instruct individuals in the art of playing the SoundStone, as well as developing courses and workshops. In the summer of 2004, we had the opportunity to work several hours daily for one week with 30 participants at the Evangelischen Akademie Tutzing at Starnberger Lake. It was a crucial experience and the basis for workshops which we now offer on a regular basis.
