So Gies himself designed the organ that he wished for in this room. His first drawings irritated Michael Becker, the organ builder and organ expert of the Hamburg diocese. It was something completely new. "Although the acoustics of an organ are completely independent of the form, and needs not any body of resonance, they are inconspicuous as structural objects," explains W. Gies. Usually organs are always built "cassette-like" against the wall. All those working together on the design and construction of the organ were stepping on new ground. For the painter and sculptor W. Gies it was the first and only organ that he ever designed. The organ builder Michael Becker stood before a new and unusual challenge: the construction oft an organ designed by n artist. The instrument that W. Gies and Michael Becker brought to reality required a bit of pioneer work.
