"Already at the age of 21 I played the complete organ works of Bach - and this by memory. As a child and youngster I had been taught by one of the last master-students of the legendary Helmut Walcha, and I completely had been affected by this style of insight into Bach and the internal structures. This method of regarding the independent coherence of all the voices gave me a special comprehension of Bach and his philosophy. Lastly one can say that I have been growing up with Bach, even to this day. If you understand the free organ works (preludes, toccatas, fugues), the chorales, and especially the trio sonatas, you have an insight into Bach that others don’t have. Especially the soloistic and independent leadings of the three voices of the trio sonatas is artistically the major aim of an organist; and already the Orgelbüchlein, the part 5 of the Peters Edition, shows Bach in all his structural and emotional effects. Albert Schweitzer described the Orgelbüchlein as something where the tonal speech of Bach is unbeatable. The comprehension of the organ-Bach is an understanding of the counterpoint and the polyphonic structures, and the coherence of Bach himself."
