In finding appropriate registrations for this concert, I was impressed by how much was possible using only the combination pedals while hand-registering the Choir and couplers, making only occasional modifications to the pre-set combinations, and I was able to achieve results that, both in terms of dynamic relationships and of tonal variety, were superior to those that I had initially tried to achieve through registering entirely by hand. My curiosity about the concept of dynamic relationships in the organ led me to listen more carefully to the relationships among individual stops. I was surprised to find what I believe to be a concept of voicing that is grounded in four basic and distinct levels of dynamic intensity among the open pipes, albeit pipes of different scale. Essentially, all of the Diapason and string pipes of a given length sound at one of these four levels.
