DLW

Very often I am asked how I can endow grand pianos with so much sound even in acoustically unfavorable rooms. The answer is simple: sound is not magic, but physical reality - and hard, patient work. And the most important thing: listening!

The fact that Christopher Dell, Christian Lillinger and Jonas Westergaard, of all people, are three non-pianists on the trail of my "sound secret" is not surprising. Because anyone who has experienced one of their spectacular concerts live knows: listening, analyzing and reacting are part of their uniqueness.

Here is the amazingly precise DLW analysis of my sonic work with the "615313" at the DLW Festival in Cologne:

"The sound of "615313" is composed through a network of structural work: Stefan Knüpfer's work of dealing with overtone spectra, formants in spaces and with the spaces themselves is very much in line with our diagrammatic work. The way he sets the overtone spectra of the strings in motion in an outstanding way (and nobody knows it) in delicate and patient work shows: space is vibration."
