I would like to know more about this energy from 
the artist's fingers. Does it change frequency from note to note?
Does a poor performance leave a dissonant 
imprint on the soundboard?
Is this why I can't get the unisons on Prof. J---'s 
piano to stay in tune?

                           Mark, thanks for coming 
                          across this clip.  Knupfer's claim is valid, 
                          artist's 
                          do leave tonal imprints on the 
                          soundboard from a strong performance. 
When
                          checking after a concerts I 
                          have heard is assertion. Bill Garlick taught 
                          the 
                          same theory about Steinway 
                          keybed design and the resonating cavity 
                          created
                          by floating the middle spruce 
                          slats of the bed. Energy transferred through 
                          the
                          artist's fingers reaches 
                          through the keyframe to keybed setting the 
                          unglued
                          slats in vibration. This is 
                          the basis of his thinking. Checking the studs 
                          with
                          the 
                          sustain pedal down is critical for this connection to 
                          work.  The
                          guy had 
                          his hands full with the pianist, better not mention 
                          names, 
                          declaring the 
                          "perfect" instrument isn't perfect enough for all 
                           pieces.

                            They 
                            must have used awfully small cameras for this, and 
                            either several of them or else multiple takes. I'm 
                            really looking forward to seeing this. Anybody heard 
                            of Mr. Knüpfer? This film could be a great promo for 
                            our services. Click the little "watch" button on the 
                            lower right of the photo to see the clip. The recording 
                            of Bach's Art of the Fugue is already available, and 
                            I'll be curious to see how the piano comes 
                            across.
