[Harp-L] Gaskets?

I think the real issue isn't always air leakage, it's resonance leakage, or something along those lines. Impedance maybe? Some keys are affected worse than others by warped plates. Which makes me think there can be noise canceling coming into play on those keys. It can have a huge effect on bending that chro players might not "get". It can also definitely make it hard to tune octaves involving the upper register. On my wood '64 there's a screw hole on the mouthpiece side of the plates, screw long since gone. The reed in that chamber will barely make a sound unless the hole is plugged. Seems there's ample supply of air, that hole is small. I epoxied it shut and it plays great, so the problem wasn't due to lack of clamping force. The other reed in chamber is valved, so no leakage there. There's more going on than people think, I think.

In the vast majority of cases, leakage under the reedplate is minuscule compared to leakage through the opening reeds in a diatonic or through the slide in a chromatic. Although gasketing may reduce leakage by a tiny amount, the % reduction of total leakage is imperceptible.

This isn’t a character flaw but human nature.  My car runs better when the windshield is clean.  I like Coors beer because it is made with rocky mountain spring water.  I use Ivory soap because it is 99.44% pure.  Etc…………  The thing operated on hasn’t changed, but my subjective perception of it has.
