I no longer believe centrifugal force accentuates bending as I noted in my post on bending, specifically this statement:
“Centrifugal force? I believe it contributes, but I have no evidence. Yet my instincts and what I hear keep me believing that it helps accentuate bends on the lowest notes with the largest, heaviest reeds.”
By looking at my melodica design, applying some critical thinking, and visualizing how I accelerate the melodica away from a stationary mic to get some Doppler effect, I see that the centrifugal or acceleration forces would actually work on the reeds in the wrong direction, working against the bending effort.
