When you're overwhelmed, sometimes things stay in your subconscious for a while before resurfacing.
This happened to me at the recent Noel Hill concertina school in Cincinnati, and what just bubbled up from my unconscious turns out to be something I"ll probably value the rest of my concertina playing life.
This is what is bubbling up now. At some point, Noel corrected the way I was holding the instrument...on my right thigh. He suggested I change it to my left thigh, because the air-button hand -- the right hand -- is the "bowing hand" of the instrument. He made several comparisons between the fiddle and the concertina during the school, this was one that I'm really glad is coming back to me.
Keeping this in mind is helping my bellows and air button work a lot, simply by giving it a frame or concept to hook it to. A simple and powerful concept.
