Foolestroupes 'secret' is fascinating - and bloody obvious if you think about it. I just never thought about it that way before - despite having studied Benade's terrific books on the subject. I shall certainly take this into account in future - even if this means deliberately searching for the effect :)
Thanks for that one.
On wandering bows - I try to move the bow a little as possible in ANY direction - keep it at 90 degrees and move it just enough to get the best note - I guess this qualifies as an 'interesting' idea.
Oh - and on carpal tunnel syndrome - I got that in my right arm from using a thumb strap on a one row melodeon. The bonus was I gave up the box to concentrate on fiddling. Never had any left wrist problems despite resting fiddle on my arm for about 25 years - guess it's to do with the way you're built. But then I don't attempt complicated stuff - I just try and play the simple stuff as well as I can.
