Again, while use of the bellows on anglo/melodeon, English style is pretty much governed by the tune, there are occasions when little extra techniques/tricks can improve performance. There are also tricks to be learnt playing fast Irish reels in Irish style. For instance our Chris once cut a fold out of his bellows to make the reaction faster and it worked! (I don't recommend this on expensive boxes unless you're really going for it)

I would imagine that there are some techniques that are worth looking at when playing English/duet regarding bellows, and I would certainly be interested in looking at them.

My main box is a Wheatstone anglo special, quite big and heavy, and I still, at 67, can handle it standing up without neck straps but I don't know for how much longer I'll be able to continue doing this.
