How Do Concertina Reeds Go Out Of Tune?

I could be wrong, but an instrument I was working on seemed to go slightly out of tune when I adjusted the action to make the button heights consistent, thus altering the heights the pads lifted to.

This is a good point you  make, Alex.

I tend to do servicing in this this order: renew pads (and any springs), renew valves, adjust action set, tune reeds

However the most common cause over time, is the phenomena of work hardening ... this makes the reed 'spring' stronger and more difficult to move under the influence air flow. A situation which can flatten the reed pitch.

 

I would have thought that work hardening would make the reed stiffer and hence raise the pitch rather than flatten it.

 

When I received my new Holden a few months ago the whole instrument seemed to drift sharp as I played it in. A mechanical engineering friend of mine suggested work hardening as the most likely cause. It was re-tuned within a couple of months and has been pretty well stable since then.
