there seems to be some difference of opinion between concertina makers and players as to what is the most important contributor to acoustics as regards concertinas.
is it the steel used for the reeds or the wood that is used in the construction.
what evidence is there that steel produces different sound from concertina to concertina?
there is evidence that choice of wood used in the construction affects sound.
there is also evidence that brass reeds sound different to steel, and that wooden ends sound different to metal ends.
how important is wheatstone radial construction compared to jeffries and crabb construction?
how important is the tapered reed chambers used on wheastone concertinas.
in my opinion the best concertinas I have heard have been Wheatstones, I am curious what is responsible for their sound.
