Me before: " and they all said "Pretty boxes but impossible to hold properly"

And Dick: "rather like asking someone who is not a plasterer, how to use plastering tools and the technique of using the trowel to put plaster on the walls,not very bright really, Guran " and "why not ask a trombone player how to hold a violin".

Hello Dick, always inspiring to "see" you! There is a lot of sense in that of course...the craftsman is expected to know his craft better than the layman.. but one problem still is that the plasterer mostly doesn't know how to avoid having to retire from the job prematurely because of arthrosis in the shoulder or the neck...neither does the fiddler know that in several studies 75% of fiddlers report having severe complaints from extremely unhealthy working habits. Yehudi Menuhin, one of the foremost violin players, has said that doing his daily yoga routine has been of greater importance for the fiddling success than practising the violin...It was hardly a violin pro who told him that either.

Anyway Dick, the spontaneous remark from non concertina players that the concertinas have terribly primitive "handles" ought to be taken seriously and from your own viewpoint maybe not least since the mid 19th century inventors of "our" common instruments - the "anglo" "duet" and "english" - were not musicians themselves but technicians and the present knowledge in the field of ergonomics to more than 90% has manifested itself after 1950.You can not blame these old inventors for being ignorant but we definitely don't need to be ignorant ourselves when knowledge can be found behind the corner...
