But with regards to traditional Irish music, there is so little technique needed that it is common for amateurs to be exceptionally good.
neilidh boyle, a man with a lot of technique, referred to it as jungle music.
irish music requires good technique., the same as any other music, Brendan Power has good technique, Joe Burke has good technique,I could list hundreds of players with good technique, you are talking nonsense, if you have bad technique you are limited in what you can achieve.you cannot play any instrument well without practising and acheiving good technique.
and I am not referring to being able to move out of first position on the fiddle, some fiddlers can only play in first position, but the rest of their technique is good.
