Using thumbs to play Hayden Duet Concertina in General Concertina Discussion Posted December 4, 2019 51 minutes ago, Łukasz Martynowicz said: IMHO thumbs are too cruicial for fine outwards bellows controll and articulation to be „wasted” on just one or two easier to play notes. Besides, thumb joints axis orientation makes thumb movements a lot slower than other fingers’, especially when trying to reach further lower buttons. And frankly speaking even six notes at a time sounds rich enough on a concertina, with eight fingers being enough for smooth chord transitions in nearly all cases. I can imagine two or three thumb operated drone base buttons on the left side outside of Hayden layout being musically usefull, but otherwise it is wasted bellows controll for me. Thanks -- Had the same thought yesterday while playing re: how many notes are really needed (or desirable) at a time. Part of the issue is that I bought a Stagi, which is bigger than other concertinas, but 4 (long) fingers do seem to be enough even on the Stagi.
