"Well, I now have a nearly new (and new to me) Anglo style C/G Hohner 20-button concertina. I have started off with Gary Coover's book Easy Anglo 1-2-3) and so far have learned to play a C scale. Well, almost. Any advice and encouragement appreciated.  \n\tI watched several YouTube videos on playing the Anglo concertina. Several admitted that the button/note laying can be a bit mystifying, but none were able to offer a rational explanation. Is there some hidden pattern that will make learning easier, or is it just a matter of rote muscle memory? History buffs? \n"
