For me the major advantage of the anglo over other systems is that you have a home position with eight fingers on eight buttons. Depending on what tune you are playing and your personal inclinations and skill you move your fingers away from that home position to a greater or lesser extent, but in that home position you already have sixteen notes immediately available.

Of course, like most things in life, the anglo also has disadvantages. For some people the completely different sets of notes on push and pull are mind bending. And you can't (as on the other systems) change bellows direction independently of what notes you wish to play.

I advise anyone wondering what kind of musical instrument to take up to beg or borrow (preferably not steal) several different kinds to have a go on. With luck, one kind will quickly feel more natural than the others.

I dabbled with various instruments in my childhood and early adulthood, then one day I came upon a 20-key German concertina in a store room. I fiddled with it for a bit and found that it made some sense to me. I found the owner who sold it to me for the same £2 that it had cost him. I soon graduated to better instruments, and eventually to several 40-key anglos.
