It works
Yes, the keyboard works. If I had not forced myself away from it, I would still be there now, picking tunes. It is absolutely wonderful. The only danger is that - even though it seems to me rather small compared with some I have seen - it has so many tricks and features that it is perfectly possible to go on for minutes playing something very much like music without actually paying any attention to the keys. What I want to do is learn - or rather, re-learn - to read music and play it at sight. But what a wonderful thing it is, to have a serious musical instrument at last.
