Hi Bill,

I agree with you. Practical key signatures only go up to 7 sharps and 7 flats. As you have already pointed out, after seven essentials the key signatures go into the realm of theoretical and include double-sharps and -flats. Personally, I don't worry about all those extra theoretical key signatures that are listed because all the ones that I need are included and that suits me. The rest are superfluous and I can easily ignore them. In a few posts over time, Dr Peter Gannon has indicated that notation is an area that needs addressing and I imagine that your points are already noted.

To me, BIAB is about playing music in a very practical sense and, for my purposes, it does that wonderfully well.

All the best,
Noel
