My point was that sharp keys and flat keys are the same keys with different names.

Doesn't matter whether you call it Bflat or Asharp I still won't choose it to play in. Or rather I'd use a capo.

But nothing wrong with playing in F. It's a lovely key to play a guitar in, with my favourite relative minor.

"The black notes 'feel' nicer on a piano as they are all smooth and a little like kitkats (which are a chocolate snack ...in case they are native to Britain!)" No need to explain. KitKats were invented in England. Glad to hear they apparently caught on in America.
