I was taught H instead of B 30 years ago, and it makes me mad - my brain still refuses to think of notes as simply a rotating portion of ordered alphabet letters. I spent last two years trying to get back into piano and guitar and I feel I'm constantly hampered by not having that intuitive "oh, c to g is 5 notes" or even "what comes after B is C" and "what comes after G is C". I literally have to count on fingers as if they're randomized symbols (and fwiw I am pretty good at intuitively grokking mod 7 in other contexts) It's awful.
