I've been interested in writing tabs for a while now, as I feel it would help train my musical ear as well as possibly helping other people who aren't that great at learning by ear and want to learn songs by relatively obscure bands. I've made a few tabs and I like to think I'm alright at it, but I can never figure out how to determine what the BPM is, what time signature is being played in currently or what tuning the band is playing in. Assuming there are no other tabs for the band so I can't check what tuning the band is playing in I have no idea how to find out, and I'd think it's nearly impossible. So I was wondering if there's some way I can get some help on those issues, as I can't find anything on the internet. Thanks in advance, I guess.
