Hello.

I posted this a couple days ago in the “Discussion forum”, that you might find relevant.
You can’t be more backwards than I was, so I know it’s possible.
I didn’t even think I’d enjoy it, but believe me, if you like music and your friends enjoy it, you’ll enjoy it, too.
Best, in my opinion, got somehow get a bit of practice in private, if you know anyone with a system at home, for instance.
Or find a song you like that you can sing along in your key, and practice it a bit. That way at least you’ll know you can sing it without worrying about where to drop/raise the key.
For me, it still took some “liquid confidence”, but that was just me.
Anyways, I’m new here too, but welcome.
