Being able to play alone but not with others
Hello, I was at a session today and it was great fun, but when it was time to play I just instantly forgot the notes to the tunes and could not keep up. I can’t put my finger on why (pun intended) because when I’m playing alone (yesterday in fact) I can play them without missing notes and keeping a pretty consistent rhythm. It’s puzzling me. Is this something a lot of beginners go through? I’m just curious and a little worried.
Any and all responses are appreciated!!
