What is your minimal level that begginer guitar player has to cross to call themselves guitarist?
Have picked up a guitar, played a note and smiled.
I can’t remember who wrote it, but there’s a short essay by a Japanese noise rock artist (maybe Agata from Melt Banana?) on ‘How to be a guitarist’ and it basically says ‘Get a guitar. Tune it if you like but this isn’t necessary.’ So, yeah: that’s about where I’m at on the question.
If you ever try, or even have tried, good enough.
Don’t worry about labels - stick with the hobby, it’s good for ya.
Don’t really think there’s a minimum - sure maybe you ought to have picked up a guitar but there’s no minimum proficiency for creative arts.
