How do you know when you become a pro musician?
Is it after you fully complete Alfred’s Basic Piano Library?
Is it when you surpass 10,000 practice hours and artists are beating down your door to hire you?
Is it when you can play sheet music like this with your eyes closed?
What is the official “Pro” threshold and how does one cross it?
Going pro is much more vague than that. It doesn’t depend on 10,000 hours of practice, though it may require that.
It doesn’t depend on a degree from Juilliard, though such an education would be helpful.
It’s not awarded to those who’ve taken lessons the longest.
