I'm in auditions time and I've realize this 2 tips, for myself, and people who feels the same or felt this at any time.
Play
Is a little bit stupid to say "Play" when You are talking about an instrument but some of us forget to be happy while we are playing because of the other's eyes. Play.. like in childhood. Because music is a new born and nothing else matters.
Is the most difficult thing to do... believe meDont listen to toxic people
Classical music is a big hole of mediocrity , egocentrism and envy. You have to acept this to be in peace with yourself. It should be more people who hates you than people who loves you and often, friends are not friends at all.
I have great friends , friends for years.. But a lot of people broke my heart too.
Music is expression. You're playing, you're are making this real.. You and your sound. No one sounds like you. DONT TRY TO BE LIKE THE OTHERS
