As a musician i have realized not more than just music notes are hidden within the pages of music.
Every first time wont be perfect but that doesnt mean stay muted.
Even if it seems everyone is at a faster speed.When your alone practice steady.
Like life,music will through notes you've never seen before.Stay determined and just be ready.
If you ever have to get through complex measures take them note by note.
Belive in yourself and i promise you'l never choke.
