13. @1lowhit it's when the notes are invisible, its really hard
14. so u have to strum when entering a cheat?

16. @1lowhit It's when you play the song without the fretboard, so you have to know every single note if you played a song alot. this means that when the song starts, the fretboard will not show up.
