What should the music look like?
Expect music to have pencil and highlighter markings. Band class music should have notes and reminders on the music that are instructions from the band director. Private lesson music should have instructions from the private teacher. All music should have metronome tempos and corrections from the student as reminders for mistakes they have made; you might see notes circled or written cues to fix a problem. Once a mistake is made the first time, it should be lightly marked as a reminder so that it isn’t made again. You might also see key elements of the music highlighted such as key signatures and dynamics.
Something you shouldn’t see on music is every single note name or fingering written in. If your child is struggling to read their note names fast enough, they can use a note name app or website (such as www.musictheory.net) to build note reading skills.
The only music that should remain unmarked is “sight-reading” music; more on sight-reading music is written later.
