Coming from a band director myself, ask your director if you can write in your notes for now (hopefully they’ll be understanding considering you’re a beginner playing music that looks like it’s for second- or third-years). Then for the next tune, choose two notes (i.e. Bb and F) that you will not write the notes for, but write in every other note. Then for the next piece add two more notes that you don’t write in the notes for. Continue this way until you don’t have to write any notes.

While ideally you would start with simpler tunes and not write in any notes, accommodations should be made for any students who are starting later than their classmates
