Thank you for your continued dedication and curiosity with music.
Take a look through all your notes this holiday and figure out what exercises you like the best. Try to do one for slurring, tonguing, fingers, as well as playing some music every day.
Some more specific homework to check out will be: every major arpeggio (and review the scales too), first five notes of a major scale for range building, and All Through the Night for musicality. Feel free to read through some of the other music I’ve sent you in the past. Remember you can also learn ANYTHING by ear! :)
