DD is in year 6 and has recently started flute lessons at school. She'd like to join the orchestra in year 7 (through school) for which she needs to have done the ABRSM grade 2 exam. She got a distinction for piano grade 3 last year and is relatively familiar with music theory (working toward grade 3).
Long story short, being able to read music and understand music theory, what would be the expected progression timeline for a flute grade 1 or 2? Is there a big jump between 1 and 2? She practices the Abracadabra pieces happily for 10-15 minutes a day.
