Flute Pieces- Difficulty Ranking

Hi,
I’m not looking to apply as a flute major in a conservatory but I’m sending in supplements to top universities.
I was wondering if any fellow flutists or musicians have an idea what type of repertoire is typically known to be challenging.
Is being able to play Ibert Concerto Mvt. 1 considered impressive, even among top musicians? What about Mozart in G?
What do flutists usually send in besides solo pieces from orchestral excerpts (i.e Mendelssohn’s, Debussy’s Afternoon of a Faun, etc.)? Thanks!

I asked my daughter, who has several flutist friends who are or will be applying to conservatories. She says they all complain about how hard the Ibert is. She says you should only use it if you play it really well, since it’s overkill for a non flute performance major.

I know nothing about the music supplement evaluation process, though.

@noviceatoller thank you so much! I’ll take that into consideration when applying. :slight_smile:
