I plan on auditioning for conservatories next year (I'm in 11th grade right now) and there are some that ask for two movements from the Bach Cello Suites (I forget which conservatories in particular), and I was considering for that requirement to prepare the Prelude to Suite no. 1 and the Bourees from Suite no. 3, along with some of the other pieces and excerpts I'll be preparing. My question is simply: for auditions, should these movements be played in cello pitch or is that up to my own comfort? EDIT: I suppose the same question goes for the Vivaldi Cello Sonata in E minor, 1st and 2nd movement.
