I'm 17, finished 3rd year of musical high school and need a concert for my last year. I've been playing for 6+ years. My main pieces this year have been 3 movements of the Dragonetti nanny concert and Hertl's tarantella. Last year I did chanson triste. Do you think the koussevitzy concert is too advanced? If yes, what pieces do you recommend? I have a solo concert this year, and need some good programme.
