The grandest, simplest, and longest-lasting adventure I ve embarked on as a musician has been my quest to expand my repertoire. Ever since early childhood, opening the sheet music to a piece I love but haven t yet played has felt like a magical combination of winning the lottery and setting out on an epic trip. The clean, unused score is a freshly printed map. The texture of the page reminds my hands that I m holding a small, three-dimensional part of the composer s legacy. I m excited to think that each new work brings infinite expressive possibilities, and that it could stay in my repertoire for decades. Those hopes don t always pan out, but in the course of one significant early year in my life, they did twice. At the age of 10, I was given the violin parts to both Vieuxtemps s Concerto No. 4 and Mozart s Concerto No. 5. - Hilary Hahn
