In 1999 Hahn said that she played Bach more than any other composer and had played solo Bach pieces every day since she was eight.

Bach is, for me, the touchstone that keeps my playing honest. Keeping the intonation pure in double stops, bringing out the various voices where the phrasing requires it, crossing the strings so that there are not inadvertent accents, presenting the structure in such a way that it's clear to the listener without being pedantic – one can't fake things in Bach, and if one gets all of them to work, the music sings in the most wonderful way.
