Hahn’s distinct stylistic choices honor the traditional violin literature while delving into the unexpected. In recent seasons, in recital tours across the United States, Europe, and Japan, she premiered six new partitas for solo violin by composer Antón García Abril
. The works were Hahn's first commissioning project for solo violin and her first commission of a set of works from a single composer. García Abril was also one of the composers for In 27 Pieces: the Hilary Hahn Encores
, Hahn's multi-year commissioning project to revitalize the duo encore genre.
Hahn is an avid writer, having posted journal entries for two decades on her website, hilaryhahn.com, and published articles in mainstream media. Her violin case comments on life as a traveling companion, on Twitter and Instagram at @violincase.
