for parents with infants, a knitting circle, a community dance workshop, a yoga class, and art students. She plans to continue these community-oriented concerts, encouraging people to combine live performances with their interests outside the concert hall and providing opportunities for parents to hear music with their infants, who might be barred from traditional concerts. In 2020, Hahn and AI roboticist and tech entrepreneur Carol E. Reiley cofounded DeepMusic.ai to work with artists and AI companies to amplify human creativity. Commissioning Hahn is a noted champion of new works. In 1999 she commissioned Edgar Meyer to write a concerto. She later recorded the piece with the St. Paul Chamber Orchestra. In 2010 a concerto written for Hahn by Jennifer Higdon and recorded with the Royal Liverpool Philharmonic was awarded the Pulitzer Prize in Music. She commissioned 26 contemporary composers to write short encore pieces for In 27 Pieces: the Hilary Hahn Encores. Among the composers are David Del Tredici, Jennifer Higdon, Du Yun, Elliott Sharp, David Lang, Nico Muhly, James Newton Howard, Valentyn Silvestrov, and Max Richter. For the 27th encore she held an open contest that drew more than 400 entries and was won by Jeff Myers. The international premiere tours, from 2011 to 2013, met with wide critical and audience acclaim. In November 2013 these 27 short pieces were released on Deutsche Grammophon. The recording won the Grammy Award for Best Chamber Music/Small Ensemble Performance. After playing Einojuhani Rautavaara's violin concerto, Hahn commissioned another concerto from Rautavaara, but due to his weak condition the project was thought to be forgotten. But after his death, it was revealed to conductor Mikko Franck, a friend of Rautavaara's, that Rautavaara had written two serenades for violin and orchestra. The serenades were premiered on Hahn's album Paris. In 2016 and 2017, in recital tours across the U.S., Europe, and Japan, she premiered six new partitas for solo violin by Antón García Abril, her first commissioning project for solo violin, as well as her first commission of a set of works from a single composer. She forged a relationship with García Abril during In 27 Pieces: the Hilary Hahn Encores. Digital and physical editions of the complete sheet music for these 27 encores have been released by Boosey & Hawkes. In 2019 Hahn and Lera Auerbach premiered Auerbach's sonata for violin and piano Fractured Dreams. Film music Hahn began her film recording career
