Aspen Barker started her journey with music when she was in 4th grade, at an after school strings music program in Miami. Inspired by her opportunity to play alongside the New World Symphony and Amernet String Quartet, Aspen decided to continue to pursue her music career in New Orleans. 

She went on to receive her Bachelor of Music in Violin Performance at Loyola University in New Orleans and Master of Music in Violin Performance at Longy School of Music of Bard College. She has studied with Amy Thiaville, Nadja Salerno-Sonnenburg, Paula Majerfeld and Karla Donehew Perez. 

Because of her beginnings in community music programs, Aspen has dedicated her time to volunteering at similar organizations that aim to bring music to all, such as Miami Music Project, Make Music Nola, Boston Strings Academy and El Sistema. Now a permanent Boston resident, Aspen works full-time as a music teacher, bringing her dedication to accessible music throughout the city. Aspen has performed with multiple ensembles, like the Reading Symphony Orchestra, Ensemble Uncaged, Palaver Strings, and Mass Opera. She is a permanent member of the Du Bois Orchestra. She has worked with many artists in her career including Michael Tilson Thomas, Joel Smirnoff, David Effron, Andy Kozar as well as members from Aizuri Quartet, INTERWOVEN, Horszowski Trio, Trio Gaia and A Far Cry. 

In Fall of 2022, Aspen co-founded GAIA Quartet, a string quartet that serves to inspire young female musicians and innovate the music industry. GAIA Quartet was awarded Graduate Fellowship Quartet in Residence at Longy School of Music of Bard College, working closely with department chairs Alexandra Du Bois and Ralph Farris.
