Jocelyn Chambers has always been a creative entrepreneur, learning how to play piano at age 7 and running Sweets by Jocelyn at age 9. Music and film deeply resonated with her as a young child and once she discovered film scoring as a career option, it was a no-brainer that she would pursue it. She began studying composition at the Armstrong Community Music School, winning the Texas Young Composer’s competition twice in 2011 and 2013. She attended the American Festival of the Arts, where she wrote the string quartet "Enigma for the Night" in collaboration with the Houston Ballet. Chambers went on to study at The University of Texas at Austin, where she received a Bachelor of Music Composition and was honored by the College of Fine Arts for her advocacy and activism.

She moved to California, pursuing a graduate certificate in Film Scoring from the University of California at Los Angeles. While studying, she began working as a post-production assistant on Netflix’s “Grand Army” and “Designated Survivor”, eventually scoring spec music for both projects. She also scored “Mama Gloria”, a feature documentary highlighting the life of Black trans elder Gloria Allen, and “In Favor of Fetus,” a short documentary detailing women's experiences affected by Wisconsin’s Cocaine Mom law. During the height of the COVID-19 pandemic, she revived Sweets by Jocelyn, which she had previously put on hold to focus on composing.
