Isabella Gellis is a British-Canadian composer of acoustic music. She has a fondness for storytelling, and her music often focuses on the sincerity of the absurd and surreal. Training first as a pianist and violinist, she started composing in 2014, a year which saw her concert debut as a composer: a piece for eight hands on one piano at Wigmore Hall, written for the Junior Jaques Samuel Intercollegiate Piano Competition.

Between 2015 and 2022, she studied at the Academy with Edmund Finnis, Christopher Austin and Morgan Hayes, graduating with a Bicentenary Prize for all-round excellence and the Musicians’ Company Priaulx Rainier Prize.
