Sheku Kanneh-Mason now attends the Royal Academy of Music in London but left a legacy at his old school, Trinity Catholic in Nottingham, before parting ways.
According to the Nottingham Post, the 18 year-old cellist donated £3,000 to the school after learning it was facing funding cuts.
The gift was money that he saved up from cello concerts and has enabled school to continue teaching cello for the next three years.
Kanneh-Mason told the paper he knew it was the right thing to do.
"I have had amazing opportunities at Trinity School, and to see other children not have the same opportunities as I had would be a huge shame," he said.
"Being a cellist myself the department of music is something that is close to my heart and I couldn't see it go, especially when I knew I could do something about it.
Trinity Catholic School said Kanneh-Mason "made a substantial contribution" to the future of the cello program" and it will be remembered as his legacy.
