Composer
Jack Pepper (b.1999) is one of the UK's youngest commissioned composers, writing for orchestras professionally since his early teens.
His classical work exists alongside Musical Theatre and pop songwriting (music and lyrics).
Classical composer
In his teenage years, Jack composed orchestral pieces for the Royal Opera House, Classic FM's 25th Birthday, the Royal Philharmonic Society, for the Bournemouth Symphony Orchestra's 125th Birthday, for the Royal Liverpool Philharmonic Orchestra, The Band of HM Royal Marines and the London Philharmonic Orchestra.
Jack has recorded his work with acclaimed conductors including Sir Antonio Pappano, Vasily Petrenko and Kirill Karabits. His music has been broadcast on Classic FM and the BBC.
Songwriter
In 2025, Jack was invited to write the first-ever song expression of His Majesty King Charles III's vision for the planet. Called Harmony - after His Majesty's book of the same name - it was written to mark the 35th anniversary of The King's Foundation and premiered for The King at St James's Palace in June 2025.
Jack is also active in Musical Theatre:
UNLEASHED
A new stage musical co-written with BBC Radio 1's Matt Edmondson. It brings together magic, animals and mystery and takes us inside one of the most successful and notorious acts in Las Vegas history. It received its first public sharing at MAST Studios in November 2024.
DUET
Telling the true story of his piano teacher, this dance and song show is being developed in association with The Lowry, Mayflower Theatre / MAST Studios and Norwich Theatre. Songs from the show were premiered at the Royal Albert Hall in 2023 as part of the MFY Proms, and it has been featured on BBC Radios 2, 3 and 4 and on The One Show. It inspired Jack to create the Thank Your Music Teacher campaign.
GULLS & BUOYS
This children's seaside-themed revue tours primary schools each summer, supported by the Tasso Foundation, GLF Schools Foundation and RMG Associates. A mentor visits the school for weekly music sessions to teach a song a week, while the school collaborates across year groups to build the sets and costumes. Jack then visits for the dress rehearsal and final performance, accompanying them on the piano for their end-of-year production.
Jack has also written a number of individual songs (both music and lyrics) for standalone occasions, including:
- The Commonwealth (a project that saw a song co-written by Jack recorded by over 300 musical and youth groups around the world)
- The Holocaust Educational Trust (a song he performed alongside soprano Camilla Kerslake at the Roundhouse)
- The DMRC Benevolent Fund (Headley Court / Stanford Hall, a song he performed alongside The Band of HM Royal Marines)
