JAM Duo comprises Jules on Piano and Anne-Marie playing the Cello. The sound of piano and cello is one of the most sublime combinations in music. We perform for weddings and events all over the UK and Worldwide. Our repertoire is an eclectic mix of classical and contemporary music to suit all tastes and audiences.

Based in the Cotswolds on the Gloucestershire / Wiltshire border, JAM Duo are Award Winning Wedding Musicians. They have an ever expanding repertoire with a collection of music ranging from 16th classical through to modern day pop and rock. Regardless of whether you’re looking for some classical music, contemporary, or the most popular combination, a bit of both, JAM Duo have some stunning arrangements which will sound perfect at your wedding or event.


The name JAM Duo is quite simply based on our names. Jules & Anne-Marie – JAM.

Jules and Anne-Marie met whilst running a choir together in 2019. This resulted in the formation of JAM Duo in March 2020 with a desire to promote live music for weddings and events. Jules and AM are both classically trained musicians and love to perform together. From time to time they also perform solo gigs, Jules as pianist and Anne-Marie Humphries as Cellist.

Anne Marie Humphries
Anne-Marie Humphries, JAM Duo Cellist – August 2021

Anne-Marie Humphries is an accomplished and passionate musician. From an early age she developed a keen ear for music, learning the piano from the age of six. Soon after this she began learning the cello and clarinet, performing within a variety of ensembles. She was also an enthusiastic member of a chamber choir, performing at St. Paul’s cathedral and Notre-Dame, Paris (before the damage!). 

Anne-Marie studied both cello and piano at the University of Sheffield under the direction of Yolanda Wrigley and Kathryn Harris.  After graduating she moved to the south-west of England, to complete a PGCE at the University of Bristol graduate school. From here, she began a highly successful career in teaching music across secondary schools in Bristol and Gloucestershire.

Prior to forming JAM Duo, she was Head of Music at Churchdown School Academy where she enjoyed sharing her passion for music with students. After 16 years at Churchdown, Anne-Marie left teaching in Summer 2021 to pursue a career as a professional musician with Jules.
