Jemma began playing the Cornet at the age of 8 with instrumental tuition given through Goodwick Brass Band. Jemma became a member of the Three Counties Youth Brass Band at the tender age of 12. The following year, she became a member of the National Youth Brass Band of Wales. Jemma was a member of the NYBBW for 8 consecutive years and played under the Musical Direction of James Watson, Robert Childs, Nicholas Childs and Edward Gregson.

In 2004 she was accepted to study music at the Royal Welsh College of Music and Drama and gained her Bachelor of Music degree in 2008. Whilst at RWCMD Jemma was also selected to represent Wales as a member of the European Youth Brass Band. Whilst at college she was lucky to have the chance to play with some amazing brass bands in South Wales and jumped at the chance to play with the likes of BTM, Burry Port, Tongwynlais, Flowers Band and The Cory Band.

Since graduating she has made sure that her performing abilities have been kept up to a high standard by playing with the Wantage Band, Jemma now holds the Solo Horn seat and is enjoying the new challenge. 

Jemma joined Cold Ash Brass in 2012. Under her leadership we won our first contest together in 2014. Our next venture saw us placing second at the L&SC regional contest meaning another place in the national finals in Cheltenham in 2015. Together, Jemma and the band qualified for promotion to the second section in 2018.
