Sey began playing the piano at the age of seven and has since developed a lifelong dedication to music. Over the years, she has performed extensively at a wide range of events, including concerts, weddings, and funerals, gaining broad experience as a versatile and sensitive performer. She holds a Grade 8 qualification in piano, a Bachelor’s degree in Music (Piano) with Honours, and a Master’s degree in Music.

Sey is also actively involved in her local musical community, serving as the pianist at her church in Hendon every Sunday and singing as a member of the choir at St Mary’s Church, Hendon. Alongside live performance, Sey maintains a YouTube channel where she shares piano performances with a wider audience. At present, Sey is focussed on teaching music as widely as possible, imparting her knowledge to the next generation of musicians, and pursuing ongoing research in music—particularly piano studies—alongside teaching and performance work.
