Her musical influences were quite eclectic – her father had an extensive record collection with a large black music content, as a young child she listened to classical music on The Magical Music Box, and she was taken to see Jools Holland and his Big Band on her 11th birthday, whilst all the time listening to a wide array of music of her choice. Duncan first sang in public at age 10 in Junior school, and at age 15 she won the year 11 music competition at her Secondary school, singing and playing an Alicia Keys cover. She had also been writing her own songs from quite an early age. She left school to attend New College Nottingham where she obtained a BTECHNC in music in 2007.
