Ten Pieces I Prom: St Mary's Primary play their composition 'Equinox'

'Equinox' is a composition for three violins, inspired by Beethoven's Symphony No. 5. It was written by a 10-year-old pupil from Northern Ireland for herself and two friends. The piece was orchestrated for the BBC National Orchestra of Wales by Gareth Glyn and the girls were supported by violinists from the orchestra.
