BBC Philharmonic debut Manchester's mood music

The BBC Philharmonic Orchestra have debuted a composition by the BBC Young Composer of the Year.

The work was based on a mood experiment in Manchester in which 20,000 people were tested for the Great Manchester Health Experiment.

That information was then given to composer Jack Sheen who used it to create a piece for the orchestra.
