Follow Morley Memorial primary school, Cambridge as they trial a 10-week singing package from conductor and musician Suzi Digby of The Voices Foundation.
The foundation, founded 14 years ago, normally offers schools a year long programme to improve singing and understanding of music.
It claims participation boosts self confidence, enhances mental alertness and improves social cohesion within the school.
The cameras follow Suzi and the teachers as they put the theory into practice and try to squeeze a year's work, into 10 weeks.
It's not always an easy ride, and the programme conveys some of the realities of taking on the extra workload.
