There has been a 25% drop in pupils studying GCSE music at schools in England over the last fifteen years, despite an uptick in the most recent stats.
That is partly down to the introduction of a progress measure for schools called the English Baccalaureate in 2010, which assessed schools based on how many pupils took English, maths, sciences, geography or history and a language - and how well they performed.
The government recently announced that it would be changing the school curriculum in England to make it easier for more schools to offer arts subjects like music.
There has been some improvement in recruiting new music teachers this year, but the levels still fall 35% short of government's target for trainee music teachers in the most recent stats.
James Manwaring, president of the Music Teachers Association - which represents music teachers across both state and private schools - says every school should have a choir.
"All you need is a room and you need someone to lead it and you need students," says James, who is also the director of music at Windsor Learning Partnership - a multi-academy trust of six state schools.
"It's a shame to think some state schools aren't capitalising on that."
He says changes to the school curriculum in England are "very exciting" for boosting music in schools, but says more funding and resources will be needed - "as well as retaining the wonderful music teachers we have out there".
