Today is the 100th anniversary of the Representation of the People Act 1918, a piece of legislation that enabled all men and some women over the age of 30 to vote for the first time.
It would be another 10 years before UK women won the right to vote on the same terms as men. Still, 1918 was a seismic moment for the Women's Suffrage movement, which was led by tireless campaigners like Emmeline Pankhurst.
BBC Radio 3 is marking the centenary with a special choral commission (arranged for SSAA, SATB, or single-melody) written by two of Emmeline Pankhurst's descendants: composer Lucy Pankhurst and author Helen Pankhurst.
Radio 3 wants as many amateur musicians as possible to sing the work in 2018. They're calling choirs to learn the The Pankhurst Anthem and perform it at their concerts throughout the year, and to share their progress with the Radio 3 Breakfast team.
You can listen to the BBC Singers performing The Pankhurst Anthem and download and print a full score on the BBC Breakfast website.
