For the first time in 1,000 years, the melodic voices of a girls’ choir filled the air at Canterbury Cathedral in Canterbury, England, Saturday.

Prior to the girls’ choir debut, Canterbury Cathedral had only featured its all-male chorus, although female singers from visiting choral groups did occasionally perform over the years.

While the boys who sing in the all-male chorus practice every day and live at the cathedral, the girls’ choir is comprised of local young women who come together to practice once a week.

The girls’ choir, featuring 16 girls between ages 12 and 16, is scheduled to perform when the boys’ choir is on school breaks. However, the dean of Canterbury, Robert Willis, said in an AP story that eventually the girls’ choir would be featured more prominently.
