People have been offered the chance to be an opera singer for the day at Glyndebourne in Sussex.
People were invited to join in with professional opera singers
The open day was part of celebrations being held across Europe to mark 400 years of opera.
Open day events at Glyndebourne, near Lewes, included backstage tours, make-up, music and costume workshops.
Films of productions were being shown throughout the day, and a performance by singers from the Glyndebourne Chorus was being staged.
People who wanted to sing were invited to join in with the Toreadors from Bizet's Carmen, led by professional singers and the opera house chorus master.
A spokesman for Opera Europa, which organised events on Saturday across Europe, said opera was "an art which for four centuries has taught European citizens to overcome national and linguistic barriers and to share a common heritage".
