The Rodolfus Choir is made up of singers aged from 16 to 25 who have been chosen from past and present members of the Eton Choral Courses for prospective choral scholars. Many members of the Choir are choral scholars, some are at music college, and most hope to make a career in music.

Since its foundation by Ralph Allwood in 1984, the Choir have toured extensively in Europe, and have also appeared throughout the United Kingdom at venues great and small, including St John's, Smith Square and some of the country’s most glorious cathedrals.

The Rodolfus Choir and Ralph Allwood are well-known for imaginative programming, and for presenting new music. The Rodolfus Choir’s recent CD recordings include music as diverse as Howells, Monteverdi, Grier, Tallis and the German Romantics.

The Choir is a regular contributor to BBC Radio 3’s Choral Evensong, and has featured on Classic FM, as well as appearing on BBC TV’s Songs of Praise and in the Channel 4 documentary Alex: A Passion For Life which followed preparations for the choir’s performance of Bach’s B Minor Mass at Cadogan Hall in April 2009.
