The Morriston Orpheus is considered one of the premier choirs in Wales since its establishment in 1935 under the direction of the late Ivor E Sims.
Having previously achieved a fine reputation in national competitions, the choir is now renowned as a highly successful concert choir and has not been heard on the competitive stage for many years.
Alwyn Humphreys MBE was appointed musical director in 1979, and he broadened the repertoire to include popular as well as classical styles of music. Variety is now the hallmark of the choir's performances, and they have performed with T'Pau and The Alarm.
In 2005 the choir appointed Sian Pearce to replace Humphreys who had decided to retire. Sian left the Choir in June 2007 and the Choir's respected former accompanist, Joy Amman Davies, took on the role of Musical Director.
New York's Carnegie Hall and the Sydney Opera House are among the prestigious venues they have performed in during their numerous overseas tours. In 2008, they gave a concert in a very unusual location - the control room of the large Hadron collider at CERN in Geneva, where the project director, Dr Lyn Evans, is a vice president of the choir.
A further important contribution to Welsh musical life is made through the Morriston Orpheus Choir Supporters' Association which annually organises its own Young Welsh Singer of the Year Competition offering a significant financial award.
The contest is open to Welsh students studying singing at any college or university in the United Kingdom. Previous winners have included international stars Rebecca Evans and Bryn Terfel, both of whom are vice presidents of the association.
