Oliver Morrell joined the cathedral as Junior Organ Scholar in October 2018 and in October 2020 was promoted to Organ Scholar. Under the direction of Daniel Cook, he regularly accompanies and conducts the various choirs in services and has daily responsibilities teaching the probationers and choristers.

Born in Kent, and educated at St Olave's Grammar School, his formative musical training came from the five years he spent as a Chorister at the Queen's Chapel of the Savoy. Whilst at school, he founded an early music group and directed the Chapel Choir for four years. He also played the organ at weekly whole-school assemblies and served as répétiteur for various theatrical productions.

From school, he went on to hold the Tenor Choral Scholarship at Gloucester Cathedral. He studied with Bronwen Mills and sang with the Cathedral Choir at the daily services, under the direction of Adrian Partington. He also gained experience regularly directing rehearsals of the other Choral Scholars, accompanying rehearsals of the Saint Cecilia Singers and assisting with the running of the Cathedral Junior Choir and Primary School Outreach Programme.

Alongside his current Cathedral duties, he is Assistant Musical Director of the Durham Singers and an accomplished solo performer, having given recitals as an organist, singer and pianist. He has also acted and sung in theatrical productions at university and school. As a composer, he has had works premiered at the London Festival of Contemporary Church Music.
