With a number of choral and vocal commissions to his name, a reputation for imaginative, stylistically informed organ-playing, and the warmest of piano accompaniments, Meirion enjoys a busy and varied musical life. A scholar of the Royal Academy of Music, his church music portfolio includes Westminster Abbey, Brecon, Liverpool Metropolitan and Winchester cathedrals, and the Birmingham Oratory.

He is an official piano accompanist to the National Eisteddfod of Wales, and his own music is published by SAIN, Novello, and World Library Publications in Chicago.
