Since its founding in 1937 by W. S. Gwynn Williams, Gwynn Publishing Company has been at the forefront of the music publishing industry in Wales, with particular emphasis on the vocal and choral repertoire, enhancing the performing material for the thriving choral tradition in the UK.

Gwynn's publications are performed regularly in high profile concerts, together with regular broadcasts and recordings of our music by a long list of distinguished artists, including the London Welsh Male Voice Choir, the renowned coloratura soprano Charlotte Church (Songs of the Three Birds by Dilys Elwyn-Edwards), and the celebrated baritone Bryn Terfel (the song cycle Adlewych by Meirion Williams).
