Evan Morgan (b. Tyn-dre, Morfa Bychan, Wales, 1846; d. Portmadoc, Wales, 1920) was a furniture maker by trade in Morfa Bychan in the Lleyn Peninsula. He took an interest in music at a young age, however, and became well-known in Wales as a singer and poet. He composed some hymn tunes and arranged folk tunes for the brass band in Portmadoc. His tune TIDDYN LLWYN was first published in the second appendix (1890) to Ieuan Gwyllt's Llyfr Tonau Cynulleidfaol (The Book of Congregational Tunes, 1859). The tune's phrases balance each other very well; the final phrase resolves the rhythmic energy and harmonic color of the initial lines. Part singing goes well with a moderate tempo.
