This song, is sung by many welsh artists. However, it is an ancient welsh folk song like many others, the original author is unknown (please correct me if I'm wrong), and is meant to be sung acapella. The chords I have written down are Sian James' version, but these may change according to the artists. There are also countless additional verses to this song, but I have included the most known ones. [Chords] Pan ro'n i'n rhodio mwynent eglwys gan chwylio am lle teg i orffwys trawn fy nhroed wrth fedd f'annwylyd mi glywn fy nghalon fach yn symud Haen o bridd a cherrig hefyd sy' rhwng y fi a chorff f'annwylyd a phedair 'styllen(astell) wedi'w hoelio pe bawn i well mi dorrwn honno Eisteddais lawr, dechreuais wylo Nes ddaeth rhyw ddyn diether heibio y cwyd dy ben a phaid ag wylo mi gei di gariad newydd eto Nid rwyf rhyw ddydd yn gweld obeithion Na chai chariad newydd eto mawr yw'r pwysau gennai am ei weled gweled rhoi pridd ar ferch mor laned Trwm yw'r plwm, a thrwm yw'r cerrig Trwm yw calon pob dyn unig 'does drymach beth dan haul na lleuad na chanu ffarwel i'n nghariad
