Even though I grew up in Wales (albeit in Anglicised Penarth) and as an adult became very interested in traditional Welsh culture, I had never come across
canu'r pwnc until my wife bought me a copy of The Rough Guide to Wales CD. The CD is a compilation of a wide variety of Welsh folk music, though not of Welsh music in a broader sense since it lacks any cerdd dant or male voice choirs. Canu'r pwnc is "a very ancient form of choral singing that... occurs in Pembrokeshire and western Carmarthenshire. 'Canu'r pwnc' is the chanting of scriptural text and usually takes place around Whitsuntide. The rhythmic structure and harmonisation sounds startling to modern ears, and yet this form of declamatory singing is very common and well-known throughout the region. The singing can last continually for an entire weekend, with people from different villages taking up the baton after a period to keep up the momentum."
The selection on the Rough guide CD was recorded in Maenclochog in Preseli in 1967. They seem to be singing the genealogy from the beginning of Matthew or Luke. The singing sounds like the most pagan thing you ever heard. Canu'r Pwnc literally means 'singing (bible) study.' The people from Capel Rhywilym are prbably Welsh Baptists. But surely they were picking up on a style of singing that goes back at least to medieval times.
There's an piece of Canu Pwnc on the BBC website, as part of a 1967 BBC Wales broadcast on Carmarthenshire. You might want to close your eyes when you listen to it for the first time, since the mysterious chant contrasts badly with the angelic schoolchildren in shirts and ties who are singing it on this clip ({if I remember rightly.)

http://www.theatre-wales.co.uk/critical/critical_detail.asp?criticalID=98He mentions Canu Pwnc: "Lampeter-based archaeologist Michael Shanks has written, 'Archaeology is about some very basic and mundane things: grubbing around in decayed garbage, recovering traces of things and processes which go largely unnoticed today - what happens to broken bits of pot, to things that get lost, abandoned buildings, rotted fences, microbial action. A creeping, mouldering under-side of things'.(2) Archaeology leads equally to thoughts of ruin, decay, putrefaction and of aging, erosion, wearing...Which is perhaps why I found as much in the struggles of the canu pwnc group from Rhydwilym chanting John 1:1 - 'Why do you move from a minor third to major third in your chant?', asked the Vietnamese musicologist. 'Because we can't sing in tune', replied the aged choir--as in the practised harmonies of the equally aged Bulgarian 'Grannies' of Bistritsa'."
Many of the traditional forms of singing give an impressions of great age simply because the singers are of great age! This is often true of Irish sean-nos singing too. Still, this is a comic moment, a Vietnamese musicologist over in Wales being fascinated by an unusual musical transition that turns out to simply be singing out of tune.
