Ms [Lleuwen] Steffan, from Sling, near Tregarth, Bangor, first became interested in hymns after finding a hymn book in her grandmother's attic.
"I knew the words off by heart because I used to sing them like a Polly parrot, but I had never thought what they actually meant," she said.
"There was a feeling that something big was happening, there was a revolution behind these hymns.
"The message is ageless, no matter if you believe in a religion or not.
"You can't fail to be touched by the strength of feeling in the words, and understand that the people who wrote them experienced something real," she added.
