I was almost inspired to take up the Telyn myself after an amazing weekend run by Harriet Earis A weekend of Welsh language and literature in Snowdonia - book now for 2019 events
She not only knows heaps about Welsh literature and presents it in an enthusiastic and interesting way, but is a talented harpist and very knowledgeable on the history of the telyn in Cymru. Her weekends in Snowdonia are an absolute treat.
As an aside, the Teifi Harp factory is just down the hill from where I live
