Dyfed was born in Cardiff and spent his childhood tearing between carol concerts, choir rehearsals and eisteddfodau. He moved to Manchester to study singing and opera at the RNCM where he won numerous scholarships and prizes including a Peter Moores Foundation Scholarship to enable him to study opera at the Vienna Conservatoire.
After graduating, he continued his European Odyssey for a decade, moving between countries and working for many of the European Opera Houses and festivals.
In 2004 he married the mezzo soprano Carolyn Jackson and they moved to a village outside Cardiff. He now tries to be at home for his two young boys as much as possible, mixing his opera work for the WNO with a busy concert schedule. He enjoys running opera workshops and community singing projects in South Wales and beyond and is also in demand as a choral conductor and tutor.
