Dafydd, who now lives in Cardiff, has been composing music since he was at school, and has been in several bands. He also competed in the Cân i Gymru competition in 2018 with the song 'Dwi'm yn dy nabod di'.
This year, his song 'Chdi sy’n mynd i wneud y byd yn well', will be performed by Bryn Hughes Williams.
The competition, broadcast live from the Arts Centre, Aberystwyth, on 3 March on S4C, will be presented by Elin Fflur and Trystan Ellis-Morris.
Gwenno Pritchard, A Level Music lecturer at Coleg Meirion-Dwyfor said,
"We love hearing about the success of our former students, and I'd like to congratulate Dafydd on his achievement of reaching the final 8 of the Cân i Gymru competition. We are looking forward to hearing the song and and wish him all the best."
