"They are listening to music."
Translation:Maen nhw'n gwrando ar gerddoriaeth.
For the land of bards and singers, Welsh sure has a long and hard-to-remember word for "music" :)
Also the root is 'cerdd' which is an 'ode, poem' or 'song'
Poetry and singing are very much intertwined in the Welsh tradition of the Eisteddfod.
