When Finn asks his men what music they thought the best, each says his say, but Oisin answers, "The music of the woods is sweetest to me, the sound of the wind and of the blackbird, and the cuckoo and the soft silence of the heron." And Finn himself, when asked what was his most beloved music, said first that it was "the sharp whistling of the wind as it went through the uplifted spears of the seven battalions of the Fianna," and this was fitting for a hero to say.

But when the poet in him spoke, he said his music was the crying of the sea-gull, and the noise of the waves, and the voice of the cuckoo when summer was at hand, and the washing of the sea against the shore, and of the tide when it met the river of the White Trout, and of the wind rushing through the cloud.

And many other sayings of the same kind this charming and poetic folk has said concerning those sweet, strong sounds in Nature out of which the music of men was born.
Again, there is not much music in the Mythological Tales.

Lugh, it is true, is a great harper, and the harp of the Dagda, into which he has bound his music, plays a music at whose sound all men laugh, and another so that all men weep, and another so enthralling that all fall asleep; and these three kinds of music are heard through all the Cycles of Tales.

Yet when the old gods of the mythology became the Sidhe,[7] the Fairy Host, they--having left their barbaric life behind--became great musicians.
