The title "As Baile" can be translated as "away from home". A phonetic pronunciation: "Ass Bal-eh".
The song itself is all intonation, although you might say the intonation is "based" in Irish Gaelic. Enya sings "oró, horo, mo-ray he u way, he u way" and so on. The word "oró" is an interjection that could be translated as "oh!" or "oho!", but the rest of the song is intonation.
