The title "As Baile" can be translated as "away
from home".
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.
