Tonight's Music

This is an example of canntaireachd being sung, or chanted, by Rona Lightfoot.

From Wiki:

Canntaireachd (Scottish Gaelic: literally, "chanting") is the ancient Scottish Highland method of noting classical pipe music or Ceòl Mòr by a combination of definite syllables, by which means the various tunes could be more easily recollected by the learner, and could be more easily transmitted orally. Nowadays, however, pipers tend to use standard musical staff notation to read and write various tunes, and anyone attempting to read this particular system needs some familiarity with Scottish Gaelic phonetics. It does still linger on in one or two places however. In general, the vowels represent the notes, and consonants the embellishments, but this is not always the case, and the system is actually extremely complex, and was not fully standardised.
