Today I have chosen an excerpt (the full version is 9:44 long but not availiable on YouTube) from "Ceann Drochaid' Innse-breiridh (The End of Inchberry Bridge)", a traditional Hebridean Scottish Gaelic song preserved in "Colin Campbel's Instrumental Book 1797". Due to a unique method of notation which is nearly unintelligible, the Hebridean Gaelic music was restored in an attempt of what is called music archaeology. The piece is musically performed by Barnaby Brown, Bill Taylor, and Clare Salaman as part of the European Music Archaeology Project. If the lyrics appear unintelligible this is no wonder, for they are canntaireacht, the traditional Gaelic method of vocalising bagpipe music, playing a bagpipe with the human voice instead of the actual instrument, so to say.
