If you have never heard Baïlèro ("The Shepherd's Song") by Joseph Canteloube, I recommend taking six minutes to give it a listen. Baïlèro, quite simply, is one of the most beautiful songs ever composed.
Baïlèro is sung in Auvergnat, which is a dialect of the Occitan language from southern France. Occitan is rarely heard today, and the French government refuses to give it any official recognition or status, claiming it is merely a dialect of the French language. Occitan is actually a Romance language that is much older than French.
Between 1923 and 1930, Canteloube wrote a collection of songs in the Auvergnat dialect. Baïlèro is the most famous of those songs.
