This song called "Langkor" revolves around taming oxen and is sung by Bhutanese farmers. As plowing with bulls is declining fast and being replaced by tractors and power tillers, it has become rare to find a farmer singing the song. In the past, the soothing poetic tunes of the Langkor would be heard while farmers tilled their land with oxen. Bhutanese traditionally tilled their land using a pair of bulls, the type of which often varied according to the location of the fields. Today, although mechanical tractors and power tillers have relieved the farmer and oxen of the pain of hard work, plowing no longer has the natural charm of connecting to the land and the animals.
