This piece was created by four postal workers in Ghana.
This particular piece is a field recording that was recorded by James Koetting in 1975. The music was created by the postal workers canceling stamps in the University of Ghana post office in Ghana. The whistled part is from the hymn "Bompata," by the Ghanaian composer W.J. Akyeampong (b. 1900). This type of music is created daily as a normal part of life for the Africans in Ghana.
