The text and more than a hundred full-page color plates document 
Tibetan folk music (particularly work songs), and local life in Sman 
shod Valley, Sde dge County, Dkar mdzes Tibetan Autonomous Prefecture, 
Sichuan Province, China. Bo nyed, a local elder, describes the 
situation that motivated this timely documentation, "In the past we 
sang constantly, but now people don't sing no matter where they are or 
what they are doing. Now everyone is silent." The text includes richly 
contextualized and annotated transcriptions of the songs' Tibetan 
lyrics with English translations.
