Back when we were kids, my sister and I didn't have alarm clocks. The parents (well, usually just Mom) would get up at some unearthly hour to go downstairs and do those things that parents do, like make vast quantities of tea. As morning wore on, this Nepalese yak bell would sound the call to get up. Despite it's appearance, it's actually quite sonorous and musical.
It was a far more pleasant sound to wake up to than my modern alarm, lurking in the background.
