Boing drum?
What's the drum that is often used in yoga/calming sounds music, the kind that makes you think of waterfalls or the rain forest, that makes a "boing" sound. It reminds me of Donkey Kong Country but I don't know if it's actually in that music. Is it a real instrument? I know it is one of the voices on something such as a casio keyboard. Not a floor tom, it has a more pronounced "boing."
