Taiko. It's Japanese for big drum. It's a recent thing, started post WW2. Lots of drums, different shapes, a troupe of drummers. Body posture and group coordination play a big part, holding your back straight, raising your arms in unison and letting gravity's force help you hit the skins with the sticks. Yamato are terrific, fabulous rhythm, powerful sound, great costumes, lots of flailing arms hitting the skins, a joy to watch and to listen to...
