摘要

The kettledrum has a clamp (24) at the tension piece (12) and is gripped at the fine tuning element (14). The clamp blocks the movement of the tension piece relative the fine tuning element according to a decrease in the tension of the drum skin (2), but allows movement of the tension piece relative to the fine tuning element according to tensioning in the tensioner (10). Devices (32,34,35,37) are provided to unbolt the clamp
