The tambura is the South Indian counterpart of the North Indian tanpura. It is a drone instrument made of jackwood. There are four strings which cross a bronze bridge. While the strings are tuned fifth, upper tonic, upper tonic, and tonic, the tuning hardly ever changed, even for ragas that lack a fifth.
