The hand of the Koto with a change of hands - Kaeteshikino Koto no Te

...In jiuta, when several different tetsuki (compositions for the shamisen) were made for the same piece, the second or subsequent te was called te.

In particular, those transferred to the koto and played in ensemble with the original shamisen piece are called kaede style koto no te.

*The following is a partial explanation of the term "kaede-shiki no koto no hand."
