The kakko is a double-reeded drum that is from Japan. One way
in which the musical instrument varies from the normal taiko drum is in the way
that it is manufactured taut. Just like the Shime-Daiko and tsuzumi, the skin
of the heads are 1st spread over metal hoops before they are placed
on the body of the instrument, trying them on each other tightening them and
making them taut. Kakko drum are often placed on their sides on stands so that
the musical instrument can be played with the use of stick known as bachi on
the two heads. The musical instruments have been used in taiko groups, though
they are also used in older court music of Japan known as gagaku.
The musical instrument is derived from the Chinese jiegu, a
musical drum that is popular in China during the Tang Dynasty, as the Korean
galgo.
