Taiko have been developed into a broad range of
percussion instruments that are used in both
Japanese folk and classical musical traditions. An early classification system based on shape and tension was advanced by
Francis Taylor Piggott in 1909. Taiko are generally classified based on the construction process, or the specific context in which the drum is used, but some are not classified, such as the toy
den-den daiko. With few exceptions, taiko have a drum shell with heads on both sides of the body, and a sealed resonating cavity. The head may be fastened to the shell using a number of different systems, such as using ropes. Taiko may be either tunable or non-tunable depending on the system used. Taiko are categorized into three types based on construction process.
Byō-uchi-daiko are constructed with the
drumhead nailed to the body.
Shime-daiko are classically constructed with the skin placed over iron or steel rings, which are then tightened with ropes. Contemporary
shime-daiko are tensioned using
bolts or
turnbuckles systems attached to the drum body.
Tsuzumi are also rope-tensioned drums, but have a distinct hourglass shape and their skins are made using deerskin.
Byō-uchi-daiko were historically made only using a single piece of wood; they continue to be made in this manner, but are also constructed from staves of wood. Larger drums can be made using a single piece of wood, but at a much greater cost due to the difficulty in finding appropriate trees. The preferred wood is the
Japanese zelkova or
keyaki, but a number of other woods, and even
wine barrels, have been used to create taiko. an elongated drum that is roughly shaped like a wine barrel.
Nagadō-daiko are available in a variety of sizes, and their head diameter is traditionally measured in
shaku (units of roughly 30 cm). Head diameters range from . are the smallest of these drums and are usually about in diameter. The is a medium-sized

Ō-daiko means "large drum" and for a given ensemble, the term refers to their largest drum. have a tube-shaped frame. Like other
shime-daiko, drum heads are attached by metal hoops and fastened by rope or cords.
Okedō can be played using the same drumsticks (called
bachi) as
shime-daiko, but can also be hand-played.
Okedō come in short- and long-bodied types.
Tsuzumi are a class of hourglass-shaped drums. The drum body is shaped on a spool and the inner body carved by hand. Their skins can be made from cowhide, horsehide, or deerskin. While the
ō-tsuzumi skins are made from cowhide,
ko-tsuzumi are made from horsehide. While some classify
tsuzumi as a type of taiko, others have described them as a drum entirely separate from taiko. Taiko can also be categorized by the context in which they are used. The
miya-daiko, for instance, is constructed in the same manner as other
byō-uchi-daiko, but is distinguished by an ornamental stand and is used for ceremonial purposes at
Buddhist temples. The (a
ko-daiko) and (a
nagadō-daiko with a cigar-shaped body) are used in
sumo and festivals respectively. by

gagakki, are used in the Japanese theatrical form,
gagaku. The lead instrument of the ensemble is the
kakko, which is a smaller
shime-daiko with heads made of deerskin, and is placed horizontally on a stand during performance. A
tsuzumi, called the
san-no-tsuzumi is another small drum in gagaku that is placed horizontally and struck with a thin stick. are the largest drums of the ensemble, and have heads that are about in diameter. During performance, the drum is placed on a tall pedestals and surrounded by a rim decoratively painted with flames and adorned with mystical figures such as
wyverns.
Dadaiko are played while standing, and are usually only played on the
downbeat of the music. The is a smaller drum that produces a lower sound, its head measuring about in diameter. It is used in ensembles that accompany
bugaku, a traditional dance performed at the
Tokyo Imperial Palace and in religious contexts.
Tsuri-daiko are suspended on a small stand, and are played sitting down.
Tsuri-daiko performers typically use shorter mallets covered in leather knobs instead of
bachi. They can be played simultaneously by two performers; while one performer plays on the head, another performer uses bachi on the body of the drum. The larger
ō-tsuzumi and smaller
ko-tsuzumi are used in the opening and dances of
Noh theater. Both drums are struck using the fingers; players can also adjust pitch by manually applying pressure to the ropes on the drum. The color of the cords of these drums also indicates the skill of the musician: Orange and red for amateur players, light blue for performers with expertise, and
lilac for masters of the instrument.
Nagauta-shime daiko or
uta daiko are also featured in Noh performance. Many taiko in Noh are also featured in
kabuki performance and are used in a similar manner. In addition to the
ō-tsuzumi,
ko-tsuzumi, and
nagauta-shime daiko, Kabuki performances make use of the larger
ō-daiko offstage to help set the atmosphere for different scenes. ==Construction==
