Japan has a wide range of transverse flutes, proof one might say, of their popularity.
In gagaku, Japanese imperial court music there are three types of transverse flute – ryūteki, komabue and kagurabue – with the most common, ryūteki, used in “music of the left” (tōgaku) and saibara, a genre of accompanied vocal music from the Heian court (9th-12th centuries CE). Transverse flutes used in Japanese Noh plays are called nōkan, and have an irregular scale due to the unique construction of the throat of the instrument. Shinobue, also called ‘bamboo flutes,’ used in kabuki theatre and folkloric performance arts are of simple bamboo construction, yet come in a range of lengths. Both ryūteki and nōkan have seven finger holes, komabue and kagurabue have six finger holes, and shinobue has either six or seven finger holes.
For Japanese transverse flutes there is a mnemonics technique, shōga, to memorize by singing a melody and chanting such syllables as o-hyā-rā.
