uncoated bamboo flute
A bamboo flute that has not been lacquered or coated, often used in traditional Japanese music.
地無し管は、漆を塗っていない素の竹の音色が特徴です。
The uncoated bamboo flute is characterized by the natural tone of unlacquered bamboo.
Compound of 地無し (jinashi, 'without coating') + 管 (kan, 'pipe/tube'). The exact historical derivation is uncertain; the term describes a bamboo flute left in its natural state without lacquer.
