A traditional reed flute from northeastern Thailand. It produces sound by exhaling and inhaling air through the mouthpiece of a bundle of multiple bamboo pipes. Complex harmonies and rhythmic performances can be created with breath and finger movements. This instrument is a predecessor to the Japanese sho. Purchased in 2000 at a musical instrument store in Bangkok. There is a crack in the end. Please check the photos. I have confirmed that sound can be produced by closing and opening all the holes. All notes can be played. Length: 988mm Width: 110mm Height: 26-32mm Please understand that there is a crack and purchase with no returns or refunds.
