Kupuốt / Ku puốt (gender unknown)
Mouth organ with a gourd as wind chest
Raglay (Raglai, or Rai) people (provinces Ninh Thuận and Khánh Hòa, South Central Coast region, on the border of the Central Highlands]); 6 pipes in 2 sets (4+2); Blench states that "The Roglai [sic] hold the instrument at right angles to the body, so that the pipes project laterally rather than forward"; Having seen, however, only one and the same photo of such a posture (in Blench and other sources [➺ also the YouTube video to Ku puot]), I’m not convinced that this is common practice.
Gourd, with bamboo pipes (380-780 mm; Ø 20 mm).
