The Huli people of Papua New Guinea’s Southern Highlands are known for a remarkable vocal tradition sometimes described as iBi calling or Huli yodeling. Instead of ordinary speech, these calls involve dramatic shifts in pitch, creating powerful, melodic sounds capable of carrying across the steep valleys and dense forests of the Highlands.
Historically, this style of vocal calling could serve a practical purpose, allowing people to communicate with relatives, exchange greetings, or send signals across long distances. In such rugged terrain, two people could be relatively close yet separated by thick vegetation, mountains, or deep valleys, making a strong, far-reaching voice an incredibly useful form of communication.
To outsiders, the calls can sound almost like music, which has helped recordings of the tradition capture attention around the world. Today, viral clips offer people a glimpse into just one fascinating aspect of the Huli’s much broader cultural heritage, which also includes distinctive language, storytelling, music, art, and ceremonial traditions.
