Uakti (WAHK-chee) is a Brazilian instrumental musical group that is composed of Marco Antônio Guimarães, Artur Andrés Ribeiro, Paulo Sérgio Santos, and Décio Ramos. Uakti is known for using custom-made instruments, built by the group itself.
The name of the group comes from a Tukano native South American legend. Uakti was a mythological being who lived on the banks of the Rio Negro. His body was full of holes, which, when the wind passed through them, produced sounds that bewitched the women of the tribe.
