Krar in the context of "Pentatonic scale"

Bench (Bencnon, Shenon or Mernon, formerly called Gimira) is a Northern Omotic language of the "Gimojan" subgroup, spoken by about 174,000 people (in 1998) in the Bench Maji Zone of the South West Ethiopia Peoples' Region, in southern Ethiopia, around the towns of Mizan Teferi and Shewa Gimira. In a 2006 dissertation, Christian Rapold described three varieties of Bench (Benchnon, Shenon, and Mernon) as "...mutually intelligible...varieties of one and the same language". Bench is the ancestral language of the Bench people.

In unusual variance from most of the other languages in Africa, Bench has retroflex consonant phonemes. The language is also noteworthy in that it has been claimed to have six phonemic pitch levels in its tone system, one of only a handful of languages in the world that have this many, though it has since been reanalized with five levels. Bench has a whistled form used primarily by male speakers, which permits communication over greater distances than spoken Bench. The whistle can be created using the lips or made from a hollow created with both hands. Additionally, this form of the language may be communicated via the 5-stringed krar.
