Oopoochawa or Opochawa, also known as quisanche is a type of mbira or lamellaphone from South America, popular in the areas of Montevideo, Uruguay and La Plata, Argentina.
The instrument consists of a wooden base with metal "tongues" that can be picked to produce a specific note.
The quisanche was brought to South America by Afro-Argentine immigrants in the late 1800s, and became quickly integrated into the folk music of the region.
