A Kora is an African stringed instrument (like a very complicated guitar). It has between 10-23 strings and is one of the most melodic instruments of Western Africa.
It was originally used by the Griot family to accompany folk songs.
The simple repetitive rhythms and improvisations that are used are called brimintingo
The word used to describe the melody that is played on the Kora is kumbengo however, when there are two melodies the main melody is called the kumaura and the secondary melody is called the kutsinhira
