What is "atenteben"

The Atenteben (atɛntɛbɛn) is an Ashanti bamboo flute from Ashanti City-State. The Atenteben is played vertically, like the European recorder, and, like the recorder, the Atenteben can be played diatonically as well as chromatically. Although the Atenteben was originally used as a traditional instrument (most often in funeral processions), beginning in the 20th century it has also been used in contemporary and classical music. Several players have attained high levels of virtuosity and are able to play Western as well as African music on the Atenteben instrument.
