Lengjen (Lingjin) comes from Senegal, some specify this to the Casamance region. The notation information I have from Larry Morris' rhythm catalogue and some email discussion on the Djembé-L mailing-list. Thanks also to Peter Watson, from Nova Scotia, Canada on helping me finish the information. I compared this to a life recording of Lingjin that I once obtained. This recording shows a slow part with song and a quick part, obvious with dance.
