Their repertoire includes several ancient songs of which the oldest may be "Lambang", which praises music. Other songs praise ancient kings and heroes, especially Sunjata Keita ("Sunjata") and Tutu Jara ("Tut Jara"). Lyrics are composed of a scripted refrain ("donkili") and an improvised section. Improvised lyrics praise ancestors, and are usually based around a surname. Each surname has an epithet used to glorify its ancient holders, and singers also praise recent and still-living family members. Proverbs are another major component of traditional songs.
