The Qoltuq nagara of Azerbaijan (Armpit drum) (Armenian: Դհոլ, Georgian: დოლი, Azerbaijani: Qoltuq nağara) is a folk drum with double head that is played on one side with the bare hands.

The nağara (also called koltuk davulu) is a Turkish folk drum or percussion instrument.

The body consists of a hollow wooden cylinder covered with leather tightly attached to it with iron rings.

The doli is often combined with other regional instruments including the chonguri, the chiboni, the salamuri, the buzika and the duduki.

[2] This instrument helped the doctors to deal with bad mood, melancholy, intellectual and physical exhaustion, as well as low blood pressure.

In Circassia and Dagestan, this type of cylindrical folk drum (with two skin heads) is called the baraban.
