The na─čara (also called koltuk davulu) is a Turkish folk drum or percussion instrument. It is placed under the arm and beaten with the hands. It is longer compared to the regular drums and its diameter is smaller. This is the same as the Azerbaijani naghara. There is a proverb in the Azerbaijani language that says "toy-dan-sora-naghara!" This literally means after the wedding ceremonies naghara! This instrument helped the doctors to deal with bad mood, melancholy, intellectual and physical exhaustion, as well as low blood pressure. It was considered that the Naghara could substitute for some medicinal plants and tones like spicy cloves. The rhythmic beating of the naghara is believed to lead to the strengthening of the heart. The naghara is described in the Early Middle Age Azerbaijani literary epic, "Kitabi Dada Gorgud" (Book of Dede Korkut) (The Book of my Grandfather). Instruments resembling the Naghara were also well known in ancient Egypt. Thus, according to the rich scientific and musical heritage of our ancestors, it seems that not only did they listen to music for enjoyment and entertainment, but they perceived music a potent force in the prevention and treatment of various diseases
