The sound of kobyz

Kazakh national instrument Kobyz
Kobyz has a double bucket body, a short, arched neck and a large flat head. The body is usually made of walnut, birch, pine, juniper. It consists of a hollowed-out double hemisphere, to which a handle is attached from above, and a stand from below. Part of the body is covered with a camel skin membrane. Two strings are twisted from twisted horsehair. The total length of the instrument is 60-73 cm.
In ancient times, the instrument was completely made from a single piece of wood. An oblong-bucket-shaped body made of a single dug-out piece of birch is connected to a neck with a figured head with pegs. Deca made of calfskin semi-open. Strings of untwisted horsehair. The bow also uses horse hair. Range - 2.5 octaves. There are 2 types of Kyl-kubyz - with a straight neck and with an onion-shaped neck. The instrument is approximately 650-800 mm long, rests on the floor with a long pin coming out of the body or is held by the performer's knees.
They play the kobyz with a short bow, squeezing it at the knees (like a cello). This instrument was used in ancient times by steppe baksy (shaman-healers) for various rituals.
