The khomus is an ancient musical instrument of the peoples of the Sakha Republic (Yakutia), which has been in existence for more than a thousand years. Originally, the khomus was used as a shamanic instrument, as its sacred music was an indispensable part of various rituals. For Yakutia, the khomus is a symbol of the entire nation.

In ancient times, the material for making the khomus was wood struck by lightning, which was believed to "play." Nowadays, the instrument is made from metal. Its characteristic rattling sound is created by a vibrating "tongue." There may be one or several tongues. To play the khomus, the main goal is to achieve harmony of sound, to listen to the music not only with the ears but with the whole body, fully concentrating on the performance.

The uniqueness of the khomus gifted to Dimash lies in the fact that it is an exact replica of the khomus that went to space. It was crafted by Yakut master Revory Chemchoev.

In 2018, Revory Chemchoev appeared in a film about the khomus, Strange Sounds of Happiness, by Italian director Diego Pascal. It was Chemchoev who was entrusted with making the khomus that was later taken into space. There are only 10 space khomuses in the world.
