The sound of Oyme is primarily based on the polyphonic female singing (mostly in Erzya language, but other Finno-Ugric and Northeast Caucasian languages are used as well).

A more modern, electronic kind of sound is also used on some tracks.

Based on their own field trips to villages with ethnic populations, they reconstruct folk celebrations and rituals, traditional musical instruments, and national costumes.

Their live performances typically evolve into an interactive ritual that involves the audience, which is a characteristic feature of Oyme.

Their music is also used to announce fight entrances of MMA wrestler Vladimir Mineev.
