Jangar is performed by jangarchi, specialist singers analogous in social role to the manaschi of the Manas tradition, who learn and perform its cantos through sustained oral training rather than from a written libretto, often accompanying their recitation on traditional stringed instruments. The epic's transmission has been shaped significantly by the modern history of the Kalmyk people, including a forced deportation to Siberia and Central Asia during the Second World War, after which sustained cultural effort went into recording and preserving the epic tradition among a scattered population.
Comparative folklorists have long grouped Jangar together with the Epic of Manas and the Epic of King Gesar as part of a broader family of heroic oral epics native to the steppe and highland zones of Inner and Central Asia, sharing structural features such as the paradise like homeland under recurring threat, though each tradition remains distinct in language, named heroes and specific performance practice.
Post-Soviet Kalmykia has treated the recitation and study of Jangar as a marker of cultural continuity following decades of deportation and dispersal, supporting collection projects, festivals centered on the epic and its formal inclusion in regional cultural heritage recognition, alongside comparable efforts among Oirat communities living beyond Kalmykia's present day borders.
