Kirtan is a meditational and devotional chanting experience usually set to music.
Kirtan refers to chanting – one of the main practices of yoga. Chanting is a form of meditation that is joyful and fun. Classic Indian instruments, such as the harmonium and drum accompany the chant, while simple Sanskrit mantras are repeated in a call-and-response fashion, from the leader to the group, building in energy and tempo.
Kirtan or Kirtana is a Sanskrit word that means "narrating, reciting, telling, describing" of an idea or story.
