During YTT we do many things except yoga. For example, singing Kirtan.
Kirtan is a Sanskrit word that means "narrating, telling, describing" of an idea or story. It also refers to a genre of religious performance arts, connoting a musical form of narration or shared recitation, particularly of spiritual or religious ideas.
With roots in the Vedic tradition, a kirtan is a call-and-response style song or chants, set to music, wherein multiple singers recite or describe a legend, or express loving devotion to a deity, or discuss spiritual ideas. It may include dancing or direct expression of bhavas (emotive states) by the singer. Many kirtan performances are structured to engage the audience where they either repeat the chant, or reply to the call of the singer.
A Kirtan performance includes an accompaniment of regionally popular musical instruments, such as the harmonium, shruti box, the tabla (one-sided drums), the mrdanga (two-sided drum) and flute.
