کیirtan is a form of devotional singing in the Hindu and Sikh traditions, where participants chant or sing hymns and mantras that praise God or express spiritual themes. It often involves a call-and-response format, making it an interactive and communal experience. Typically performed in groups, کیirtan can take place in temples, homes, or during religious festivals. The use of musical instruments, such as the harmonium and dholak, enhances the experience, creating a vibrant atmosphere that encourages participation and devotion among attendees.
