Qawwali is a form of Sufi devotional music that originated in the Indian subcontinent. It is characterized by its powerful vocal performances, rhythmic handclapping, and the use of instruments like the harmonium and tabla. Qawwali songs often express themes of love, spirituality, and devotion to God or the Prophet Muhammad. Typically performed at Sufi shrines and during religious gatherings, Qawwali aims to create a spiritual atmosphere that encourages listeners to connect with the divine. The performances can last for several hours, engaging the audience through call-and-response patterns and emotional expression, making it a unique and immersive experience.
