Hindustani classical music is a traditional form of Indian music that originated in the northern regions of India. It is characterized by its improvisational nature and the use of ragas, which are melodic frameworks that guide the performance. The music often features instruments like the sitar, tabla, and harmonium, and it can be performed vocally or instrumentally. The performance of Hindustani classical music typically involves a slow introduction called alap, followed by a more rhythmic section known as gat. This genre emphasizes emotional expression and spiritual connection, making it a significant part of India's cultural heritage.
