Hindustani Classical music is influenced by ancient Hindu musical traditions, Vedic philosophy (Rigveda, Yajurvedic chants), Natya Shastra (gives information on scales, melodic forms, tala and musical instruments) and also by the Persian elements. The major vocal forms associated with Hindustani classical music are the dhrupad, khayal, thumri, tappa, and tarana. Important Gharanas are Gwalior Gharana (oldest), Agra Gharana (founded by Khuda Baksh) and Jaipur Gharana (directly took off from Dhrupad), Rampur Saheswan Gharana (Uttar Pradesh).
