Kafi is an important raga in Hindustani classical music. This raga corresponds to Kharaharapriya in Carnatic music.
Vishnu Narayan Bhatkhande classified most ragas into ten thaats; Kafi thaat is one of them. The raga Kafi is the principal raga of its thaat. It is a more recent raga; according to Bhatkhande, the name of the raga first appears in the Raga Tarangini of Lochana Pandit, who lived in the Mithila district around the 15th Century CE.
Raga Kafi has a direct lineage with the folk music of India. Folk music in Tappa, Hori, Dadra, Kirtan and Bhajans from different parts of India have been composed in this raga.
Nowadays, quite a few variations of Kafi exist. Contamination with vivadi swaras are judiciously used to increase the listening pleasure. This mixing has given rise to Mishra Kafi. Hence, a pure form of Kafi is seldom heard in recent performances.
Kafi is a sampoorna-sampoorna or heptatonic raga, with komal (lowered) Gandhar (g) and Nishad (n).

Pancham(P) is the vadi swara and Rishabh (Re) is the samavadi swara.
