Devotion, beauty and the opulence of love are the basis of Raga Khamaj. It has been a popular choice for film music as well. Raag Khamaj is a late evening raaga and is brought out rather elegantly in the light classical form of thumri.
It is also a specific raaga within the Khamaj thaat. Khamaj is one of the ten Thaats (parent scales) of Hindustani music.
