Khamaj is a Hindustani classical music raga within the Khamaj thaat which is named after it. Many ghazals and thumris are based on Khamaj. It utilises the shuddha (pure) form of Ni on the ascent, and the komala (flat) form of Ni on the descent, creating a key asymmetry in compositional and improvisational performance. This raga has been explored more in the lighter forms of Hindustani Classical Music such as Thumri, Tappa etc. Yet a many compositions in Dhrupad and Khayal are found as well.
This Raag is an ideal melodic format for both type of Shringars, Vibralambh (Separation) and Uttan (Union) Shringar. For this reason, there are more Thumri compositions in this Raag. The mood is light and enthralling but not sedate. With a husky voice that emits the emotion of painful separation and with Khatkas and Murkiyan, the Raag mood is well brought out, decorated with diverse Thumri styles of Panjab, Lucknow and Banaras Gharanas.
