Khamaj

Khamaj is one of the ten Thaats (parent scales) of Hindustani music. It is also a specific raga in Khamaj thaat.

Khamaj Thaat

The parent-scale Khamaj Thaat, notated in sargam notation, has the following structure:S R G m P D n S'.In Western terms, assuming the tonic (Sa) to be at C, the scale would be:C D E F G A B-flat C.Khamaj thaat is thus equivalent to the mixolydian mode in Western music.

The Carnatic music equivalent of the Khamaj Thaat is "Harikambhoji", the 28^th Melakarta raga.

Raga Khamaj

Raga Khamaj, the specific improvisational scale based on this mode, has the following structure:

Aroha (ascending structure)-'N S G m P D N S'. If Sa=C, then this would translate to B C E F G A B C

Avroha-S' n D P m P D G m R S. If Sa=C, then this would translate as C B-flat A G F G A E F D C.

The vadi or sonant note is Ga, the dominant.The samavadi or con-sonant note is Ni, the mediant.There is no universally-accepted pakad for Raga Khamaj, although the phrase m-P-D-G-m-R-S is considered important. ND MPD MG too is quite predominant pakad.The prahar (prescribed performance time) of Raga Khamaj is 9 pm to midnight.

Hindi Film Songs based on Raga Khamaj :

O sajna, barkha bahara ayi - Parakh
Bada natkhat hai...ka kare yashoda maiya - Amar Prem
Ayo kahanse ghanashyam - Buddha Mil Gaya
Vo na aenge palatkar - Devdaas
A dilse dil mila le - Navrang
Dhal chuki shame Gam - Kohinoor
Khat likha de savariyake nam babu
Mere to giridharagopala - Meera
Tere bina sajna lage na jiya hamar - Aarti
Kuch to log kahenge - Amar Prem
Tere mere milan ki raina.

The Narsinh Bhajan "Vaishnav jan to" is also based on Khamaj.
