Unique "Murchana" Record

In Hindustani music, "Murchana" means shifting the Shadja to obtain a different Raga. Ustad Imrat Khan, the Surbahar & Sitar Maestro, has recorded an unique LP where he has used this technique to use his two different instruments to play two different ragas so that they sound like a continuation rather than two different ragas.

Raga Abhogi is played on Surbahar, which is tuned a fourth lower than the Sitar. The notes used are S R g M D S, the semitonal intervals between the notes being 2,1,2,4,3. This is followed by Raga Kalavati played on Sitar, the semitonal intervals between notes being 4,3,2,1,2. If the Madhyam of Abhogi is used as the Shadja, one may obtain the notes of Kalavati. Conversely, if the Pancham of Kalavati is used as Shadja, the notes of Abhogi may be obtained.

"Jasrangi" developed by Pandit Jasraj also uses the same technique but in Jugalbandi between male & female vocalists, whose natural Shadja is half an octave apart. So they can sing two different ragas at the same time, sounding as if they are in unison! The man may be intoning Pancham, which may be the Shadja for the woman (in another Raga, the intervals of which should be the same as the different Raga being sung by the man!)

In the extant YouTube video, Dr. Ashwini Bhide Deshpande is singing Abhogi whereas Pandit Sanjeev Abhyankar is singing Kalavati in unison!
