This previous Shruti P1 has a frequency of 148.148 (if Shadja is taken as 100 Hz), and can be played on 67.56% length on the string. The scale starting from M1 is close to the current version of Khamaj (raga). Now, the notes at 3, 5, 9, 13, 16, 18, and 22 becomes the Madhyama Grama, these notes are separated by 3, 2, 4, 3, 4, 2, and 4 shrutis respectively. Musically, P in Shadja Grama (3/2) operates as the Perfect 5th, and the same shruti (P2 in Madhyama Grama) operates as 9/8 (another ratio for Just Major Second) in Madhyama Grama, because the Fundamental frequency has changed to M1.
