A Little Shubhap in Your BeBop?
Melakarta #45 - Shubhapantuvarali
Due to the process known as graha bedham, which changes the śruti, or tonic, of a scale (Melakarta) to a different note within that scale, Melas #36 and #45 have the same tonal makeup, with each containing the exact same interval relationships. Only the starting point is different in each case.
This is the same type of relationship found between, for example, the Major scale and any of its modes (Dorian, Phrygian, etc.) - same 7 scale tones; different tonic.
As with the other posts on the subject, the objective here is to investigate the usage of these Carnatic (South Indian) Melakartas (there are 72 in all), as one would treat any 7 note western scale - as a melodic improvisational tool.
