I think I've tabbed mahaganapathim without any open notes, so it can easily be transposed to any key u want.. just move ahead/back right no. of frets (or detune )
I will post the rest of mahaganapathim soon.. been a little busy.
You can get the notes corresponding to sa re ga ma for a particular raaga for a song and use that to play it (from the sa re ga ma notation)
for instance, nattai is a janya of chalanatta for which the notes correspond as:
S R` G M P D` N S
C D# E F G A# B C
But the gamakams are important and change the way it sounds. There are lots of songs in this forum in this notation already and I'm sure more will come.
