I've recently been taking a break from raga yaman and have been tinkering with raga bhimpalasi. I will post a video at the end of the post to give you an idea what this raga sounds like.
However, first I want to list some tunings for various ragas. Tunings for ragas can vary quite a lot depending on which school/style that you follow so the following tunings are just guidelines and changes can certainly be made. I will start with the main playing string (Ma) and work down towards the high pitched strings. You may need to adapt them for your sitar, I use a Gandhar Pancham so it may be different to yours.
(these ragamala paintings don't all correspond to the raga listed)
