I am kind of new to the violin (I've been learning for about three years now). When I went to the shop to get my strings changed, they asked me what shruthi I play in and gave me strings based on the shruthi. They've never done that before though. My new strings have a whole bunch of ridges on them. My old strings didn't have those. What are those ridges, and what strings do people generally use for their violins?
I can't wear any traditional clothes like kurtis, half saree, lehenga or anything of the sort. I have sensory processing disorder (unofficially diagnosed) and most things that touch my skin borderline hurt. A lot of things make my skin feel like it's burning and I feel more discomfort than the average person from a lot of things, especially humidity, seams on clothes among other things. That's a very vague description of my problems. There's a lot more but I'm not going to bother you with that.
The only clothes I can wear are made of a very specific fabric and there aren't a whole bunch of clothes I can wear. I usually wear really worn down clothes with huge holes that are barely holding together. I look like a joke in family events. I sing carnatic music and I've had to skip a few opportunities to sing on stage because the dress code was traditional and I couldn't wear anything traditional.
I need some medium length keerthana recommendations about Ganapathi, preferably by Tyagaraja or Shyama Sastri and in ragas that aren't heavy. No karaharapriya esque ragams (for example, no abheri, abhogi, bhairavi, keeravani etc. I'm not referring to janyams here, I'm just referring to ragas that resemble karaharapriya.).
