I'm having trouble pronouncing some gurmukhi letters, I have jus started going to santhiya about 3 weeks ago but I'm practising at home bit still getting it wrong. I'm fine on most of them apart from the last 1 which is rara , I was told it sounds like a d in English but I can't seem to do it, also I struggle on differing the sound between tutta and thutta , can somebody please tell me how you pronounce it, where do you place your tongue when saying it, behind teeth, top of mouth etc. thank you
