This is interesting to me because I don’t think my original violin teacher or anybody has ever communicated to me about ‘light touch’. I wonder if all the tension involved in clamping fingers on strings may contribute to back pain. Which I certainly suffer from! So this thread has inspired me to try touching the string really lightly so that when I bow I get a buzz, then continuing bowing while slowly increasing the pressure until I get a sweet tone. If I repeat this enough, I hope to get a feel for the actual pressure required.
