<HTML>List, I would not hesitate to bring it up to pitch,the piano is designed to work and play at that pitch,with that tension.It can change bad singing dampers when the tension is correct,as well as other problems.Also if you turn off the tuners ear when finished,and turn on the musicians ear,which is so important, it's all the difference in the world.I use liquid wrench,dabbed on termination points,with a small brush.It will really reduce string breakage,on old strings.
