List, I am mystified at what happened yesterday to a piano that is tuned several times a year. Last tuned in May at A-440 I found the overall pitch to be 20 + cents sharp. Since this piano is not my favorite so an extreme solution came to my devilish mind. Using the string roller I proceeded to go over every steel string using generous force. This accomplished two things. 1. It made me feel better physically as I rolled back and forth on the strings. 2. It brought the pitch down close enough so that a one pass tuning was possible. Question: Why did this work? Where was all the 'slack' in the strings that put the pitch close to A-440? Anyone have this experience particularly at this time of year when the pitch is traditionally sharp? Will this work if I roll the tenor strings above the bass break where they are usually sharper than the rest of the piano after Summer humidity? Totally mystified in Madison.
