Jim Harvey is correct about making sure no one is in the line of fire in case a bass string breaks and becomes a projectile. Jeff Olson doubts that a broken bass string will fly out of the piano. Jeff, many years ago I doubted that a person could bang on a piano key hard enough and long enough to break a steel string, but I learned better. Since then, I have replaced a bunch of them, and it's the same scenario every time. I can predict when and where it's going to happen. I have also had broken bass strings fly. On one occasion, I was tuning an old Steinway L in a fairly large church. The piano was all the way over on one side of the sanctuary. A bass string broke, flew out of the piano, over a bunch of pews, and hit the wall on the opposite side of the sanctuary. "BANG-swish-SLAM!!. Just like that. Fortunately, it hit the wall, and not one of the stained glass windows. On another occasion during a revival at a rural church, a bass string of a small imported grand broke, flew half the length of the sanctuary, and hit the end of a pew next to the center Aisle. It can and does happen. I never let anyone stand or sit behind a grand piano when I'm tuning it. Jim Ellis
