I have tried standing inside a church organ on a tour of it with the operator of said contraption hit a chord involving also pedal notes. Not an instant emergency , but certainly something that should not be unduly postponed, kinda metformin style. They btw. also got bridge-damage by troups wrong, it is much more likely to be about the repeated shockwave rattling a stonebridge apart than about resonance, a non mortared stonebridge is not likely to exhibit that anyway and those were the standard bridges the romans built. > george Peter Larsen |
