I started experimenting with some altered tuning for a potential music project / sound installation at the Shatford Centre. I am de-tuning an old upright piano approximately a 5th lower than your average piano which creates a very different timbre, closer to a steel drum than a piano. Just down the hall from my shop space there is a terrific stairwell which has wild reverb going on. I found the resonant frequency of the stairwell (201.37 Hz) and am tuning the piano to a just intonation scale based on that frequency. Once I have stabilized the tuning of the piano I will roll it into the stairwell and see what it sounds like. I am imagining a multitude of harmonics being activated, but who knows if it will work. I will keep you posted.
