Someone has finally come up with an easily retunable piano. Looks (and sounds) a little more like a clavichord, actually, and while I’m pleased about the retuning, each string appears to have only about a whole tone’s leeway. You’re still more or less limited to 12 pitches to the octave, but there’s a lot you can do with that: not only meantone and other historical temperaments, but the tunings of most of the standard pieces for retuned piano: Ben Johnston’s Suite for Microtonal Piano, The Well-Tuned Piano, The Harp of New Albion, and so on. It’s presumably far more affordable than the piano Trimpin once designed for me on a napkin, which could be automatically retuned via computer while you played. They’ll have a whole world of microtonal acoustic instruments invented by the time I’m too old to lift a pen to write for them. (h/t to McLaren)
