Greetings, << I don't know the accuracy of this theory, or if there is a planet that takes 432 days to orbit the sun. My thought when I heard the theory was, to quote you, "Yeah Right!">> It is interesting to hear pianos at much lower pitches than are common today. When chipping a newly strung piano, I will do the first tuning at a low pitch, just to aid in moving strings, beckets, etc. It is at this time I usually try one of Owen's temperaments, doing a little sketch work before I pull the piano all the way up. It is not uncommon to find the smaller grands having a real nice tone at something like A-430, losing it out to more power, (albeit strident power.) as i bring it up to 440. Several of my instruments exhibit this trait. I have a Hurdy gurdy that just sings in Bb, sounds sedated in A, begins to get right peppy in C, and squawks when pulled up to D. Some pianos just may be a lot nicer sounding when tuned low, and the singers sure are going to run out of range if the present practise of increasing pitch continues. Ah well, There is a religious movement associated with the 432 reasoning, but there are acoustic reasons for a lower pitch, as well. Regards, Ed Foote
