Hi Ron, You forgot the most important factor in pipe organ pitch. Barometric pressure determines the number of molecules of air that go thru the pipe. More molecules, higher pitch; fewer, lower. I measured a pipe organ where I was going to perform on a Friday evening. It was 20 cents flat. On Sunday it was 20 cents sharp.

The pitch was just >>above A-443. >Hi Greg, >The situation here is that pipe organs are tremendously unstable >instruments, with metal and wooden pipes responding at different rates, and >in different directions to temperature and humidity swings.
