If I really need to do a sonogram, I use the one in CoolEdit/Audition. If I
just need to know a pitch, though, I reach over and grab my Baby Taylor
guitar.

Having spent alot of time looking at realtime FFT spectra for various
musical instruments, I can attest that it can be difficult to discern the
fundamental frequency using this approach. This is a consequence of many
factors, including how much harmonic content there is in a particular
musical instrument relative to fundamental content. Additionally, the
sampling chain is important as well. However, it should be possible using a
realtime FFT analyzer, many of which are available as freeware downloads for
PC and Mac. I think the advantage of a realtime analyzer vs. built-in
software in SF is that you can actually see each band "moving" and get a
sense of where the fundamental might lie. It'll take some practice, but it
should be doable.
