Mack, I read your post and said "What the... That doesn't make any sense!" When people are talking technical talk, that feeling's usually an indication that I could learn something.

Tone, as per McGrath's quote from Oxford, #5, means the note. Pitch would be the frequency. I'm trying to think this through, and wonder if 'tone' doesn't have something to do with how we perceive sound, and other things besides pitch determine that. Sometimes, when a specific pitch gets louder or softer, I hear it as sharper or flatter. The volume doesn't affect frequency, but it effects how I perceive what I hear.

The Doppler Effect definitely changes tone, but it's because the pitch/frequency also changes at the place where the hearer's located even if it doesn't change at the source.

I'm thinking there must be re-prints of Analog around.
