Hi all,How is harmonics generated? Why are they integral multiple of thefundamental frequency?Thanks

When I first read that name, I sounded it out, and it came out (in my head) as "YO-se-mite." I had a 5th grade teacher who pronounced it that way, which kind of reinforced that. I never made the connection to "Yo

-SEM-i-tee" as in "Yosemite Sam", until I heard some TeeVee nooz story on the town, or whatever it is. Or something. I was astonished. :-)

Then again, I had grown up in Minnesota, where, it seems they have an accent of their own.

I was talking to a sales rep not too long ago, and while we were making small talk, he asked, "Can I ask you a possibly personal question?" I said, "Sure, if I don't like it I just won't answer it. :-)" He asked, "Are you from Minnesota?" "Yeah, did you spot my accent?" He said yeah, but he was from there too. :-)

Tooele, Utah, too. :-) It's pronounced "too-EL-la", but even the people who live there (well, mostly on the army base nearby), talk about being "in the Toolies". :-)

Cheers! Rich

I grew up in Vermont about 50 miles south of the town of Barre - pronounced "BA-ree". When city folks would ask for directions to "Bar" we rustics would gleefully direct them to the nearest saloon. Then there was the nearby town of Contoocook New Hampshire, pronounced "con -TOO- cut". go figure.

Well, just exactly as it's written:

;-)

Bei3 (sinking then rising tone) jing (high constant tone).

This is very flat (from an English dictionary) but has the right idea:

Here is the word in a sentence ('Ich bin ein Beijinger') with proper pronunciation:

Literally, "I am Beijing person".

;-) Independent university town bookstore, run by a colorful (possibly gay) pair? What are the chances of that?

Four or five in Mandarin, if you count the neutral tone. More in other dialects. There are too few monosyllable sounds for too many words, so it's necessary to do some disambiguation by other means.

Beijingers seem to like to roll their R's more than others when speaking Mandarin.

And here I thought you were a believer in basic physics... :-).

It's also done on guitars and other stringed instruments. For all I know, there may be analogous physical phenomena in woodwind, etc, but even if not, the players of those instruments tune using embouchure and their ears, so they will naturally stretch their tunings to match.

There's much more energy in the harmonics of stringed instruments than there is in the fundamentals, so matching them is important.

I don't think the brain really gives a rats about exact octaves. It's the fact that when you play two strings whose fundamentals are at exact octaves, the harmonics beat, and the higher harmonics beat faster. The (faster) beating harmonics can be more annoying than a slow beat in the fundamentals. It's really a matter of taste, and of which harmonic frequency range your ear is more attuned to.
