I’m trying to advise peggy on how to indicate tones. Here is what I said…
[quote]You need to be very purposeful about it until the tones come absolutely naturally.
One should be high and very level. As you move to indicate the tone stop for a moment, your hand should be up around your eyebrows. Then as you say the word move your hand exactly parallel to the floor.
Two should start low, around your hips and move diagonally up till you get about shoulder height,
Three should start quite low, dip and come up higher than it started.
Four should start high and drop forcefully.
In each case pause for a moment before you start indicating the tone and be sure that the gesture actually matches the voice.
The gesture you use to indicate each of the tones should look exactly the same each time. Your students should be able to say what tones you are indicating with the volume “off”. If they can’t do that you are not being clear and consistent enough.
It is surprising really how difficult this seems to be for native speakers of Chinese. I’d bet that most students of Chinese could read aloud and indicate the tones (if they could pronounce them) much more accurately than most native speakers. [/quote]
While that might be correct in spirit I’m not sure that it is exactly correct to the letter. Tones should be indicated clearly and consistently whenever anything is being “taught.” I’m sure of that. What I’m not precisely sure of is exactly “how” they should be indicated.
Definitely the very worst thing a teacher can do is make gestures that are indistinguishable from each other. That happens when the person trying to teach you isn’t focusing on the tone and kind of throws it in as an afterthought, or just isn’t clear that they need to be done distinctly.
Anyway it would be nice to get started on training the locals how to teach us properly and the place to start would be with a definitive answer on this from the “one” person who definitely knows…

Oh, and a poem…
