i replied to any other post and mentioned keen, and thought about it.

i can't keen unless i am truly heartbroken, if i try to do it otherwise, i fail-- but i continue, i can eventual keen, but when i hear the sound of keening, (and when i keen) i feel sad--hearing (and making the sound) effects my mood.

i remember seeing a Nova (a PBS science show) some 15 or more years ago, and it pointed out that certain sounds invoke emotional responces. (there were several studies done on it... ) cultures all over the world use certain tones, with certain lenghts, to invoke emotional responces.. Beethovens 5th, (Ba da da dumm) almost everywhere invoke gloom, terror, foreboding.. everyone hears doom approaching. other sounds, joy, others, reverence

just like Yawning is "contagious"-- some sounds are too, and the sounds can serve to change an emotional response...

i don't think the world giggle is likely to cause others to giggle, but one person giggling can soon have a whole room in gleeful mood.

in keeping with words for sounds, are there any words that sound (or evoke an emotional responce) how they feel?
--Whoops are another sound that carries an emtional responce, one of pleasure and excitement. i don't think i could whoop unless i was really charged up and happy. but the word whoop itself is flat
