How to speak Spanish.

I've noticed something recently: that intonation and rhythm are almost as important as getting the individual phonemes right. That is, you can get all the individual sounds correct yet still sound horrible. There is a basic, simple rule for Spanish intonation. Start at a low pitch, when you get to the first accented syllable of the phrase, go to higher pitch, and MAINTAIN THIS PITCH until the final accented syllable of the phrase, then drop down again for remaining unaccented syllables. (Or raise the voice to an even high pitch for yes-no question.)
