For starters get her into a good choir.

Maybe try the reverse. Get her to speak a paragraph of text in strict metronomic monotone, and contrast with the same in normal speech. The value in speech inflections is too often overlooked because it is a normal part of what we do every day. Ask her to think of punctuation, if she were to insert such devices into music what would it sound like. Sing, sing in a choir, listen to vocal music, etc. Can not be emphasized enough.
