Pitch or intonation?

Question
Can you explain the difference between "pitch" and "intonation" in terms of how VCAA uses them? Because as I was taught, 'intonation' is changes in pitch, whereas pitch relates to how high or low something sounds. But VCAA uses transcript symbols which indicate 'rising pitch' and 'falling pitch' (which sound like changes in pitch, which relate more to the definition of intonation!), and 'continuing intonation', 'final intonation', and 'questioning intonation', which I'm not sure what these exactly mean.

Kate's response
That’s a really good question Jen — those terms often get confused (referring for example to the general the highness and lowness of voice). Here are the short definitions we’ve given in the glossary for the Lingo books, and they fit the account you’ve given here:
 
Intonation is the way pitch changes across an utterance. See also intonation contour.
Intonation contour is a distinctive sequence of pitches in an utterance.
Pitch relates to how high the voice is, reflecting how quickly the vocal cords vibrate.
 
So pitch refers, as you’ve described, to the highness and lowness of tone or voice, and intonation is the distinctive use of pitch patterns in speech (sometimes called melody).
 
Intonation reflects a speech style that’s appropriate to the utterance and the context; for instance, the degree of formality and/or authority. The following example shows a pitch trace (in blue), and you can see that there is an utterance-final “high rising terminal/tune/tone (or HRT)” in the sentence The mentally ill man who burnt down the St Kilda kiosk last year’s been jailed for three years. It’s a speech style that is more likely to resonate with a younger age group (this sentence was read by a female newsreader on a mainstream Melbourne FM radio station — and many thanks to Jenny Price for this example).











The various labels this distinctive intonation goes by underscore the confusing terminology here: rising inflection, upspeak, uptalk, high rising intonation, Australian questioning intonation. (And of course HRT is confusing enough!)
