Fair enough. But I'm not sure that it's as intuitive to equate higher pitch=3D greater q= uantity. I mean, I can grasp it visually (I suppose one could try for an ev= olutionary argument - a higher pile=3D a greater quantity, or some such). Also, in your example of larger data values represented with increased heig= ht; yes, but "larger" in this context means "relative to other data values = currently presented" - a bargraph is good for that kind of simultaneous pre= sentation. I'm not sure how well this translates to the simultaneous sonifi= ed presentation of comparative data? I could see how the graph could be presented non-simultaneously - scrolling= left to right, we hear pitch rise and fall. So in this case, comparative d= ata has been translated to pitch change direction - over time. In respect of your question, I have a hunch that there is a learning effect= here, and people who (for instance) have often worked with visual represen= tations of sound (as in DAWs) will readily grasp the "more=3Dhigher" concep= t, than others (even musicians-but-without-production expertise).
