> Tonal language speakers (e.g. Mandarin) have absolute pitch with higher frequency

This is interesting, because a tonal language like Mandarin does not care about absolute pitch; it's all relative. For example, 1st tone is a (usually higher) flat tone. But it doesn't matter what pitch you use. 2nd tone is a rising tone, but it doesn't matter what pitch you start at or end at; it just matters that the two pitches differ enough that your listener can tell that there was a change, and that it was rising.

I wonder why that sort of thing also leads to a higher prevalence of absolute pitch.
