I asked ChatGPT (3.5 turbo) for some examples of 双关语 = "puns". Among its examples is:
为什么音乐家总是迟到?因为他们总是在调音!
Why are musicians always late? Because they're always tuning. [my translation]
I asked ChatGPT to explain the joke, and it said:
第三个笑话是一个双关语,利用了“调音”的多义性。在音乐领域,“调音”(tune)是指调整乐器的音高和音色,以使其与其他乐器和谐地演奏。而在日常生活中,“调音”也可以指“调整时间”,让钟表保持准确。因此,这个笑话的双关语是指音乐家总是在调整乐器的音高和音色,而非调整他们的时间,导致他们经常迟到。这种反差让人感到出人意料和有趣,是双关语的常见特点。
I understand 调音 literally means "to tune" (a musical instrument), but I don't get how 调音 relates to 调整时间 = "adjusting time". It should be a pun of some kind, so maybe there's a Chinese word which sounds like 调音 and has a relevant meaning.
It's also possible this pun makes no sense at all.
Question: How do I understand ChatGPT's joke?
