My pet theory (which complements yours) is that it was, before the invention of writing, part of the mnemonic techniques used to perpetuate vital information. Other worthy mentions are story-telling/acting, poetry (rhyme and meter) and painting.
Being innately predisposed to like these disciplines makes one more likely to practice them, become good at them, and help propagate useful info undamaged, thus rising the group's survival abilities.
They were vital for so long (compared to the few millennia since we invented writing) that we still have the taste baked in, even though writing, then the press then computers and photographs took over those roles.
Rhymes and meter are the CRC32 check of prehistory.
- jvanderbot 7y agoI was hoping to add an original thought to this thread, but you nailed 80% of my point. The remaining 20% is that music allows "chunking"[1] complex knowledge into a single song that's easy to remember. 1. https://en.wikipedia.org/wiki/Chunking_(psychology) https://en.wikipedia.org/wiki/Chunking_(psychology)
- nitwit005 7y agoI wouldn't assume it's a positive trait. People take pleasure out of things like optical illusions, which are arguably defects in human vision. There is a 3-5% rate of people who don't enjoy music, and it at least doesn't obviously handicap them: https://en.m.wikipedia.org/wiki/Musical_anhedonia https://en.m.wikipedia.org/wiki/Musical_anhedonia
- andykx 7y agoAre people really pleasured by optical illusions, or are they interested by them? I think that most people understand that their brains are struggling to comprehend them, and that is why they are interesting. Regardless, I don't think there's much evidence (if any) for the idea that the enjoyment of music is the result of a defect in our auditory system.
- nitwit005 7y agoPeople certainly enjoy magic eye books and the like. Defect would imply it's a negative trait. A lot of mental quirks are probably just irrelevant from an evolutionary point of view.
- Digit-Al 7y agoI would argue that magic eye books and optical illusions are different things. An optical illusion exploits our brains "shortcut" mechanisms, which could be considered taking advantage of a weakness, whilst a magic eye utilises our pattern matching ability, which could be considered as bolstering a strength. Not sure I've explained myself as well as I could, but hopefully I have.
- nitwit005 7y agoEvery optical illusion is some good aspect of vision failing in a limited case. Evolution is presumably selecting for the good aspect, and not the occasional hallucination it produces.
- pygy_ 7y agoIt doesn't handicap them today. I think it would have handicapped them 4000 years ago. There is actual evidence for my theory BTW. Aboriginal folks in Australia had a tradition of using songs to describe itineraries. Antique poetry and the bits of oral traditions that survived until today were using heavily structured verses (like the dactylic hexameter). A notable exception is the old testament, whose first parts were transmitted orally before being written down, and which is structured in verses of unknown structure (or unstructured, except for the psalms). Modern poetry has gradually lost that strong structure. The prevalence of musical anhedonia and amusia may very well have risen in recent times as a result of the loss of utility of music. ———— https://en.wikipedia.org/wiki/Amusia https://en.wikipedia.org/wiki/Amusia
- nitwit005 7y agoPossibly, but it'd be a fairly minor handicap. Remember that people who don't enjoy music have no problem learning music or instruments, and plenty do. There's no obvious way it would result in your death. We tend to make the mistake of assuming any seeming oddities of the human must somehow be due to evolution. But when we see the same in the rest of the body we often make the opposite assumption and assume it's a vestigial trait, or a coincidence.
- pygy_ 7y agoMy point is that taste in music is vestigial since the invention of writing. Before that it was a selective advantage. Even if amusia (of which musical anhedonia is a subtype) was prevalent at the time, culture transmission operates at the group level. The mere existance of amusia with such a low prevalence doesn't invalidate my point.
- irrational 7y agoAnd thank goodness. I have musical anhedonia (https://en.wikipedia.org/wiki/Musical_anhedonia https://en.wikipedia.org/wiki/Musical_anhedonia), which basically means that music does nothing for me. I function just fine in today's society, where music is merely entertainment. I probably would've been screwed if I had been born thousands of years ago.
- naniwaduni 7y agorhymes are very not universal
- pygy_ 7y agoTIL. Verse structure appears to have been widespread though.
- j7ake 7y agoEven after the invention of writing, music and art is still a vital medium through which to perpetuate vital information. Not all ideas can be distilled easily into words.
- pygy_ 7y agoPerpetuating it is not vital anymore. The civilization could most likely survive the abrupt loss of every piece of music poetry and painting ever created up to this point.
