Meaning that the author is maybe not very good at their craft, but inadvertently created a work with a lot more meaning than they intended, or they accidentally did something quite clever that they didn’t mean to. Or maybe a work which is good in its own right but there’s a particular “unofficial” interpretation which makes it so much better.
Obviously a bit of this question involves knowing authorial intentions, but in a lot of instances authors have been able to state that they did or didn’t intend a particular interpretation.
Well I play violin in a Celtic bar band that mostly does covers, but back around the time of the pandemic when I was feeling super bored, I worked on a song I’m kind of proud of? It’s called Anticipation.
I just casually mentioned to our lead singer that I had some licks that almost seem to be coming together like a song? He was similarly goofing around in his basement and said show me what you got? Next thing you know, I was trying to write parts for accordion and other instruments we had at the time using GarageBand on my iPad while he came up with some lyrics. I was a total amateur at this kind of thing and couldn’t believe it actually happened! But we eventually got it recorded with each band member coming in at different times for social distancing. We still play it once in a while at gigs when one of the regulars requests it.
