There are times I think the instrument is beyond what anyone can comprehend as an influence on society and culture. Or what I can comprehend. Postured stupid heavy statement but there it is.
Piano would be the other contender but the real weakness with piano is simply that the mechanics are automatic, the sound generating mechanics.
With a guitar the player is the mechanical actuation. The player has to make the sound.
Nuance is still very much a part of piano, but, piano v guitar, no contest, guitar is the more human.
So what of the other stringed instruments?
They didn’t do rock and roll.
Tough break but I sure am glad we have guitar.
Guitar, the opiate of the enlightened few.
I don’t think there is really anything here I disagree with. I still curse the day I chose piano over guitar.
