Sure, there is •something• to that. But my love is solo piano music, and the primary way that repertoire has led to social connections throughout history is from people playing in the home or for small groups of friends — and also from learning and teaching it.
I see those same impulses at work in people sharing DAW tips and tricks with each other, getting together to listen to works in progress (which very much happens), etc. The instinct is there. The possibility is there. It’s social support structures — time and slack, first and foremost — that are missing.
There are always avenues for turning a completely solitary creation into a point of human connection in a well-functioning society.
