I keep thinking about this post! I’ve been trying to get back into playing violin on and off, and it does a good job of describing why I’ve found that so hard. I stopped early on in your fourth stage, and my ear is way ahead of my ability to play anything it actually wants to listen to.
I guess once I join an orchestra I’ll enjoy that enough to get some momentum, but solo playing is pretty unrewarding right now.
Oozeware?
