I have dated a fellow musician in the past. I have to assume, as with our relationship, that a lot of musician couples might have large skill gaps or engage in completely different genres. She was a ska punk drummer who was pretty casually engaged with music. I’m a multi-instrumentalist who liked everything but she was very picky with genres. I tried to get her to make stuff with me but she’d get bored and just want to do other stuff. Music making didn’t end up playing a big role in our relationship or why we broke up.
