Being a musician, in whatever form it takes in your life, is part and parcel of who you are and the air you breathe. It is therefore part the reason you are (or aren't) attractive to someone so why wouldn't you support it? It isn't my partners thing but he totally gets it and it's a quid pro quo in that I support the things that are important to him.
When I met my fiance, we had only known each other for one month. We were sitting by the pool in Hollywood, and I asked her what she thinks we have in common. She said,
"Nothing." I replied,
"Cool."
But her Mummy corrected her, letting her know that she loves music, and I make music, so we go together.
We later went to a yard sale, where I saw an old Korg DDD-1 drum machine. I told her how I had one of those, when it was new, and it was super expensive, and it had gotten stolen. She bought it behind my back and surprised me with it.
That was 18.5 years ago. Since then, we've been on lots of music adventures. She learned how to string and tune a guitar or bass, yet can't even play. She learned how to set up and tear down a six-piece drum set. She even found that she had a preference with certain types of music gear, and would go buying cymbals all the time, based on sound, bell, etc.
Over the past few years, she's been buying guitars. She bought my PRS, and it was the kind of thing that bordered on an impulse buy. That was after I played it and said that I
really, really like it.
She said that the PRS is hers, so if we ever split, she gets it. That's a double-whammy that I don't even think about. But yea, that guitar is hers. I just play it. Sounds fair, and that speaks to the quality of our relationship.
Things are reciprocal, of course. I stand quietly at Michael's while she buys a truckload of yarn for the storage unit. Still waiting on her to knit me one of these. Someday...
