I was also lucky enough to have the whole "actually rebellious" aspect, I think you are lucky if you get that, that's why so many kids of rockstars are absolutely fucking awful. I am from an extremely musical family, many of which are professional musicians, who were classical music snobs who considered electric instruments an abomination. I didn't know anything about any sort of music other than classical until I was 13. In 6th grade when middle school rolled around you had to enroll in either orchestra, choir, or band. I begged my parents/grandparents to enroll in orchestra playing the violin and they were like, "you have no innate musical talent and you don't have the discipline to stick with an instrument, you have to do choir". I got into non classical music when I was like 13 and started wanting to play an instrument even more then.
They actually never OK'd it. I kept asking for the next 3-4 years. They wouldn't even let me get a guitar with my own money. I had to order a bass in secret and arrange delivery when no one was home. Eventually I got tired of all the secrecy and wanted to practice amplified when others were home and spilled the beans. By then it was time to apply for colleges and I was like, "oh, and BTW, I also want to go to school for music to learn technical music theory".
Anyways, did all that. As anyone who actually knows music theory will tell you, there is no such thing as innate musicality. The locations of the notes in Western harmony were arbitrarily picked by humans and have changed over the centuries. As anyone who understands how guitar intonation works realizes, Tonality is just a bunch of workable approximations we consider acceptable that we have sublimated into the collective social subconscious through gestalt psychology. Anyone who tells you they have perfect pitch knows fuck all about how music actually works.
So due to the way I started playing instruments and an interest in the history of music theory and music in general, I don't actually consider anyone a musician or a "musical person". I never became a musician, I just got so into music I realized "musician" is a useless distinction. I think it's an elitist distinction that actually hampers creativity. When someone in this hemisphere of the world says they are a musician or were always a musical person or have a natural ear, all they mean is that they are proficient in following a system of rules that has existed since the middle ages. The rules are just negotiated approximations that were considered "close enough to be acceptable". I'm not a delusional enough to think of myself as a musician, but I think anyone doesn't know what concepts like equal temperament, just temperament, schismatic temperament, Pythagorean tuning,etc. are who won't shut the fuck up about their musical sensibilities is even more delusional.
Robert Fripp actually touches on a lot of those ideas in his excellent 1986 interview.
