Hey Trompetvrouw
Great topic! I may be an oddity but this is how my training went. My Aunt
was a world class pianist working with the Toronto symphony till her death in 1998.
She always tried to get me into piano but the instrument just didnt speak to me. Then I saw Miles in concert in 1990 and that was it for me. I was dirt poor in those days but scraped enough money together to get a beat up old Conn trumpet. I couldnt afford any lessons from a trumpet player so I got the Harry James method, Arban's and a 'learn the trumpet' video and began to teach myself.
I took to the trumpet so fast that it wasnt funny! My aunt got wind of what I was doing and took me under her wing and taught me 5 or 6 years worth of Jazz and Classical training from a pianists perspective. She told me almost from day 1 that my ear was exquisit and I was absorbing everything on the trumpet like a sponge. She wanted to pay to get me lessons with a trumpet teacher but I was doing so well that we decided not to go that route. She was an incredible wealth of theorie. Everything else I took care of myself. So I have theorie training from a world class pianist but the technical stuff on the horn I am completly self taught. I guess I did ok cause I always get tons of compliments on any pro gig I play.
Hey dnlrsnbm
Your friend Vinny sounds a lot like my aunt. She was not only an incredible pianist, but also a great guitarist, violinist, floutist and harmonica player. We used to do stuff like that all the time, she would teach me advanced theorie and then we'd jam and improvise to the point that I couldnt play anymore that day. And we did this for years

Sweet memories!
