I was a classically trained Oboist as a child and I had some excellent teachers, but they only taught me to play and sight read pieces with technical perfection. Needless to say this was not fun and so I quit halfway through highschool. I ended up picking up the electric bass a couple years later and enjoyed it because there were no expectations and I could just learn and play on my own. As a kid lessons can just feel like a chore/school.
That is a serious flaw in how music is taught. Or maybe all the educators are right and I am off-base, but I had the same issue.
By Jr year in high school I was a pretty good trumpet player, and thought I was hot shit (dont all trumpet players though). Then I took music theory as an elective and realized that kids who noodle on guitar and only perform at the talent show had a better grasp on how music works and ability to create than I had despite being in a formal music program for years and having a private tutor etc.
Part of it I think is that wind instruments can only play one note at a time and classical music is on sheet music anyways, so keys end up just being a modifier that you keep in mind and chords are something that the other sections of the band do rather than just you. But I still wonder why even the fundamentals of how music works was not covered beyond what you need to know to read and count standard notation.
Some introductory piano was required for music theory and by the end of the class I could jam with great mediocrity but classical trumpet playing was never fun for me again after that.
