OK, I'll go first.
I played cornet for three years in Jr. High school. Was fairly good, third or second chair first section. One guy and I kept switching places with challenges. The music teacher said I would have been first chair but the first valve on my horn kept sticking, which was a real pain. Annoyed the heck out of all the boys in the class that were behind me.
Of course, there was only one other girl in the class, she had 5 years of private lessons and was first chair - story of my life. Worked so hard to succeed when others got the breaks, but circumstances blocked the first chair. The best I could get was second chair.
But, I actually practiced just about every day trying to get better and overcome that danged sticky valve, and loved playing. So maybe that was for the best.
I may have become very annoying if I had been the best trumpeter in that 100+ band with about 25 cornet players.
Ahh, who am I kidding, we were all band geeks. No one cared what we were doing.
There's a synergy to music when played or sung with others that you don't get in many other places in life. It can be very visceral. I found it to be almost intimate, even when performing in front of a crowd. It touches a part of the mind that it seems nothing else does. Magical, it is.
In high school I switched to chorus because I didn't want to do the marching, and heard the band teacher was a real... SOB. Actually, I enjoyed chorus pretty well too, except the teacher kept trying to get me to sing alto when I was actually a 1st tenor. I know, girls aren't supposed to be tenors, but alto was just too high for me.
We sang in band too, before playing our instruments, so we could figure out what it was supposed to sound like.
Can read the treble clef in written music - Every good boy deserves favor. Grew up with classical because my mother listened to it all the time. Of course, went with rock as a teen in the 60's, but still loved classical (Bach, Beethoven, Mozart, and so on), jazz, blues... pretty much anything but country. Well, some country, that is. I like Willie and a few others.
Don't know a lot about chords, a little about keys, and mostly just listen to it without much analyzing. But, am very willing to learn. Max and I have talked about getting a keyboard to mess around with some.
That sounds very interesting about the tonalities. I love minor keys, they often sound so plaintive. Chinese music has it's own flavor to it. There has been a show on Link TV (I think) called Music of the World that features lots of different styles and flavors that we have been listening to lately. It is astonishing the variety humans can come up with.
