I remember seeing my first drum corp when I was 4. Yes, I remembered then at 4 years old because it was the Hawthorne Caballeros. Who wouldn't have remembered that?
Jump to elementary school. My mother made me take guitar lessons. That was the extend of my "formal" musical training.
Jump to high school where I was a member of our marching band's "drill team". Yes, I'm dating myself. Those were the days when the only flags carried on the field was by the girls who didn't learn their drill them drill well enough to perform that week. They stood with a 7 ft. wooden flag, just to mark points where the band should stop, turn, about face, or whatever.
Jump to college where I learned what a "real" color guard was, and re-discovered drum corps in Birmingham 1979. Was already too old to march corps, but been a fan ever since. Also worked with high school guards in my time. But that's the extent of my actual experience.
Does that mean I can't recognize good brass, good percussion, good visuals, good ensembles when I see/hear them? I sure hope not. Learned a LOT about music though drum corps without ever playing a marching instrument. Learned a lot from other fans, from band directors, and from a good friend way before he became a DCI judge.
Passed the love of the activity to my daughter, who played in marching band, did guard for one year under the direction of the aforementioned friend/DCI judge, and worked with a guard of her own in college. She had way more musical experience than I did and I learned a lot about music from her too. She had many good friends in Carolina Crown, and would have loved to march with them, had she been able.
I've turned my husband into a pseudo-fan too. If you ever see a guy in the stands reading a book, that's him. He's not as into it as the rest of us, but he loves to listen to the music while he reads, and can certainly tell when someone has hit a less-than-perfect note (he says he has to read that page over again).
So I guess this qualifies me as on of those "other" fans?
