If high school music department bands count-i did a lot. First semester was generally my busiest time of year i did: Wind Band [concert band], Jazz Band, Marching Band, Show Band [pep band], First Edition band [show choir], and was in an outside of school jazz combo. So that would be: 6 all going on at once in addition to at the time-school, work, and private lessons. However, show band and First Edition band did not start up until after marching band was over.
2nd semester: First Edition Band, Wind Ensemble [#1 concert band], Jazz Band, X-Cap Band [#2 & #3 show choir band], a praise band, and every so often an outside of school combo or rock band.
If school related bands don't count-i did a jazz combo,a praise band, and a rock band.
Now? I've got squat since i'm in the summer between high school and college. I'm playing with the Purdue University Summer Jazz Band, a praise band, am in the process of starting a combo, and besides that-it's all solo stuff-in other words me practicing outside on rare occasion.
I'm excited about college [jazz major] since there's a lot of playing and practicing involved.
That's all
