Modulation Z is a winter drumline group consisting of students from Fort Zumwalt North, South and East high schools. It is the first and only combined competitive performance group in the district. Started in 2010, Modulation Z was created for those students who did not have a winter program at their “home” schools as a means for them to participate in this fun and exciting experience. It was originally conceived to be a one time thing or something that would occur every so often. But, due to the overwhelming positive results and feedback from both students and parents, it was apparent that “Mod Z” should take place every year.
