About Arc It Up
Arc It Up is a free web tool for ensemble directors looking to quickly produce clean, professional-looking seating charts for their ensembles. Useful for musicians locating their seat, stage crews setting stands and chairs, and directors who need a reliable way to figure out where everyone should be in the arc.
Designed by John Mange, D.M.A. student in wind conducting at the University of Michigan. Built with Claude Code. No user data (besides anonymous, aggregate web traffic data) is collected here; charts you build are only visible to you.
Thank you to all of the people whose input and suggestions went into the design of Arc It Up! I hope it saves you and your ensemble members a bit more precious time, so you can focus slightly less on logistics and slightly more on artistry.
