Percussive Musical Array

Marching bands involve simultaneously practicing music and movements. However, the type and size of instruments are limited by their portability. Why not leave the instruments on the ground, and let performers move freely?

An array or grouping of percussive instruments could be set up where a marching band would normally perform, like a halftime show or special event. The performance would involve performers freely walking through the array holding strikers, hitting instruments as they pass by them. Each performer would be trained on more than one instrument, adding complexity to the performance. Both the notes and walking paths are choreographed and practiced like a marching band, but the heavy load would be relieved.
