We had a Marching Band Drill Writer/Visual Tech who would use this instruction when talking about “horns up”. He wasn’t from Boston, but used that type of accent. Here is what he was talking about:
“Wait LONGA” means don’t rush it. Don’t move early. Wait until the last possible moment.
“Move FASA”. Once you move, move fast….like two film windows….. one you’re down, the next you’re up…. with very fast movement.
“Hit HARDA”. Without losing any teeth, stop the movement as if it hit something.
