Visual Performance is more than just technique. It is technique and excellence on the field level. It covers form control, space, etc. This includes the color guard technique, timing, lower body, drill. It also accounts for written vocabulary and demand.
Visual Ensemble is half composition and half excellence.
Visual GE is how effective the program is visually and also includes the visual musicality of what is written. Music can affect the Visual GE caption. Performance is also a sub caption.
