Originally a 3 movement composition for electronic tape and three non-dancers/readers by Stan Gibb. October 1971.
The non-dancers performed on a dark stage with a flashlight in each hand (6 lights). The movement of the flashlights were choreographed by the composer.
This is a performance of the first movement which was programmed in 2008, using Adobe Flash software.
Have you ever watched a video of someone speaking in which the movement of the speakers lips were not in sync with the sound of the words? This is very frustrating, even distracting.
If and when the words and lip movement were corrected and synchronized, there was a sense of relief, relaxation, as though a goal had been reached and you could then focus on what was being said.
This experience was partial motivation for Flash.
Flash utilizes, on the one extreme:
1) Image movments in which sounds are tightly synchronized.
And on the other extreme,
2) Image movements & sounds that appear to be independent of each other.
And several reltionships that are between these two extremes.
Folowwing is a list of levels of synchronization that lie between these two extremes.
1) Tight synchronization between visual movement and sound.
2) Leader/follower events: Events that are imitative and overlap.
3) Echo effect: Aural event that is imitative of a previous visual event and vise-versa.
4) Solo events: Visual or sounds that occur without visual or sound events.
5) Visual and sound events that occur without any imitation.
