''"Most people have experienced this phenomonon when watching newscasts with a satellite uplink or speaking on a cell phone -- there is a perceivable difference in time between the moment someone speaks and the apparent time the other party hears them... The end result is if two people are trying to play a song together, the induced lag (which is termed latency by most tech heads), ends up causing each person to extend their tempo waiting to catch the other person’s playing. Since the other person is doing the exact same thing, the end result with two people is usually a continually slowing tempo."''
