Connection is essential to all partner ancing. In Argentine Tango, Lindy Hop, Balboa, East Coast Swing, West Coast Swing, Salsa, Contra dance, Modern Jive and other styles of partner dance, connection is the primary means to communicate synchronized dance movement between the lead and follow. Other forms of communication, such as visual cues or spoken cues, are often considered to spoil the dance, unless used in specific circumstances, e.g., practicing figures, or figures which are purposely danced without physical connection. Connection can be used to transmit power and energy as well as information and signals - some dance forms (and some dancers) are at one extreme of pure power, and others will be at the other extreme of pure signalling, but most are probably a mixture of both.
