Editing Caller (dancing) (section)

==== Patter calls ====
''Patter calls'', also known as ''hash calls'', are based on a quick and fluid succession of spoken ("[[patter]]ed") or sing-song delivered calls, often to the accompaniment of an instrumental piece of music that it is not necessarily recognizable as a song.  Choreography may appear "on-the-fly" with calls randomly strung together, but it conforms to strict choreographic rules.  Most patter calling is improvised by the caller as the dancers are moving; if the tempo of the calling is done at a fast pace allowing the dancers to flow from one move to another without pauses, it may be called ''hot hash''.

The primary purpose of patter calls is to give dancers a challenge by surprising them with unexpected choreography.

Many callers are very well known for their ability to put calls together to create a unique, smooth-flowing dance.  Some callers are also known for the unusual and interesting formations they move the dancers through.
