advanced classes are usually restricted to special workshops
John's original post uses the term "improver's" which is new to me in MJ
In Argentinian Tango there are more levels
absolute beginners
beginners
improvers
intimidates
advanced
admission to classes above improver's is often by invitation only

*somtimes, the first move is a variation of the first move
