From an 8-dancer formation (a 2 x 4 for Stretched Box; a 1 x 8 for Stretched Column | Line | Wave).

Viewing the formation along its long axis, group the dancers into pairs (two adjacent dancers). Each center pair works with the furthest outside pair to do the given call, ending such that the 4 dancers are entirely on that far side.

Stretched Box:     Work with these dancers but...   do the call as if you started here.

Stretched Column | Line | Wave:     Work with these dancers but...   do the call as if you started here.

• The given call must be able to be done by 4 (or fewer) dancers. The call can not be an 8-dancer call.
  • For example, from a Double Pass Thru formation, Stretched Box Rotary Spin is illegal because dancers within one group of 4 would be required to work with dancers within the other group of 4. Similarly, from a Tidal Wave, Stretched Wave Relay The Shadow is illegal.
  • Stretched Box | Column | Line | Wave identifies a formation (i.e., a Box, a Column, a Line, a Wave) of 4 dancers that has been 'pulled' or 'stretched' apart; dancers do the given call while simultaneously pulling the 2 portions of the formation together.
  • The words Stretched Box | Column | Line | Wave by itself is not a call, and does not mean to move anywhere or to do anything.
• If the given call can be done by either 4 or 8 dancers, do the 4-dancer version of the call. For example, on a Stretched Box Counter Rotate 1/4, the Counter Rotate would be a Split Counter Rotate. A Stretched Box Circulate would be a Split Circulate.
• The Outside pairs of dancers do the call 'normally' (i.e., as if they were working on their own side).
• The Stretched Box | Column | Line | Wave CONCEPT [C2] is different from the Stretch CONCEPT [C1]. Listen for the word 'Box', 'Column', 'Line', or 'Wave.'

• Some dancers immediately do a Centers 'Substitute' (or Centers Half Sashay into the other Center position) and then do the call on each side. Although this may help dancers to visualize and execute the call, it is almost always awkward to dance. Please try to avoid doing this! Instead, think about starting the call Disconnected and gradually blending such that the 4 dancers end together on the same side.
• From Columns consider a Stretched Box Peel & Trail: the awkward way to dance this would be Centers Substitute (Stable Zoom) and all Peel & Trail; the smooth way would be Lead two dancers Phantom Run and Press Ahead as Trailing two dancers Press Ahead and Trade.
• From a Tidal Wave consider a Stretched Wave Explode The Wave: the awkward way to dance this would be Center 4 Once Removed Half Sashay (yecch!) and all Explode The Wave; the smooth way would be Step Thru; Face In; Centers Pass Thru; all Right Pull By.
