Occasionally, as for instance in “Country Gardens,” the term “Half-chain” will be found.  This means that the movement shown in Fig. 4 is executed to four bars of music; another movement follows; then “Half-chain” again, bringing numbers back to original stations.

If, as very often occurs, the Chain follows a movement executed in Front formation, the dancers simply turn and follow one another as shown in diagrams, when the Chain music begins.

This is called in the Notation—­Chain.

CROSS-OVER.

This movement is executed in Front formation, to eight bars of music, as follows: 

In the first two bars each dancer crosses over and takes the place of his partner, setting the pairs back to back, thus: 

[Illustration:  Fig. 1.]

[Illustration:  Fig. 2.]

In crossing and re-crossing, invariably, each must keep his partner to the right, that is, the right shoulder of each passes by the right shoulder of each partner.

In bars 3 and 4 (keeping up the step all the time) all come to the right-about, that is, face inward again, by turning to the rightward (maintaining position all the time), thus: 

[Illustration:  Fig. 3.]

[Illustration:  Fig. 4.]

In bars 5 and 6 all cross over again, right shoulder to right shoulder, bringing the side back to back and in original stations.

In bars 7 and 8 all make a full turn to the right (as in Fig. 3) bringing the side again to Front.

As there are two bars to turn in after crossing over, and again after re-crossing, the dancer must, of course, turn slowly and evenly, so that the turn is completed just in time for the jump in bars 4 and 8.

This is called in the Notation—­Cross-over.

BACK-TO-BACK.

As with the Cross-over, this movement is completed in eight bars.

In the first four bars partners advance, right shoulder to right shoulder, but not touching, pass one another, move to the right, re-pass partners (left shoulder to left shoulder), and retire to position, moving backwards.  Thus: 

[Illustration:  Fig. 1.]

In bars 4 to 8 partners advance, left shoulder to left shoulder, pass, move to the left, retire backwards, re-passing right shoulder to right shoulder, and so to original station.  Thus: 

[Illustration:  Fig. 2.]

This is called in the Notation—­Back-to-back.

GO-AND-COME.

This is a form of the Cross-over, but made without turning.  It is executed in Front formation, to eight bars of music.  In the first two bars partners cross exactly as in the Cross-over—­right shoulder to right shoulder.  In bars 3 and 4, instead of turning, retire backwards in the line they crossed—­right shoulder to right shoulder.  In bars 5 and 6 they cross again, but left shoulder to left shoulder, and in bars 7 and 8 retire on the same line—­left to left again.
