Other often-used concepts are

As Couples, Once Removed, Stable, Twice, and Twosome.

Occasionally, an identifier such as 'Centers' is used as the concept. For example, from R-H Twin Diamonds: Random Centers Recycle (Centers 1/3 Recycle; all Split Counter Rotate 1/4; Centers Roll). This is hard!

To successfully execute 'Random' calls, you need to learn the parts to the commonly used calls.

For example, 'Swing & Mix' and '1/4 Mix' have 3 parts, not 2.

Commonly used 4-part calls include 'Change The Wave', 'Change The Centers', and 'Reset'.

It also helps to verbalize 'Tandem', 'normal', 'Tandem', etc. while you're doing the call.

Take your time, and don't rush it.

If there's only two parts to the call, Random is the same as Initially.

The Random concept has been renamed to the Oddly concept.
