Notes:
• Do the entire call without the word Echo; then do the call again without the word Echo and without the first CONCEPT.
• For example, Echo Cross Concentric Spin The Top is a Cross Concentric Spin The Top followed by a Spin The Top (the concept Cross Concentric was removed, not the word Cross).
• Be careful to remove only the first Concept. For example, take L-H Columns and do a Split Phantom Column Circulate Twice. From this formation, consider an Echo Split Phantom Waves Tandem Spin The Top. It would be a Split Phantom Waves Tandem Spin The Top, followed by a Tandem Spin The Top.
• Used with parts-related Concepts, Echo can quickly get difficult.

CONTRAST THE FOLLOWING (from R-H Columns):

• Echo Tandem 1/4 Thru:
1.  Tandem 1/4 Thru;
2.  1/4 Thru.
• Echo Initially Tandem 1/4 Thru:
1.  Initially Tandem 1/4 Thru;
2.  1/4 Thru.
Yes, the above case could be ambiguous, and could be dependent upon the caller's delivery, you might be tempted to just remove Initially. Since Initially requires a following concept, we believe you should remove both Initially and the follow- ing concept. This is similar to the Echo Cross Concentric situation mentioned previously.
• Initially Echo Tandem 1/4 Thru:
1.  Echo Tandem Right Arm Turn 1/4 (Tandem Right Arm Turn 1/4 then Right Arm Turn 1/4)
2.  (Centers) Left Arm Turn 1/2.

Suggestion for callers: Do not use Echo with parts-related concepts at C3B. Only use at C4, and then only sparingly.

The following extensions of Echo are used at C4:

• Double Echo Concept1 Concept2 {anything} [C4]:

• Do the following:
1.  Concept1 Concept2 {anything};
2.  Concept2 {anything};
3.  {anything}.
• For example, from R-H Columns after everyone does a Squeeze: Double Echo Split Phantom Columns Tandem Scoot Back: Split Phantom Columns Tandem Scoot Back; Tandem Scoot Back; Scoot Back.
• Triple Echo Concept1 Concept2 Concept3 {anything} [C4]:

• Do the following:
1.  Concept1 Concept2 Concept3 {anything};
2.  Concept2 Concept3 {anything};
3.  Concept3 {anything};
4.  {anything}.
• Quadruple Echo Concept1 Concept2 Concept3 Concept4 {anything} [C4]:

• Do the following:
1.  Concept1 Concept2 Concept3 Concept4 {anything};
2.  Concept2 Concept3 Concept4 {anything};
3.  Concept3 Concept4 {anything};
4.  Concept4 {anything};
5.  {anything}.
• Reverse Echo {any CONCEPT} {anything} [C4]:

• Do the following:
1.  {anything};
2.  Concept {anything}.
• For example, from a Tidal Wave, Reverse Echo Tandem Spin The Top: Spin The Top; Tandem Spin The Top.
