The Resonance Identikey (from Compatikey.com)
The Resonance is one of the Dynamic Identikeys. The Resonance result
represents information that describes the tone, intensity or nature of a heart centered connection (not to be confused with love) felt between the Selected Member and another person. We like to call this Identikey the "aahh" factor!

It is expressed as three side by side icons, each position representing a specific combination between you and another.

Each position in the result can be one of these three possible icons representing an intensity level ranging from 1 do 3, with 3 being the highest intensity. Note: No one level is better than any other, it is up to you to use your experience to reveal a possible preference.
 

Icon Level Represents

Level 3 Resonance

Sameness

Level 2 Resonance

Middle ground
Level 1 Resonance Difference

Position 1: Represents one side of a shared resonance in that relationship.

Position 2: Represents the other side of a shared resonance in that relationship

Position 3: Represents a mutual Resonance felt between the Selected Member and the other person in a relationship. 

In a Resonance result, think of positions 1 and 2 as two sides of a coin.
You'll each experience both sides of the coin.
Both sides of the coin being the same,  and both sides of the coin being different, are different experiences. 

Here are the 3 possible results of a same Resonance between positions 1 and 2 :

Same Resonance

Both Level 1

Both Level 2

Both Level 3

Here are the 4 possible results of a single level different Resonance between positions 1 and 2:

Resonance Different by a Single Level

level 1 level 2 level 2 level 1 level 2 level 3 level 3 level 2

Here are the 2 variations of Resonance different by 2 Levels:

Resonance Different by 2 Levels

level 3 level 1

level 1 level 3

Position 3 is a mutual resonance.
Staying with the coin metaphor, if positions 1 and 2 represent two sides of the coin, then position 3 would be what both sides of the coin have in common, ...the edge of the coin.

In the following example, position 3 makes a difference in the two experiences.  There's a little more sameness in the second result. Depending on the relationship, you may or may not be aware it!
