# Chord statistics
See statistics of tones in- and out-of-key, related to the mode of your song.
To quickly see which quality the chord has and if the chord is within the current key, the app has an **"Out-of-key indicator"**. You will find the indicator next to the chord:
{% hint style="info" %}
The **inner-circle** shows the quality (major, minor etc.) of the chord indicated by the circle's color. [**Read more about colors.**](/general/general-info/colors.md)
{% endhint %}
{% hint style="info" %}
The **outer-circle** shows how many tones of this chord are out of the key. For each tone that is not in key, you will see a little dot placed on the outer-circle.
{% endhint %}
**Examples:**\
You can see them also in the app under "General information".
{% hint style="info" %}
**Tap in this icon** to reveal even more information about the chord or the chord suggestion.
{% endhint %}
