# Modalities

In astrology, **Modalities** describe the different ways each [zodiac sign](/docs/astrology-and-alchemy/signs.md) expresses its energy and approaches life. There are three **Modalities**: Cardinal, Fixed, and Mutable. Each Modality includes four [zodiac signs](/docs/astrology-and-alchemy/signs.md), and these groups help us understand how the [signs](/docs/astrology-and-alchemy/signs.md) act, react, and adapt to different situations.
