A composite chart is a type of astrology chart that combines the natal charts of two individuals to create a single chart that represents the relationship between them. It is created by calculating the midpoints between the same planets and points in each person’s natal chart. For example, if Person A has the Sun at 20 degrees Aries, and Person B has the Sun at 20 degrees Gemini, the composite Sun would be at 20 degrees Taurus.
A composite chart is a type of astrological chart created by what they create when they work together. Not so much how they get along, or how compatible or romantic they are, but how they act together as a unit.
It is important to remember that a composite chart is only one tool in the astrological toolbox and should be used alongside other techniques, such as synastry to gain a comprehensive understanding of a relationship.
