Composite chart
A composite chart is a single chart built from the midpoints between two people's planets, read as the chart of the relationship itself rather than of either person.
Where synastry keeps two charts and studies the contact between them, the composite makes a third: its Sun is the midpoint of the two Suns, and so on around the chart.
The Davison chart is the related alternative, built from the midpoint in time and space rather than in the zodiac, and our report prints both.
Frequently asked
Is the composite better than synastry?
Neither is better: synastry describes how two people meet, the composite describes what the relationship is like as an entity.
What is the difference from a Davison chart?
The composite averages positions; the Davison averages the birth moments and places, producing a real chart for a real time.
