Illuminating Relationships: Composite & Davison Charts

Once an understanding of individual relationship style is understood via the natal chart, we begin an analysis of the synastry or inter-connections between two charts. The final step in astrological relationship work is using the combined charts. The most popular of these are the Composite Chart and the Davison Relationship Chart.
