Overview

Relationship astrology uses four main techniques to analyze the dynamics between two people:

Technique What It Shows Tool
Synastry Interaction patterns — how Person A's planets trigger Person B's planets calculate_synastry_chart
Composite Chart The relationship as its own entity — structure, identity, public face calculate_composite_chart
Davison Chart The relationship's "birth" — inner experience, emotional tone, long-term evolution calculate_davison_chart
Transit Timing When relationship themes are activated get_composite_transit_preview, get_davison_transit_preview

For serious analysis, use all three main techniques plus natal charts. They are complementary layers, not competing methods.


Standard Relationship Reading Workflow

Step 1: Natal Charts (Context)

Call: calculate_natal_chart for each person individually

Understand each person first. What are their core needs, attachment styles, relationship patterns? This provides context for everything that follows. Key questions:

  • What does each person need from a relationship? (Moon sign/house, Venus sign/house)
  • What are their relationship patterns? (7th house, Venus aspects, Saturn aspects)
  • Where might they have karmic baggage? (South Node, Saturn, 12th house)

Step 2: Synastry — Interaction Patterns

Call: calculate_synastry_chart (use karmic_filter=true for karmic focus, significator_filter=true for romantic focus)

Process the summary section:

  1. Top aspects (summary.top_aspects): The 10-15 tightest interchart aspects — these are the strongest interaction patterns
  2. Venus-Mars contacts (summary.venus_mars_contacts): Chemistry, sexual attraction, desire dynamics
  3. Sun-Moon contacts (summary.sun_moon_contacts): Core compatibility, ego-emotion bonding
  4. Saturn contacts (summary.saturn_contacts): Commitment, karma, heaviness, stability
  5. Node contacts (summary.node_contacts): Fated connections, growth catalysts
  6. House overlays: Which of Person A's planets fall in Person B's houses (and vice versa) — shows which life areas are activated

Key Principle: Each person plays the role of their planet in an interchart aspect. If A's Saturn conjuncts B's Sun, A takes on the Saturn role when B expresses Sun qualities.

Step 3: Composite Chart — The Relationship Entity

Call: calculate_composite_chart

The composite chart describes the relationship as its own entity, not either person.

Reading order:

  1. Composite Ascendant: How the relationship presents itself to the world
  2. Composite Sun: Relationship identity and purpose
  3. Composite Moon: Emotional tone, daily rhythms
  4. Angular planets (conjunct ASC, MC, DSC, IC): Loudest voices in the relationship
  5. Key aspect patterns: Especially Saturn, Pluto, Neptune
  6. House emphasis: Which life areas the relationship focuses on
  7. Chart ruler: How the relationship navigates challenges
  8. Unaspected planets: Blind spots in the relationship

Orb guidelines for composite: 3° max (tighter than natal). Sub-1° = defining feature.

Step 4: Davison Chart — Inner Experience

Call: calculate_davison_chart (or calculate_synastry_chart with include_davison_full=true)

The Davison chart is a real chart at a real moment in time (unlike the composite which is purely symbolic). This means it can be progressed and directed like a natal chart.

Composite vs Davison: | | Composite | Davison | |---|---|---| | Nature | Symbolic blueprint | Real moment in space/time | | Shows | Structure, public face | Inner tone, emotional experience | | Best for | How relationship functions | How it feels and evolves | | Timing | Transits | Transits + progressions + solar arcs |

Step 5: Karmic Overlay

Call: get_karmic_relationship_summary or calculate_synastry_chart with karmic_filter=true

See the Karmic Astrology guide for full interpretation framework. Key indicators:

  • Saturn-Node contacts between charts (karmic contracts)
  • Pluto-South Node contacts (intense past-life patterns)
  • Composite/Davison chart emphasizing 8th house (shared transformation)
  • South Node contacts suggesting familiarity from past lives
  • Saturn-heavy composites suggesting serious, destiny-laden relationships

Step 6: Transit Timing

Call: get_composite_transit_preview or get_davison_transit_preview

Shows when relationship themes are activated by transits:

  • Saturn transits to composite/Davison angles: Tests and restructuring
  • Jupiter transits: Expansion and growth
  • Uranus transits: Sudden changes, disruption
  • Pluto transits: Deep transformation
  • Eclipses hitting composite/Davison angles: Fateful turning points

Step 7: Synthesis

Find repeated themes across synastry + composite + Davison. These recurring patterns are the core narrative of the relationship.

  1. Identify the core narrative — What story do all three layers tell together?
  2. Note contradictions — Where do the layers diverge? These are areas of complexity.
  3. Assess karmic weight — How many karmic indicators are present? (Saturn, Pluto, Nodes)
  4. Determine relationship type — Romantic, karmic, business, casual, fated?
  5. Identify growth edges — What are the challenging aspects teaching?
  6. Check timing — What transits are activating the relationship now or soon?

Synastry Aspect Interpretation Quick Reference

Venus-Mars (Chemistry)

Aspect Meaning
Conjunction Intense, obvious physical and romantic attraction
Trine/Sextile Desire and affection flow easily; compatible sexual needs
Opposition Strong magnetism with push-pull dynamics
Square Highly stimulating but prone to friction and fights

Moon-Venus (Emotional Warmth)

  • Creates tenderness, caring, feeling emotionally "fed" by partner
  • One of the best aspects for domestic comfort and feeling cherished
  • Conjunction, trine, sextile = easy flow; hard aspects = needs clash

Sun-Moon (Core Compatibility)

  • Deep understanding at ego and emotional levels
  • Conjunction/trine/sextile: natural "getting" of each other
  • Opposition: complementary but different needs
  • Square: intense attraction with emotional friction

Saturn Aspects (Commitment and Karma)

  • Conjunctions feel fated, dutiful, sometimes heavy
  • Trines/sextiles provide stability and reliability
  • Squares/oppositions bring tests, delays, pressure
  • Not inherently bad — many long marriages have strong Saturn contacts

Node Contacts (Fated Connections)

  • Planets on North Node: destined connection, growth catalyst
  • Planets on South Node: "known you forever" past-life feel
  • Saturn on North Node: karmic teacher relationship
  • Saturn square Nodes: karmic block, timing challenges

House Overlays Interpretation

When Planet A falls in Planet B's house:

  • 1st house: Strongly visible, shapes self-image
  • 4th house: Emotional significance, feeling "at home"
  • 7th house: Partnership significance, embodies relating energy
  • 8th house: Intense psychological/sexual bond
  • 10th house: Public significance, affects career
  • 12th house: Hidden or spiritual connection, can be confusing

Relationship Type Indicators

Romantic / Sexual

  • Venus-Mars aspects (synastry + composite)
  • 5th and 8th house emphasis
  • Moon contacts for emotional bonding
  • Saturn contacts for commitment
  • Pluto contacts for intensity

Business / Professional

  • Mercury contacts for communication
  • 6th and 10th house emphasis
  • Saturn contacts for structure
  • Jupiter contacts for growth
  • Uranus contacts for innovation

Family Dynamics

  • Moon contacts for emotional patterns
  • 4th house emphasis
  • Saturn contacts for duty/parental roles
  • Node contacts for karmic family patterns

Friendships

  • Mercury contacts for intellectual connection
  • 11th house emphasis
  • Jupiter contacts for shared optimism
  • Uranus contacts for unconventional bonds

Common Mistakes

  1. Reading composite as a natal chart for one person — The composite describes the relationship entity, not either person.
  2. Treating difficult aspects as relationship doom — Hard aspects create friction that can strengthen the relationship.
  3. Reading composite in isolation — Always use with synastry + natal charts.
  4. Ignoring house overlays — They show which life areas are most activated by the relationship.
  5. Overemphasizing Venus-Mars — Chemistry is important, but Sun-Moon and Saturn contacts determine long-term compatibility.
