Relationship Astrology — Agent Interpretation Guide
For agents using the astro MCP to perform relationship chart interpretation.
Overview
Relationship astrology uses four main techniques to analyze the dynamics between two people:
| Technique | What It Shows |
|---|---|
| Synastry | Interaction patterns — how Person A's planets trigger Person B's planets |
| Composite Chart | The relationship as its own entity — structure, identity, public face |
| Davison Chart | The relationship's "birth" — inner experience, emotional tone, long-term evolution |
| Coalescent Chart | Harmonic responsiveness to transits (rarely used) |
For serious analysis, use all three main techniques plus natal charts. They are complementary layers, not competing methods.
Reading Workflow
Step 1: Natal Charts
Understand each person individually first. What are their core needs, attachment styles, relationship patterns? This provides context for everything that follows.
Step 2: Synastry
Analyze the interaction patterns between the two charts:
- Tightest interchart aspects (tightest orbs = most significant)
- Venus-Mars contacts (chemistry)
- Moon contacts (emotional bonding)
- Saturn contacts (commitment, karma, heaviness)
- Node contacts (fated connections)
- House overlays (which life areas are activated)
Step 3: Composite Chart
Analyze the relationship as its own entity:
- Composite Sun (identity and purpose)
- Composite Moon (emotional tone)
- Angular planets (loudest voices)
- Key aspect patterns (especially Saturn, Pluto, Neptune)
- House emphasis (life area of focus)
Step 4: Davison Chart
Analyze the relationship's inner experience:
- Same approach as composite but focused on emotional/internal tone
- More accurate for timing techniques (progressions, solar arcs)
- Use for long-term evolution tracking
Step 5: Synthesis
Find repeated themes across synastry + composite + Davison. These recurring patterns are the core narrative of the relationship.
Synastry Interpretation
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. Think of it as a dance where each person activates different roles depending on context.
Interchart Aspects: 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, dutious, 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
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
Orb Guidelines
- Personal planets (Sun through Saturn): 5° max
- Outer planets: 3° max
- Tighter orbs = stronger effect
- Using significance scoring: conjunction/opposition > square > trine > sextile
Composite Chart Interpretation
Key Principle
The composite chart describes the relationship entity, not either person. Composite Moon in Scorpio doesn't mean either person is emotionally intense — it means the relationship itself has that quality.
Reading Order
- Chart shape: House clusters (upper/lower, east/west hemispheres)
- Composite Ascendant: How the relationship presents itself
- Composite Sun: Relationship identity and purpose
- Composite Moon: Emotional tone
- Angular planets: Loudest voices
- Most-aspected planet: Recurring theme
- Unaspected planets: Blind spots
- Chart ruler: How the relationship navigates challenges
Composite Planet Meanings
| Planet | Meaning in Composite |
|---|---|
| Sun | Core identity and purpose of the relationship |
| Moon | Emotional tone, comfort, daily rhythms |
| Mercury | Communication style as a couple |
| Venus | Love style, affection, shared values |
| Mars | Drive, passion, conflict style |
| Jupiter | Growth, optimism, shared beliefs |
| Saturn | Structure, commitment, tests |
| Uranus | Unpredictability, freedom, innovation |
| Neptune | Idealism, spiritual connection, illusion |
| Pluto | Power dynamics, transformation, depth |
Composite Aspects
- Orbs: 3° max (tighter than natal). Sub-1° = defining feature.
- Saturn aspects: Structural foundation. No Saturn = free but unstable. Strong Saturn = enduring but demanding.
- Pluto aspects: Power struggles and transformation potential.
- Neptune aspects: Idealization risk. Watch for disillusionment when glamour fades.
- Sun-Saturn conjunction: Core defining feature — serious but potentially very long-lasting.
Common Mistakes
- Reading composite as a natal chart for one person
- Treating difficult aspects as relationship doom
- Reading composite in isolation (always use with synastry + natal)
Davison Chart Interpretation
Technical Note
The Davison chart is a real chart at a real moment in time (midpoint of two births), 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 |
Practical Staging
- Synastry → when people first meet
- Composite → once relationship forms
- Davison → once formally committed
When They Differ
Look for repeated themes across both. They are "two versions of the same story." Same planets emphasized, similar house themes = core relationship narrative confirmed.
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
Timing Relationship Events
Composite/Davison Transits
- Saturn transits to composite angles: Tests and restructuring
- Jupiter transits to composite angles: Expansion and growth
- Uranus transits: Sudden changes, disruption
- Pluto transits: Deep transformation
- Eclipses hitting composite angles: Fateful turning points
Transit Preview
Use the astro MCP's transit preview capability on the composite and Davison charts to identify windows of activation.
Karmic Relationship Indicators
(See karmic-agent-GUIDE.md for full detail)
Key Indicators Across All Three Layers
- 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
Synthesis: Building the Narrative
When synthesizing a relationship reading across all layers:
- Identify the core narrative — What story do all three layers tell together?
- Note contradictions — Where do the layers diverge? These are areas of complexity.
- Assess karmic weight — How many karmic indicators are present? (Saturn, Pluto, Nodes)
- Determine relationship type — Romantic, karmic, business, casual, fated?
- Identify growth edges — What are the challenging aspects teaching?
- Check timing — What transits are activating the relationship now or soon?
