Composite Midpoint Charts: Overview

Midpoints

Two points on a circle will generate two midpoints, the nearer midpoint and the farther midpoint.

Natal Midpoints

A natal midpoint is the point between two planets (Sun, Moon, Mercury etc.) or chart points (Ascendant or North Node, etc.). For example, in a natal chart you can calculate the midpoint between the Ascendant and the Midheaven.

Composite Midpoints

Composite midpoints are formed by the midpoint of the same planet from two (or more) different charts.

Nearer Midpoint

If the first person’s natal Sun is at 5° Libra and the second person’s natal Sun is at 5° Leo, then the composite Sun will be at 5° Virgo. There is also a midpoint at 5° Pisces, but we always use the nearer midpoint.

Computer Generated Composite Midpoint Charts

Solar fire and Astro Gold will calculate composite midpoint charts for you. However, it is important to check the placements of the planets and aspects to the angles as they are sometimes shown as the opposite to that which you would expect.

How to Calculate a Composite Midpoint Chart Computer Calculations

Astro Gold and Solar fire will calculate a composite midpoint chart for you. However, as an Aspiring Astrologer you ned to know how to do it manually. Here is the sequence to manually calculate a composite midpoint chart for two people..

House Cusps in a Composite Chart

The composite Ascendant and the house cusps are calculated differently. Initially we find the Midheaven midpoint and then back calculate the house cusps in the Table of Houses for the location that the relationship is taking place. Unless you are doing manual calculations, the computer will take care of this.

Calculating the Composite Planets

Take both persons Sun’s longitude position and find the midpoint between the two Suns. Place that new composite Sun in the correct position in the composite chart.

Composite Midpoints Special Considerations Chart Calculation Defaults

It is important to measure apples to apples and not apples to oranges. Before you create a midpoint, composite chart make sure both natal charts are cast the same way and they are set for:

  • The same zodiac(tropical or sidereal
  • The same house system (usually Placidus)
  • The same node calculation (true or mean)

When the Natal Planets are Opposite

When natal planets are more than 150° apart between the two charts, you may want to consider both composite planetary positions, that is the nearer and the farther midpoint.

Planets in Signs in Composite Charts

Do not give much value to the sign positions of the planets in the composite charts. It is more useful to consider the planetary house positions, aspects and aspect patterns when interpreting these charts.

Composite Retrograde Planets

One person’s natal chart could have a direct Jupiter. and another person’s natal chart could have a retrograde Jupiter. We usually ignore retrograde motion when using composite charts.

Group Composite Charts

Although composite charts are usually done for a couple, you can cast a composite chart for three or more people. In group charts you see the dynamic of the group or unit.

Example 1

You may cast a composite chart for you and your partner who live in your home. When Granny decides to move in, you can cast the new composite chart with three natal charts to see how things will improve or deteriorate as a third person is added to the home.

Example 2

You may consider creating a four-way partnership at work, or perhaps for a music band. You can cast the composite chart for all four potential members to see how the partnership will change as more people are added.

In group composite charts look to the major aspect patterns that drive the chart for quick information.

Composite Chart Inner Planet Paradox

One paradox in composite planetary position calculations is that the composite Mercury or Venus can sometimes end up on the other side of the chart to the Sun.

This paradox can cause for example, the incorrect aspects of:

  • Sun opposition Mercury.
  • Sun opposition Venus.
  • Mercury opposition Venus.

The suggested solution to this paradox is to take the composite Sun’s position (the nearer midpoint) and, if the inner planets are on the wrong side of the chart, move the inner planets directly opposite the calculated composite Mercury and Venus position (the farther midpoint), and thus near the Sun’s position.

The Sun always is the magnet for Venus and Mercury.

Brad Pitt and Angelina Jolie’ Compoiste Midpoint Chart

Venus’ position at 25°48′ Libra is the nearer midpoint. Use the futher midpoint for Venus at 25°48′ Aries. Angelina’s natal Venus is at 28°09′ Cancer and Brad’s natal Venus is at 23°28′ Capricorn. They are in opposite signs and are in fact nearly opposite each other.

The Angles in the Composite Chart

Remember the composite Midheaven and composite IC are both midpoints generated from the two individual charts. Whereas the composite Ascendant/Descendant axis is back calculated from the Midheaven position in the Table of Houses. This indicates that the composite Ascendant is not as important as in natal astrology and one should focus on the condition of the MC/IC angles.

Composite Ascendant

  • Indicates the “face” of the pair shown to the world.
  • Suggests the image they would like to project as a couple.

Composite Descendant

  • Shows the true nature of the relationship.
  • Indicates what brought them together in the first place.

Composite Midheaven

  • Shows how the world views this couple’s relationship.
  • A strong Midheaven indicates they are a public couple and well thought of and respected by others.

Composite IC

  • This shows how the couple are in the privacy of their own home.
  • Suggests the foundations of the relationship.

Composite Charts Interpretation Sequence

Remember the composite chart shows the relationship and not the individuals that formed it. You always need to have interpreted the two natal charts first to glean what each individual wants in a relationship and who they hope to attract.

In composite charts consider:

  • Any house emphasis
  • The luminaries houses
  • The luminaries aspects
  • Any planets conjunct the angles
  • Venus and Mars’ house positions and aspects
  • Any 7th house planets
  • Saturn by house and aspects
  • The other planet’s houses
  • The other planet’s aspects
  • The aspect patterns

Forecasting with a Composite Chart

The usual forecasting techniques of transits, secondary progressions and solar arc directions can be applied to a composite chart. It is not recommended to produce a solar return chart for a composite chart as the Sun’s position in the zodiac is already an extrapolated position. However, you may certainly attempt some research in this regard.

The Composite Vertex

The vertex in composite charts shows the sphere of experience that will be most significant for the couple, and the destiny of the relationship and to where the relationship is eventually going. We always need to consider that any relationship may have another purpose than that which we would normally expect. For example, two people who are married may not love each other anymore but both find solace or friendship within the actual relationship.

What to look for in the composite vertex:

  • A well placed vertex in the composite chart indicates this relationship is having a great effect on the couple and them as individuals.
  • Conjunctions and oppositions need careful consideration.
  • Use a 2° orb.
  • Do not consider the vertex house position heavily. Remember in a natal chart the vertex is typically only found in the 5th, 6th 7th and 8th houses.

Aspiring Astrologer Activity

Using the composite midpoint chart between yourself and your partner:

  • Determine if the inner planet paradox in present in this composite chart. If so, what will you do?
  • List the house positions of the composite planets (not signs).
  • Determine the Ptolemaic aspects in the compositechart.
  • Find any composite major aspect patterns (stellium, grand trine, grand cross, T-Square, Thor’s hammer, yod, cross of David, mini grand trine or mystic rectangle) and write a short interpretation for the pattern. (100 words)
  • Find the most emphasized composite house and briefly comment on the tenants and house meaning in regard to the relationship. (100 words)
  • Note if the emphasized composite house echoes the same houses in the two natal charts or if this a new emphasized house only showing in the relationship and comment. (50 words)
  • In a few sentences describe the composite chart ruler complex exploring the house (not the sign), essential dignity and if it is most elevated, oriental or the almuten and consider all the aspects. (100 words)
  • Note your feelings about this composite chart and how it describes the relationship between you and your partner. (50 words)

Extend Yourself

As an Aspiring Astrologer, to really get to grips with the principles of midpoint composite charts, you can extend yourself.

  • Cast a couple’s two natal charts and only by looking (no arithmetic calculations) decide which sign (and maybe degree) their composite planets will be. Check yourself against the computer calculations.
  • Cast the composite chart for your parents by hand. Do the manual calculations (arithmetic on paper) to see what you can create, then check your manual hand drawn chart against the computer results.
  • Cast a chart for three people that you know by hand. You could use your family member’s natal charts. See what happens to the composite chart as one person is added (when granny moves in) or taken away (when a young adult finally leaves home).
