Through studying the composite chart of a relationship, we can gain important insights into the dynamics of a couple. The composite chart is the chart of the relationship itself. It is derived by determining the mathematical midpoints between each person’s planets and points, and is an entirely new chart altogether—the chart of a relationship. Basic relationship dynamics can be seen in the composite chart.
As is the case with a natal chart, we must work with the energies in place, rather than submit to being ruled by them. We can learn to harness the energies created by the more difficult aspects in a composite chart, and to appreciate the positive energies bestowed upon us.
Relationships are not static—they move and develop with time. As such, not all aspects and positions in the composite chart will be overt or apparent at the outset of a relationship. There are some advanced techniques that some astrologers use to gain a better understanding of the evolvement of the relationship, including transits to the composite chart and progressing or directing the chart to a date beyond the initial meeting. However, there are some things we can look for in the composite chart itself.
For example, the composite Ascendant can indicate the circumstances surrounding the first meeting or the beginning of the relationship. It can also point to how a couple initiates things together (such as projects). Similarly, the end of a relationship can be depicted by the composite twelfth house. Once a relationship kicks in (moves beyond the initial stages), the composite Sun becomes more apparent. If a commitment to each other happens, the seventh and eighth houses come more clearly into focus. As such, the conditions surrounding the planets and houses in the composite chart can show us different stages of development of the relationship over time.
We must pay attention to such factors as predominance or lack of aspects, and unaspected and most-aspected planets. For example, an unaspected Sun in the composite chart can indicate a feeling that the relationship lacks direction. There may be difficulty seeing where the relationship is heading, and there can even be questions as to why it exists in the first place.

Challenges and Growth
Neptune in hard aspect (including the conjunction) to personal planets in the composite chart can be highly challenging in my experience with composite charts. They generally play out over time. What starts as an almost idyllic relationship can turn sour and even bitter over time. Why? A strong Neptune can feel downright wonderful at the beginning, until reality starts to seep in. The couple may idealize each other, in different ways, and the wonderful first impressions can be hard to live up to.
Let’s say there is a Moon opposition Neptune in a composite chart. We can see that potential for disappointment is connected with the composite Moon—the emotional pipeline of the relationship. At the beginning of the relationship, there can be a very strong feeling of familiarity and comfort, and an emotional connection that seems out of this world. The problem that can arise from the elation the couple feels on an emotional level can stem from the perceptions of each individual involved, and the expectations they develop in the early stages of the relationship. When elation brings you very high, the fall is hard. Some of the initial feelings that a comp. Moon opposite Neptune can generate include feeling like one’s partner is the most supportive person one has ever met, for example. Over time, that partner will falter and stumble in the emotional department, as he or she is human. The problem with Neptune is that the expectations can be so great that they are inhuman. Another problem with Neptune is a lack of definition. Misunderstandings between individual expectations of the partnership are often the result of unclear communication. Sometimes, there is outright deception involved, but most of the time it is nothing of the sort. Neither party means to promise more than he or she can deliver, but they may be guilty of trying to fill the shoes of the ideal image that has been set up for them, and tip-toeing around hard cold facts or commitments.
If that same composite Moon opposition Neptune receives a supporting trine and sextile, for example, from Mercury conjunct Pluto, then we have an escape line. (Although, since we are talking about Neptune, “escape” would probably not be a good way of putting it. Handling Neptune effectively involves facing facts and making definitions, rather than escaping problems). There is a clear opportunity to get past the challenge of the opposition. In this case, Mercury conjunct Pluto suggests an ability to talk things through and get to the heart of the matter. Here, the couple has a clear opportunity to work through the challenges of the opposition, and the tools they have are their willingness to find meaning and growth opportunities in their relationship.
Mind you, Mercury conjunct Pluto has challenges of its own. On the one hand, psychological understanding, and a willingness to delve more deeply into attitudes and thought patterns of one another, can help the couple grow. On the other, there may be a tendency for communication between the two to be too weighty, too serious, and even compulsive. An especially negative manifestation of this whole configuration might be a compulsive (Pluto) desire to define (Mercury) the meaning of the relationship on the level of emotional attachment (Moon), but either one partner avoids (Neptune) the confrontation altogether, or if he or she does confront it, the other person misinterprets (Neptune) their partner’s answers in an attempt to see what he or she wants to see (Neptune). With Pluto connected to Mercury, there may be a desire to direct the thoughts of one’s partner, molding them into what he or she wants (Neptune) to hear. This is just one possible manifestation that serves as an example.
The composite chart quite vividly reveals some of the dominant dynamics in a relationship. Just as with a natal chart, the composite chart will contain apparent contradictions. It may contain, for example, Venus trine Mars and Sun square Mars. Venus trine Mars suggests an easy flow of creativity, and a non-competitive nature to the relationship. On the other hand, Sun square Mars suggests some real disruptions and clashes. These potentials exist simultaneously. They are always present, but each aspect will be expressed more overtly in certain situations and circumstances. When we talk of situations and circumstances, as students of astrology, we often will immediately look to houses of the chart.
We can read the houses in the composite chart in a similar manner as we do the houses of a natal chart, except we must keep in mind that we are reading the chart of a couple. Let’s take again the example of a composite Sun square Mars. What if Mars is found in the eleventh house and Sun is in the 8th? The clash of Sun and Mars has a context when we factor in the house placements. Two powerful yang planets, the Sun and Mars, are found in houses that represent two different experiences. On the one hand, we have an objective-oriented Sun in the house of personal intimacy. On the other, we have the very strong pull of Mars in the house of individuality! We might expect that partnership goals will be a bone of contention in the partnership. Intimacy vs. individuality may be a common theme of the couple’s disagreements.
Our study of the composite Moon opposition Neptune aspect mentioned above can have more meaning when we consider the house positions of these planets. If Neptune is in the 11th house, for example, we might assume that the tendency towards misunderstandings and delusions, and a lack of boundaries and definition, may be most obvious in eleventh house experiences or circumstances. We can factor in issues of individuality and freedom, for example. The emotional connection that the couple feels—that connection that feels “out of this world”—may lack definition in terms of how free each individual is to be himself or herself, to act in an independent and objective manner (eleventh house). Perhaps any kind of expression/display of independence and objectivity on the part of one person in the relationship will feel threatening to the other. The composite Moon in the fifth house is very personal and subjective. Although the fifth house is not as deeply intimate as the eighth house, its energy is such that it demands a personal and special bond. When it meets the objectivity of the eleventh, a house that sees everyone as a potential friend, not just one special person, there can be a perceived threat. With the fifth house composite Moon, and Neptune challenging that Moon, there is an unspoken (but very present) script for the emotional level of the relationship.
When Pluto is prominently connected with personal planets in the composite chart, we can find issues with compulsive control in the relationship. With a heavy Moon-Pluto composite aspect, for example, the relationship is likely to possess a theme of emotional manipulation. Games are played, and there can be emotional smothering and frequent issues with possessiveness. Even Mercury-Pluto aspects can represent some kind of attempt to mold one another into thinking a particular way. Partners should be reminded that the fear of loss of one another can easily become a self-fulfilling prophecy if tactics and games are used to try to “keep” a person, or to enforce some kind of dependency on each other. When Pluto is connected with personal planets in the composite chart, and is playing a supportive role, the connection can be intense but not quite so overwhelming.
House Emphasis in the Composite Chart
The position of the planets in the composite chart by house is significant and should be considered. We can study each planet’s position by house, and we can also zero in on any houses that are especially occupied in the composite chart. Three or more planets in a house, especially when the Sun and/or Moon are involved, can certainly be considered an emphasized house. A strong composite first house, for example, can suggest a couple who is quite concerned about how others think of their relationship. They need to be wary of getting too caught up in their image as a couple and neglect the inner workings of their partnership. It also represents a very strong image of the relationship. The people may feel more powerful in the relationship than they do on their own. An emphasized composite second house might suggest a relationship that is built on security reasons. This relationship may have an obvious practical side to it so that it seems a bit like a business arrangement even if it isn’t a business set-up. They need to rely on each other, and if the planets in the second house are well-integrated, they feel like they can count on each other.
An emphasized composite fifth house points to a focus on the fruits or creations of the couple, which can often be the children of the marriage. The condition of the composite fifth house can suggest how much enjoyment the couple derives from the partnership–how much fun they have. A challenged composite fifth house (perhaps one that has Saturn or Pluto, for example, posited in the fifth or challenging planets in the fifth) can point to problems with self-expression in the partnership. The individuals involved may feel that the partnership doesn’t allow them to have fun or it stifles their creative growth. A well-integrated and strong fifth house in the composite chart, on the other hand, can point to a highly romantic, creative, and fruitful partnership.
Comparing the Composite Chart to the Natal Chart
In my notes above, I mention that I look to see if the personal planets in a composite chart conjunct any of the personal planets or points in each individual’s natal chart. If you are studying a relationship in-depth, you might also consider taking this concept further. The composite chart is a chart of the relationship itself, and reveals the specific dynamics of that relationship. As such, we can conceivably compare natal charts to the composite chart in order to see how the relationship itself impacts an individual, and vice versa. This individual can be either of the individuals involved in the relationship—but it can also be someone else altogether! For example, when analyzing family dynamics, it can be revealing not only to study the synastry between mother and child and between father and child. We can also compare the child’s chart to the composite chart of the mother and father in order to see what kind of impact that relationship has on the child—and the child’s impact on the relationship!
In these kinds of analyses, sometimes the symbolism is very literal. For example, parents of a friend of mine had divorced because her father had had an affair with another woman, whom he later married. My friend had birth data for both of her parents and the “other woman”. The degree of the other woman’s Sun was exactly conjunct the married couple’s composite Sun. In this case, the other woman’s birthday fell at the midpoint of the couple’s birthdays, symbolically “coming between” the couple.
What does the relationship itself mean to an individual involved in that relationship? Overlay the composite chart of that relationship onto the natal chart of the individual to find some answers. An example from my files: my female client explained that her relationship with a man had started off quite passionate, but when it began to “fall apart” (on an intimacy level), and it was headed for a break-up, the man insisted that although he accepted that the relationship should cool off, he felt that they should continue to talk on the phone once in a while. Why? He explained that he felt that when they talked to each other about problems, they often came to some very workable solutions. The composite Sun (which represents the purpose of the relationship) conjuncted his Mercury in his 10th house! To him, the brainstorming (Mercury) between the two amounted to something very usable and worthwhile (tenth house).
Going with this concept, there are many different possibilities. If, for example, the composite Sun of the relationship falls on an individual’s IC (fourth house cusp), the relationship may be almost primal to the person. It may easily become habitual. This person is likely to be attached to the relationship in a very basic way, and might have a hard time believing he or she can exist without it. If many of the personal planets and Ascendant in the composite chart fall in an individual’s second house, he or she may consider the relationship to be a vehicle through which he or she can find some security—not only financial security, but also a sense of grounded-ness and usefulness is derived from the relationship. If composite Jupiter falls on one individual’s Ascendant, he or she might feel the relationship augments his or her personal reputation with others, or it gives him or her a sense of personal well-being that is measurable.
If you would prefer to “cut to the chase” in this particular analysis, you might decide to note only the Composite Sun and where it lands in each individual’s chart, suggesting each individual’s perception of the purpose of the relationship.
Besides examining the synastry between each individual’s natal chart and the composite chart of the couple, we can also compare the overall feel of the composite chart with the natal charts of the individuals involved. If one of the individuals involved has one planet in his eighth house, and that planet is Saturn, for example, and the composite chart reveals a heavily-posited eighth house, the relationship itself may be very attractive to this person at the beginning, but might later feel overwhelming and draining. Sometimes we will see individuals with strong house emphases in their charts that are entirely different than the emphases in the composite charts. This can be exciting, indeed, as the relationship offers new, uncharted avenues of expression for the individuals involved.
Composite Chart Interpretation
Getting into the composite chart “frame of mind” involves wrapping our minds around the fact that the chart is of a relationship as a third entity. Keep in mind that a composite chart is a midpoint chart. It is where two people come together, and how they combine.
Even so, people can take on the roles of, or play out, certain planets or energies within the composite chart. We like to assume that both men and women “own” the Sun and Moon, which represent the yang and yin (masculine and feminine) energies respectively. However, it is also obvious in some situations that the man in a relationship may vibrate to the Sun energies more readily than he does the Moon energies in the composite chart, and he can often take on the role of the Sun in the composite chart as a result. Similarly, the woman in the relationship may be more attuned to the composite Moon. We cannot go so far as to say that the composite Sun represents the man in a relationship and the Moon represents the woman in a relationship, but if you study composite charts long enough, you will see this attunement happen often enough. So, in some situations, if for example there is a Sun conjunct Saturn in a composite chart, it may not only represent a relationship that has a distinct air of practicality, it can also suggest that expression is restrained or forced, especially on the part of the man. Another example (from my files) reveals a composite Sun that squares Mars, while the composite Moon forms a number of trines to Jupiter, Mercury, Uranus, and Pluto, as well as an opposition to Neptune. In this particular example, the woman enjoyed the relationship so much more than the man did. He found their relationship strained and combative, while the woman felt that the relationship opened up many avenues of expression (represented by the trines). She saw so much more potential to the relationship than the man did. The opposition of the Moon to Neptune did represent her subsequent disappointment and disillusionment when the relationship dissolved and she was left wondering why the man was so willing to give the relationship up.
Although situations like the one in the example above do occur, we really have no idea “who is who” in the composite chart unless we consult with the individuals in the relationship. Usually, there is no “who”, but some individuals do “tune in” to certain vibrations in the composite chart. We can also note if any planets in the composite chart conjunct planets or points in the natal charts of the individuals involved. If, for example, a man’s Sun and Mercury are found within 1-2 degrees of the composite Venus, he may tune into the composite Venus vibration more naturally, and act out its aspects. Another example would be if a woman has Mars in Capricorn natally, and the composite chart includes a Mars conjunct Saturn, she may play out that composite aspect.
Composite Planets in the Houses
The following interpretations are far from comprehensive. Some possible themes are discussed. How these positions will play out will depend on the aspects the planet makes, as well as which houses and positions the planet rules. Keep in mind, as well, that there are positives and negatives of every position. Please note that some of the interpretations are not yet available.
Planetary Aspects in the Composite Chart
The influences of the aspects between planets in the composite chart can be considered the heart and soul of the relationship. Although any composite chart is complex, with multiple influences to consider, it’s helpful to study each planetary aspect in order to understand the energies at play in a relationship.
Often, themes in a chart comparison (synastry) repeat in a composite chart reading. However, there are times when strong themes don’t repeat. One of the main differences between comparing charts and reading composite charts has to do with the fact that the composite chart is the chart of a couple–it represents the relationship as a unit. Comparing charts, on the other hand, involves comparing the different energies of two charts point by point. Another way to look at it involves viewing the composite chart as the “final outcome” of the relationship. Take, for example, a situation in which hard aspects of Neptune are present in the chart comparison of a couple, but Neptune is not similarly strong in the composite chart. Issues regarding disillusionment and/or deceptions will be a part of the relationship, but won’t be a deciding factor when it comes to the viability of the partnership. If hard aspects of Neptune figure strongly in the composite chart and not in the chart comparison, on the other hand, difficult Neptunian themes may seem to erupt out of nowhere and become a major factor with regard to the viability or outcome of the relationship. In some cases we find, for example, mutual hard aspects between each person’s Venus and Mars in chart comparison. In the composite chart, however, there is a Venus-Mars harmonious trine. In a situation such as this one, sexual tension represented by the Venus-Mars hard interchart aspects is most certainly present in the relationship. However, overall, the couple finds creative solutions to the tension. It is unlikely that the challenges created by the interchart aspects will reign in the partnership. Overall, both individuals will find the relationship largely satisfying on romantic and sexual levels. If the couple were to break up, the tensions created by the hard Venus-Mars aspects wouldn’t be a factor in the separation. In fact, the composite Venus-Mars trine could be one factor that keeps them together. As such, it is important to consider the challenges in a composite chart as factors that directly affect the viability of the relationship and the quality of life of a couple. Synastry aspects represent interplays that certainly exist and are relevant. However, the composite chart helps to pinpoint the more “fatalistic” potentials and challenges in a relationship.
Asteroids in the Composite Chart
Adding asteroids and other “non-standard points” to the composite chart brings more detail to composite chart analysis. Look to Eros for mutual passions, erotic connections, and obsessions in the relationship, for example. Look to Psyche for intuitive connections. Look to Juno for “me-you” relationship power dynamics. Look to Ceres for nurturing connections. Look to Vesta for dedication and commitment. Asteroids can be read much like other planets — in terms of aspects they make to each other, as well as their placement by house. You need to know the basic meaning of each asteroid in order to understand how they function. For example, a troublesome Eros in the composite chart could be indicative of the need for seemingly constant attention and feedback from one another. The erotic, lusty connection between you can produce conflicts. A strong, mostly positive Vesta can indicate a strong feeling of dedication and commitment to one another. A strong, challenged Vesta might suggest conflicts arising from your dedication to one another or to the relationship itself.
