9th Harmonic

9th Harmonic

What your 9th Harmonic can reveal

Some relationships between planets go almost unnoticed in a classic reading of a birth chart. Yet they can take on new importance when you look at the same chart through its harmonics.

The 9th Harmonic is obtained by multiplying the zodiac longitudes of the planets by nine, then bringing the result back within the 360° of the zodiac.

This transformation reveals new configurations and highlights relationships linked to dividing the circle into nine parts.

Traditionally associated with maturation, commitment and deep bonds, the 9th Harmonic offers a complementary reading of your birth chart.

A new way of looking at your planets

In your birth chart, two planets may seem far apart or form no major aspect.

In the 9th Harmonic, their relationship can become much more visible.

Astraema recalculates their positions and shows them on a new chart wheel, so you can observe the configurations that emerge from this transformation.

The Navamsa: a Vedic astrology tradition

In Indian astrology, dividing the zodiac into nine parts is the basis of the Navamsa, also called the D9 chart.

Depending on the interpretive tradition, this chart plays an important role in the study of marriage, commitment, maturation and dharma.

Astraema lets you explore this harmonic division within its own astrological calculation system.

Whole sign houses

For the 9th Harmonic, Astraema uses whole sign houses.

Each house corresponds to one complete sign, which gives the chart wheel a distinctive structure and makes the house positions easier to read.

Several chart wheels to compare configurations

The 9th Harmonic can be studied on its own, but also in relation to your birth chart.

Astraema lets you layer up to three chart wheels, combining your 9th Harmonic with your birth chart, your progressed chart or the transits for a given date.

So you can see how the harmonic's configurations connect with the other astrological positions.

A chart wheel tailored to your exploration

As with Astraema's other calculations, you can choose a classic, karmic or angle-focused view.

Focus lets you isolate a planet and its aspects. Up to three objects can be selected at once to examine how they interact.

Another reading of your natal positions, to explore astrological links that are less visible in the classic chart.

The 9th Harmonic uses the Whole Sign house system. This is the traditional Navamsa method: each house corresponds exactly to one sign, starting from the sign where the harmonized Ascendant falls.
In Vedic astrology, whole sign houses are traditionally used.
