In astrology, harmonics is a special way to study the relationships and interactions of the planets with each other, using mathematical divisions of the zodiac. This technique helps us to delve into the hidden aspects of personality, potentials and tendencies that may not be directly visible in the classic astrological chart.
What Are Harmonics?;
Harmonics are the splitting of the zodiac into segments. Think about the 360 degree circle (the zodiac) and how it can be divided into different parts. Each harmonic corresponds to a particular division of the circle and reveals how the points on the chart are connected to each other based on that division.
For example:
The 2nd harmonic divides the zodiac in two, revealing relationships based on opposition aspects (180°).
The 3rd harmonic divides the circle into three parts, showing triangular aspects (120°).
The 4th harmonic divides the circle into four parts, bringing to light square faces (90°).
Harmonics can reveal aspects that are more difficult to discern in the traditional chart, offering a deeper understanding of our tendencies and potentials.
How the Harmonics Affect
Harmonics help us to understand how the planets “cooperate” with each other in terms of potential and hidden talents. Each of these harmonic charts shows us different things depending on the harmonic used.
For example:
2nd harmonic: Reveals how the opposing forces within us work. How do we balance our inner dichotomy?;
3rd harmonic: Associated with creativity and the ease with which we harmonize different parts of our personality. This harmonic shows how we enjoy life and express our talents.
4th harmonic: It shows the challenges and tensions in our lives, the obstacles we have to overcome and the hard efforts we have to make.
5th harmonic: It reveals creative talents and the ability to make new structures. It is the harmonic associated with innovation and ambition.
How We Calculate the Harmonics
Calculating a harmonic is done by using the degrees of each planet on the map and multiplying them by the number of the harmonic we want to calculate. Then, we analyze the position of the planet on the new map.
For example:
For the 2nd harmonic: Multiply the position of each planet by 2. If a planet is at 15° Aries, in the 2nd harmonic it will be at 30° Aries or 0° Taurus.
For the 3rd harmonic: Multiply the position of each planet by 3. If a planet is at 15° Aries, in the 3rd harmonic it will be at 45° Aries or 15° Taurus.

Applications of Harmonics
Harmonics are mainly used to better understand our psychological and spiritual powers. They can also help us to identify talents or inner challenges that may not be obvious at first glance in the classical chart. Harmonics are particularly useful for deepening our creativity, relationships and professional development.
Harmonics in astrology are a powerful tool to explore the hidden aspects of our personality and the deeper interactions of the planets in our chart. By studying these divisions of the zodiac, we can gain a more complete understanding of our potential, challenges and talents.
