| ASPECT | ANGLE | HARMONIC | INTERVAL | FIELD QUALITY |
|---|---|---|---|---|
| Conjunction | 0° | 1st | Unison | Fusion. The two energies merge. Amplification of both — for better or worse depending on the planets. |
| Sextile | 60° | 6th | Major 3rd | Opportunity that requires action. The door opens; you still have to walk through. |
| Square | 90° | 4th | Minor 7th | Friction. The most productive dissonance. Growth under pressure. The aspect of becoming. |
| Trine | 120° | 3rd | Perfect 5th | Flow without friction. The most harmonious major aspect. Sometimes too easy — the gift that goes unused. |
| Opposition | 180° | 2nd | Octave | The mirror. What you project onto others. Tension that resolves when you own both poles. |
| Quincunx | 150° | — | Major 7th | Adjustment. Incongruent energies that require ongoing recalibration. Never fully resolves. The aspect of perpetual refinement. |
