Overview
Harmonics reveal hidden patterns in the natal chart by multiplying all planet positions by a harmonic number. Each harmonic emphasizes different aspects of the chart — relationships (H5, H7), career (H10), spiritual patterns (H9/Navamsa), and more. AstroWay calculates harmonics instantly in the browser with full aspect analysis for each harmonic.
