thanks mirage29, i'm kinda new to astrology but i concentrate mostly on musical subjects. That way i can rely on my own musical experience and intuition and learn the language of the sky at the same time :-)There's some sad news since i first posted this topic. Apparently Avicii died after he cut his wrists using a shard of glass from a wine bottle, which is quite symbolic i guess for someone with an alcohol problem. It also points to the Mars-Pluto conjunction i think.
But to me the placement of Icarus in Avicii's chart is perhaps the most telling. The Venus-Icarus conjunction seems to capture half the story of Avicii's downfall if you ask me.
The Golden Aspects are really fascinating to me. I used them to find out more about the nine Muse asteroids, and a few other related ones like Harmonia, Sappho and Apollo.
You mention Harmonia yourself, so here's my take on that wonderful asteroid: i get the impression from the golden aspect research that Harmony can specifically point to 'unusual' kinds of Harmony. Examples i've found of a strong Harmonia 'influence' would be the Scottish percussionist Evelyn Glennie, a professional musician who is technically deaf, or John Cage, who composed strange things like a few minutes of silence. Or Grace Jones, who has an unusually low voice and unusual looks (kind of androgynous but not really). I actually have a strong (geocentric) Harmonia myself, which is spot on, because i compose music using non-standard tunings (the technical term is xenharmonic). Heliocentrically, my main muse is Sappho, which means that i'm a sucker for pretty women with great voices. I've actually done quite a few musical projects that were inspired by Sappho :-)
If anyone is interested in their strongest muse using the golden aspect method, just let me know and i'll calculate it for you.
