If you want to study the astrology of singing look to Mercury and Taurus. Mercury is air in the (Gemini) lungs, Taurus rules the throat. Scorpio (opposite Taurus) is also worth noting as it is power (ruled by Pluto) opposite, therefore a give and take/unit.
Voice aspects have always been a subject of interest, as I have Moon in Taurus, a Virgo stellium and Libra Mercury at Midheaven. I love to sing, and sounds directly influence my state/peace of mind. The most intelligent, interesting lecture in the world would have trouble sinking in if I had to listen to a whiney, grating voice throughout.
It is what it is…just one of my quirks.
Now onto the astrology of voice.
Clear voice: Sun, Mercury, Venus well aspected, on the angles
Deep voice: Saturn highly aspected (esp in women) afflictions to Mercury, Venus
Fluency: expressive dexterity corresponds with 7 degrees Capricorn/Pisces
Rumbling, course voice: afflictions to Scorpio; Saturn in hard aspect to Taurus/Libra or Venus, also in hard aspect to Mercury
Gifted: Venus or Mercury in Taurus, 2nd house; Air signs on cusp of 2nd
Melodious: Venus (Taurus/Libra) on the angles (esp with Mercury) and well aspected
Vocal control/tone: strongest at 16 degrees Taurus/Scorpio; 17 degrees Aries/Libra
Voice strain: Uranus or Saturn in hard aspect to Mercury, Venus, Taurus or Air signs
The larynx is said to build its power from the sexual nature of the Scorpio axis – the sex drive kicks in with the deepening of the male voice in puberty. For this reason hard aspects (restriction) of Taurus/Scorpio will manifest in a high pitched voice in men; a low voice in women.
Venus and Mercury strong with benefics can compensate for hard aspects to Taurus.
It is wise to remember that any contact is an exchange of energy a square or opposition can be stronger than a trine when solved – aka worked properly, honed to your highest expression of it.
