Chart data for astrologers
The one-to-one reading
Thirty seconds is only the overture.
A song can tell you what your chart sounds like. A reading tells you what it means: one to one, with an astrologer who has your whole chart in front of them.
Mention your Skysong when you book and it will be playing when you start.
What a reading opens up
- The whole chart, not the highlightsEvery planet, house and aspect, read together as one person.
- What the sky is doing to it nowThe transits moving over your chart this year, and what they are asking of you.
- Your questionsWork, love, timing, direction. You bring them; the chart answers in its own terms.
The tuning
room
Tap anything here to hear it. This is the whole instrument, so an astrologer can check our working.
Every planet has its own voice
The planet decides the instrument and how high it sits. Its sign decides when it plays; its degree decides which note of the chord it lands on.
Every aspect is an interval
In 1619 Kepler showed that the aspects and the musical consonances come from the same divisions of a circle. Skysong uses his ratios. When two planets are in aspect, the second answers the first at that interval. Soft aspects are tuned pure and ring still. Hard aspects are tuned a hair wide, so they shimmer.
- Your Sun sets the keyThe twelve signs walk the circle of fifths from Aries at C. A Capricorn Sun plays in E♭, a Leo Sun in E.
- Your Moon sets the modeFire is bright major. Earth is major, softened. Air is major, lifted. Water is minor, tender and deep.
- Your rising sign starts the discTwelve bars, one for each sign, beginning where your chart begins. An empty sign is answered by its ruling planet.
- Venus sets the stepVenus in earth or water turns the song into a waltz. In fire or air it walks in four.
Good
to know
Do I need to believe in astrology to enjoy this?
No. The disc is built from where the Sun, Moon and planets really were when you were born, worked out with standard astronomical data. What that means is where astrology, and a reading, come in.
What if I don't know my birth time?
Tick "I don't know my birth time". Your song is made for midday, the rising sign and houses are left out, and the Moon's aspects rest because the Moon moves about thirteen degrees in a day. Everything else is accurate.
Is my birth data saved?
Your chart is calculated in your own browser. Nothing is sent anywhere unless you enter your email for your liner notes, which sends your email and a summary of your chart so the notes can reach you.
How accurate is the chart?
Positions use the tropical zodiac and are accurate to within about a minute of arc. Houses are Placidus, falling back to whole sign near the poles. The node is the true node. Daylight saving and historical time zones come from the standard time-zone database. Open "Chart data for astrologers" under your song to compare with your own software.
Will two people ever get the same song?
Only if they were born within minutes of each other in the same place. The key, mode, tempo, voices and every note come from the chart, so twins share most of a song and everyone else gets their own.
Now play one for someone you love.
A partner, a child, a friend with a birthday coming. All you need is when and where they arrived.
