We celebrate the O Moon (Full Moon) with drums with round skins. We bring our attention to circular movement with fire poi and fire staff. We are aware of cycles, seasons, spirals and rhythms. Time and space.

For the month of August all the Moon Days are on Wednesdays. Today is the first with a Noon No Moon lunch. Next week is the G Moon (First Quarter) dinner. Then there is a the O Moon (Full Moon) Drumming peaking at midnight. Finally is the D Moon (Last Quarter) breakfast. These meetings and meals take place when the moon is at the zenith, right above us.
In previous versions of the Chromatic Circle I have introduced depth as a way of portraying pitch of notes but I’ve found it cumbersome. In researching for the Great Sphere I have come across the work of Marysol Gonzallez Sterling and her Biosonic webpage. There I saw the musical spiral amongst other things and it struck me as the obvious answer.
Here is the current version of the Chromatic Scale Spiral 3D as at 2013-05-23. The Spiral will be part of the Great Sphere.
The Spiral is displaying the Harmonic Series here. You can get more details on the Harmonic Series at the Wikipedia page but briefly it is a series of pitches present in all notes and the physics foundation for Western harmonic structure.
Each note is another fraction along from the note before. If the low C pictured above is this first line (0-1) then the next C above that is the next line below (1/2). That’s an octave. The next note up is a 1/3 harmonic and lands on the G – the perfect fifth. The 1/4 gives an interval of a perfect fourth which brings us back to C. 1/5 makes a major third taking us to E, 1/6 is a minor third to get us to G and 1/7 is a subminor third to give us Bb. Next, the 1/8 gives us a supermajor second to get us back to C for the fourth time covering three octaves. And it doesn’t stop there.
Anyone with some musical theory knowledge will see that these notes make your standard chord. Although , the further along the series the less standard it is.
Here’s a cartoon the Reverend couldn’t resist introducing to the fourth dimension this morning.
1. Use red/blue 3D glasses. View one eye at a time to see two different pictures.
2. If ‘b4’ is green or blue you need to look through the blue lens to see the Before picture. ‘afte’ will then be red so you look through the red lens to see the After picture.
Ideally 4D pictures will have some 3D effect when viewed with both eyes. Unfortunately this one doesn’t.
As with most images floating around the web it’s hard to find who is the artist. If you can help leave a comment so we can give credit where credit is due.
Here’s another version. This time ‘b4’ is red. Let us know which you prefer.
