For those following the development of the Great Sphere and the Chromatic Spiral here is the latest development.
What happens when Key dictates Rhythm? What if a Tone equals a Crotchet and a Semitone equals a Quaver?
To visualize this the piano keys are set out in a circle like a clock. Starting at 12 o’clock and playing only the white notes, Section 1 shows the major scale and its clockwise (the Standard Bell Pattern) and anti-clockwise rhythms.
Section 2 starts at 9 o’clock revealing the minor scale and rhythms (Ashanti first).
Section 3 and 4 explore the Pentatonic scales and rhythms by playing the black notes from 6 o’clock (Major Pentatonic scale and Son Clave rhythm first) and 3 o’clock (Minor Pentatonic scale).
Section 5 returns to 12 o’clock and tries to make sense of everything we’ve heard and mashes it all together.

Here is a new way to view the chromatic spiral. I have added circles of colour corresponding to the notes played to enhance the idea of the colour wheel representing the pitch circle. These large circles overlap and blend. The idea is to associate these blended colours we see with the interval of the two notes we hear.
I am not sure if this works. When we have three notes from opposite sides the three opposing colours blend to white. White is the presence of all colours therefore it should be the sound of not only all notes but all frequencies in between.
However, one experiment remains and that is to use the primary colours in the positions of the tonic, third and fifth. Although, as I type this I cannot imagine this working.
Pythagoras is known as the Father of Music formalizing a system built on ratios and came up with the 7 notes of the octave. Over time we have filled in the gaps with the ‘black keys’. When played separately these five notes form the Pentatonic Scale which is found all over the world in largely indigenous music. Bobby McFerrin explains the Pentatonic scale best here: http://www.ted.com/talks/bobby_mcferrin_hacks_your_brain_with_music
The 12 music notes (including sharps and flats) are displayed like a clock. As the notes rise in pitch they move around the clock. When they are back at 12 they are they same note only up an octave. (At this stage the soundwave is twice as fast.) This video plays with this idea.
