For example, in the top plant in the pictureabove, we have **3** clockwise rotations before we meet a leaf directly abovethe first, passing **5** leaves on the way. If we go anti-clockwise, we needonly **2** turns. Notice that 2, 3 and 5 are consecutive Fibonacci numbers.

For the lower plant in the picture, we have **5** clockwise rotations passing**8** leaves, or just **3** rotations in the anti-clockwisedirection. This time 3, 5 and 8 are consecutive numbers in the Fibonacci sequence.

The next diagram shows that we candraw a spiral by putting together quarter circles, one in each new square. This is aspiral (the **Fibonacci Spiral**). A similar curve to this occurs in nature as theshape of a snail shell or some sea shells. Whereas the Fibonacci Rectangles spiralincreases in size by a factor of Phi (1.618..) in a (i.e. a pointa further quarter of a turn round the curve is 1.618... times as far from the centre, andthis applies to points on the curve), the Nautilus spiral curve takes a before points move a factor of 1.618... from the centre.

These spiral shapes are called Equiangular or Logarithmic spirals.

## What is the Fibonacci Sequence? History and Explanation

The natural scale is the scale used by me for the chakras, and not the Western diatonicscale per se. A long time ago the Highland bagpipe and other traditional instruments had afundamental "A" of 432Hz, but this was increased to 440Hz with advent of the"standard" of 440, followed later by further increases in pitch to get pipebands to perform with brass bands and orchestras. This Westernisation of folk instrumentsdestroyed their inherent relationships with natural phenomena, and consequent loss ofspiritual synergy with nature.
