Artistic Alchemy Draw like Da Vinci

Classical rules of composition are not magic. Just maths! Almost every artist, sculptor, architect and musician you liked - used or uses these rules. The Golden Mean, Divine Proportion, The Golden ratio, the Divine Section all describe the same thing, a mathematical technique to divide a canvas, marble block or musical stave into aesthetically pleasing compositional divisions. At the heart of this principle is a series of numbers called the Fibonacci series. The Fibonacci numbers can be used to describe harmonious spatial relationships found in nature including leaves, flowers, shells and human anatomy. The closer images adhere to the Fibonacci series the more natural and pleasing the relationships appear to the human eye. Spatial relationships that do not adhere to the series register as dissonant to the human mind. As an artist who  you can exploit these principals to your advantage. People see harmony within your work, but often they will be unable to describe why the work appeals to them so strongly. There are many websites dedicated to Fibonacci and the Divine Proportion, check them out then get drawing. Also check out other artists and the proportion of everyday items in your home. See how many of them conform to the Artistic Alchemy. Like a Dan Brown novel but with real treasure at the end!

In the diagrams the xpoints within the circle show the ideal point of compositional focus. You can also have secondary points of focus and subdivide areas into further golden boxes within boxes. Enjoy!
