Introduction

Pi (Π) is the ratio of a circle's circumference to its diameter. It has been represented by the Greek letter "Π" since the mid18th century.

This constant is approximately equal to 3.14159. The digits in the decimal representation of Pi appear to be random, although no proof of this supposed randomness has yet been discovered.

Pi is an irrational number, which means that it cannot be expressed exactly as a ratio of two integers, consequently, its decimal representation never ends and never repeats. Moreover, Pi is a transcendental number: a number that is not the root of any nonzero polynomial having rational coefficients.

For thousands of years, mathematicians have attempted to extend their understanding of Pi, sometimes by computing its value to a high degree of accuracy. Before the 15th century, mathematicians such as Archimedes and Liu Hui used geometrical techniques, based on polygons, to estimate the value of Pi. Starting around the 15th century, new algorithms based on infinite series revolutionized the computation of Pi, and were used by mathematicians including Madhava of Sangamagrama, Isaac Newton, Leonhard Euler, Carl Friedrich Gauss, and Srinivasa Ramanujan.

In the 20th century, mathematicians and computer scientists discovered new approaches that (when combined with increasing computational power) extended the decimal representation of Pi to over 10 trillion digits. Scientific applications generally require no more than 40 digits of Pi, so the primary motivation for these computations is the human desire to break records, but the extensive calculations involved have been used to test supercomputers and high-precision multiplication algorithms.

Because its definition relates to the circle, Pi is found in many formulae in trigonometry and geometry, especially those concerning circles, ellipses, or spheres. It is also found in formulae from other branches of science, such as cosmology, number theory, statistics, fractals, thermodynamics, mechanics, and electromagnetism. The ubiquitous nature of Pi makes it one of the most widely known mathematical constants, both inside and outside the scientific community.

Several books devoted to it have been published. Pi is also celebrated on march 14th (Pi Day 3/14).

"Lonesome Pi experiment" is a heuristic musical project built by one man ("lonesome") whose objective is to show that it is possible to create contemporary consistent music without experience in musical techniques. This trial is based on simple mathematical rules (nod to "Pi"), as repetition of sounds and sequences created using a computer. Lonesome Pi has already generated some "tracks", you will find excerpts on this website.

Lonesome Pi sets his approach on a rebellious sound slope both in music and lyrics. He hopes to develop, for those who find inspiration, musical creation with no other goal than his own birth, leaving commercial interests that distort the purity and power of sound.

It is possible to let our creative spirit guide us on the sounds that we really want to hear ... switch to "listening mode"! Our ears are directly connected to the brain by a complex neuronal circuit, it is called "auditory brain", we can make it more active and initiate a selective blocking of the pseudo-melodies that are imposed on us every day.
