LucyTuning is a musical microtuning system derived from Pi and the writings of John "Longitude" Harrison. This system enables users to modulate and transpose using any scales or keys that they may choose.

Beyond the scales, tunings and modes of Western music (Lydian, Ionian, Mixolydian, Dorian, Aeolian, Phrygian, or Locrian ....), with LucyTuning, it is possible to emulate Japanese, Indonesian, Chinese, Indian, Arabic (makam) and any conceivable tuning system.

Logic Studio (Pro 9 and 9.1.0 and Logic Pro X) now include one LucyTuning which Apple have called "harrisonj", or "John Harrison (1775), almost 3/10-comma, third = 1200/pi".
Download 53 more LucyTunings for Logic 7, 8, Pro 9, Logic Studio and Logic Pro X (which are currently free for non-commercial use). LucyTuning tables are also available there for Cubase, Melodyne and other DAW's.

Western harmonic structure may be used with this very specific meantone tuning system. This enables users to progress beyond the limitations of twelve note equal temperament (12edo), and produce music with controlled and predetermined levels of consonance or dissonance.
ScaleCoding now available free for Bento 4 on your Apple devices including index of con/dissonance.

It seems that the traditional scientific mapping of harmonics may be a simplistic paradigm of a more profound and fundamental underlying reality. Instead of considering audio as a static two dimensional mapping (e.g. sine wave), there appears to be a dynamic pattern which could consist of more dimensions, than revealed by the standard model for the physics and mathematics of acoustics. Many musical academics will tell you that for all practical purposes LucyTuning is identical to 88 equal interval per octave or 3/10 comma meantone tuning. These detractors fail to appreciate that musical "harmonics" should beat, and that the integer frequency ratios are merely "landmarks" which contribute to that beating. Using π (pi) as the generator for musical tunings, departs from all other microtuning systems, and resolves many of the obvious paradoxes in the traditional view of the mathematics of musical tuning.

For those who prefer their essential microtonal reading and reference in hard copy, the latest (Jan 2012) edition of Pitch, Pi, and Other Musical Paradoxes - A Practical Guide to Natural Microtonality - MusicAsEasyAsPi which was first published in 1986 is now back in print again and selling at the usual price of £220 UK Pounds, €265 Euros, or $350 US Dollars. Email to to place your order which will be shipped from London, UK.

LucyTuned Lullabies (from around the world) demonstrate how the music sounds by using instrumental renditions of traditional melodies, and generates low frequency beating which encourages relaxation and sleep in babies and other humans of all ages. Listen to examples and view a Flash cartoon.

This site contains analyses of frequency (Hertz), beats per minute (BPM), colours of the spectrum (R,G,B), and how these relate to the speed of light in a vacuum. MIDI tuning dump specifications, pitchbend data, guitar fretting positions and detailed instructions for LucyTuning samples are also given.
