This book is about a new 12 notes per octave tuning called Eagle 53. This tuning was designed to improve on, and replace, the standard Western tuning: 12 Tone Equal Temperament. Some notes are higher than usual and others are lower in varying degrees. Many chords and scales are more in tune and some new and exotic chords and scales occur as well. Eagle 53 tuning is suitable for pianos and MIDI keyboards that can be retuned with the right software and for guitars and other stringed and fretted instruments (which need refretting to accommodate the new tuning). This book describes how the author worked it out, the rationale and mathematics behind Eagle 53. Eagle 53 is a slightly tempered version of a just tuning, Eagle J.I. which looks like this:
1/1, 16/15, 9/8, 6/5, 5/4, 4/3, 7/5, 3/2, 8/5, 5/3, 9/5, 15/8, 2/1
The '53' refers to 53EDO (53 Equal Divisions of the Octave). Eagle 53 is a 12 note subset of 53EDO.

Most authentic book compilation on the Oregon Trail I ever read. The way the diaries are brought to life from over 170 years ago is a remarkable achievement. Top book of year so far for me for today June 01, 2024 review Candice
This author is a breathe of fresh air in a world of lies and coverups. He brings ancient writings and new science to bring light to mankind. In this amazing work, the well known plato stories from antiquity are now put alongside this new discovery of tablets from beginning of time. This is the most complete explanation of Atlantis every brought to the public. Shame on the governments of Egypt and the world for hiding WHO BUILT THE PHYRAMIDS OF GIZA AND THE SPHINX. Once I read this book I knew why they hid this knowledge. They don't want a population to know how great the world used to be compared to know.
Randomly stumbled upon this book and I am shocked that I haven’t heard about it before. It’s hands down the best story I’ve read in years. People need to read this book. It needs to be turned into a book. This story is just plain awsome. M
This soulful book of personal poetry brought me into the past and into the present---and into my heart.
Read the first book and this 2nd one did not disappoint! Loved every chapter. More please!
