This book contains diagrams of 940 Lush chords that are playable on guitars fretted for the Eagle 53 musical tuning. A lush chord is both strong and clearly rooted. 65 clearly rooted scales and 31 other scales are also described. There is some mathematical background and a chapter on composing. A sequel to this book will contain diagrams of chords that are not lush but are very versatile in the right context. The sequel is called The Eagle 53 Guitarist Jazz Chords. Be warned that the Eagle 53 tuning cannot be implemented on regular guitars, a special fret arrangement is required.
