This book is a sequel to The Eagle 53 Pianist and lists 2,999 jazz chords that occur in the Eagle 53 musical tuning. The jazz chords listed in this book are not as strong as the lush chords in the Pianist book but are perfectly usable in the right context. Many of the chords are exotic, they contain intervals containing 7s or multiples of 7 which you won’t find in the regular Western tuning: 12 Tone Equal Temperament. There is a chapter on composition and chord progressions in Eagle 53. The chords in this book are intended for pianos or keyboards tuned to the Eagle 53 tuning where some notes are higher than usual and others are lower.
