The Easy Keyboard Library: Essential Chord Dictionary is full of simple chord diagrams, allowing you to easily find the right notes for each chord and play them in any inversion.
The chords in this book are transposed for every note of the scale and pictured in easy-to-read diagrams. Each chord is shown in a playable inversion, but the notes in the diagram can be played in any inversion to create the same chord. Using note-tabs at the end of the page, it makes chord location very easy indeed.
