The book and worksheets show a simple and unique method of quickly determining the notes to any chord by applying a few simple rules. Notes are in the most practical form (usually 3 or 4 notes), even for the most complex chords. A small chart is included. If needed, the chart leads one through the process and names the notes. This book can be useful when playing any instrument that uses chords. There is no complicated theory. Only the stuff you need to look at a chord and play the notes.
