The Tone Scale shows the successive emotional tones a person can experience. By tone is meant the momentary or continuing emotional state of a person. Every person has a chronic or habitual tone. He or she moves up or down the Tone Scale as he experiences success or failure. These are temporary, or acute, tone levels. A primary goal of Scientology is to raise a person’s chronic position on the Tone Scale. Learn how to use this scale to predict and understand human behavior through the booklet The Emotional Tone Scale and its accompanying course.
