Dave is a musician who clearly loves guitars. He’s got an impressive collection of guitars and basses he uses to create music. But whatever beat he’s playing to, he knows the importance of always staying upbeat, which, in itself, can raise the emotional tone of the entire environment. Understanding emotions and their effects is possible with The Emotional Tone Scale course from The Scientology Handbook.

The Emotional Tone Scale is one of 19 free Scientology online courses based on principles from The Scientology Handbook.
