Also called: Angle of harmony · Practical angle · Upper thumb angle · Angle of dexterity

Where on the hand: On the same radial edge of the hand as the angle of rhythm but higher, at the point where the thumb itself joins the palm.

What it looks like: A pronounced bump interrupting the line of the hand's edge at the thumb's join, again read from the silhouette. The larger the bump, the stronger the reading.

Read as manual competence and practical timing: the person handles objects and tools well, judges when to act, gets things done efficiently, and prefers a workable solution to an elegant one. Sources describe its owners as neat-handed and realistic, and note that it very often accompanies the angle of rhythm.
