## Where should I start with the upward reach?
The curriculum places The Full Chord before this module. Review those topics if they are unfamiliar. The first lesson is “Thumb Position Intonation”: Pure fifths and the high fingerboard. The order is a study guide, not proof that every learner needs the same pace.

## How long is the the upward reach module?
The 5 listed lessons total approximately 66 minutes of material. That estimate describes lesson content, not the practice time needed to become comfortable with thumb position mastery. Revisit one task at a time and use feedback from a teacher where physical technique is involved.
