# Living in the Upper Register, Double bass

Extended thumb position and the extreme high range

The very top of the bass fingerboard is a frontier, the string is short, the response is immediate, and the player who masters it gains access to a register that sounds like no other instrument on earth.

Advanced · 4 lessons · approximately 96 minutes of material (not a mastery deadline).

## Where should I start with living in the upper register?
The curriculum places Harmonics before this module. Review those topics if they are unfamiliar. The first lesson is “Extended Thumb Position”: Moving beyond the familiar into the extreme upper fingerboard. The order is a study guide, not proof that every learner needs the same pace.

## How long is the living in the upper register module?
The 4 listed lessons total approximately 96 minutes of material. That estimate describes lesson content, not the practice time needed to become comfortable with extended thumb position and the extreme high range. Revisit one task at a time and use feedback from a teacher where physical technique is involved.
