Day 4: Counterbalance (Stop “Thumb Clamping”)

Watch (2 minutes)

Bill Kanengiser: On Left Hand Efficiency

What to listen for: how stability comes from support and counterbalance, not left-hand gripping.

‍

Do This Today (10–12 minutes)

1) Set the “stable guitar” position

Use the setup from the clip:

• the guitar feels supported
• you’re not “holding it up” with your fretting arm

2) Run the thumb clamp test

Form one barre (full or mini-barre is fine), then:

• Clamp the thumb for 10 seconds
  Notice where tension appears (thumb, forearm, shoulder, jaw).
• Then reduce thumb pressure for 10 seconds
  Keep the chord speaking, but aim for “just enough.”

3) Alternate for 6 cycles

Do 6 cycles of:

• 10 sec “too much”
• 10 sec “just enough”

(This trains awareness + control, not strength.)

‍

Success Check

You’re winning today if:

• the barre starts to feel like balance, not squeezing
• and “just enough” thumb pressure is easier to find on purpose

‍

Common Mistake to Avoid

Trying to remove the thumb entirely. The goal is less unnecessary thumb, not “no thumb.”
