Watch the Thumb Stumbles online guitar lesson by Ton van Bergeijk from Fingerstyle Blues & Boogie Guidebook

The circle of guitar friends I grew up with in the late 60's and early 70's all referred to Blind Blake's thumb patterns as "thumb stumbles", so any variety of the classical "rest stroke" in my mind is a "thumb stumble". I tend to apply these types of thumbing to several different kinds of picking patterns.
