Watch the C Blues Scale online guitar lesson by Brad Carlton from Guitar Lab: Big Blues & Beyond
The C blues scale 6th string root form in eighth position is used in this lesson as the tonal framework. Various size barres with the 1st finger are used to play the "low side" of the C blues scale. You then trill (hammer-on and pull-off combinations) the "high side" of the C blues scale. This will help you see the scale on the fingerboard, learn the note names and their respective scale degree labels, and technically you will strengthen your fretting hand.
