Watch the All Boxed Up online guitar lesson by Andrew Ford from Blues Bass Survival Guide

Now we have a shuffle groove using the box shape, ascending and descending, it is kind of a Stevie Ray uptempo groove where the A section plays a more traditional shuffle and the B section goes to a more open walking pattern. This one is written using 8th notes for notation simplicity but played as triplet figures where a quarter note is tied to an eighth note as indicated by the symbol in the left corner of the notation. It's in the key of A.
