Pig Ankle Rag – Version 2 – Advanced! As a follow up to the basic version of the tune, here is a great version with variations up the neck, embellishment of the melody and loads of blue notes and chromatic passages, which really suits the style. We’re in the key of D (standard tuning-capo 2), playing in a shuffle feel, and I’d suggest you check out the basic version here first, if you haven’t already.
