Watch the Root 56: Shuffle online guitar lesson by Corey Congilio from 50 Blues Rhythms You MUST Know

This first batch of grooves revolves around what I consider to be the most basic of blues rhythms.

If you've played any blues at all, you've probably used these first few rhythms. Many of the rhythms we're going to play revolve around the common 12 bar blues. The 12 bar blues is a musical "form" or "song structure" that consists of 12 measures. The chords in this first example consist of the open (or first position) root-V chords. You'll also be incorporating the root-VI shape. These examples can be traced to guitarists like Chuck Berry, Elmore James, and as far back as Robert Johnson. I believe these rhythms were invented to mimic the stride piano styles of the 30's, 40's and 50's.

Even though this may seem simple, we need to start here to develop a trend throughout the course. Even if you know this progression, watch the video as it will set up future examples.
