I wanted to take a quick look at the more modern style of blues vs the older, more traditional style. Now, it should be said you can’t have the modern blues style without playing something from the traditional era so to speak. Everything is connected in someway. Modern blues has borrowed alot from other styles like Jazz, just look at Robben Ford for that. SRV took a lot from Jimi Hendrix. The original blues players were largely self taught (and many of them illiterate), and one of the easiest ways to create different chords was to tune the guitar to an open chord, such as G major or E major, and then use a metal or glass slide (a pocket knife or bottle neck) to change chords.
Blues guitar can take many forms, which means that learning how to get the blues sound is an evolving process. However, by identifying specific techniques, notes, and patterns to follow, you can begin finding your own blues sound.
What defines a blues song is the way chords are put together, or the chord progression. Although there’s no such thing as a blues chord, if you put certain chords together in a certain way, you can definitely create a blues chord progression. The most common blues progression is the 12 bar blues. This has evolved into more complex variations, major and minor ect. There is also now a lot more of a blue/rock combination common in todays blues acts.
Lets take a look at some of the pioneers
