The 12-bar blues is a classic structure that serves as a foundation for countless songs across various genres. One of the key elements that give the blues its unique flavor is the use of 7th chords. These chords add tension and resolution, enriching the emotional depth of your music. In this guide, we’ll explore three diverse examples of using 7th chords in a 12-bar blues context, helping you incorporate them into your own songwriting.
