Otis Rush's "Double Trouble" is a blues masterpiece, instantly recognizable for its haunting melody and powerful, emotive chord progression. For aspiring blues guitarists, learning this song is a rite of passage, demanding a strong understanding of blues scales, bending techniques, and rhythmic feel. This guide will break down the chords and offer insights into the song's structure, helping you navigate this challenging yet rewarding piece.
Understanding the Basic Chords
The core of "Double Trouble" relies on a relatively simple, yet highly effective, set of chords within the key of E. However, Rush's mastery lies in his phrasing, bending, and vibrato, adding layers of complexity and emotion that transcend the basic chord structure.
- E7: The dominant seventh chord, acting as the foundation of many blues songs. This is often the root chord, providing a solid, grounding sound.
- A7: Another dominant seventh, creating tension and moving the progression forward.
- B7: Adding a further layer of tension, leading back to the resolution on E7.
- E: The tonic chord, providing a sense of resolution and stability. Often used as a variation on E7, especially in the verses.
Chord Progression and Variations
The most common progression used in "Double Trouble" follows this basic pattern:
E7 - A7 - B7 - E7 (or E)
This simple sequence is repeated throughout the song, offering a framework for improvisation and embellishment. However, Rush doesn't always strictly adhere to this progression. He often introduces subtle variations, adding passing chords, or altering the rhythm to create a more dynamic and nuanced feel. These subtle changes are what give the song its unique character and keep it from sounding repetitive.
Beyond the Basic Chords: Adding Nuance
The true magic of "Double Trouble" isn't just in the chords themselves, but in how Rush plays them. He uses techniques like:
- Bending: Bending notes significantly alters the tone and feel, adding emotion and expressiveness. This is crucial for capturing the essence of the song.
- Vibrato: A subtle vibrato adds warmth and depth to the notes, enhancing the overall emotional impact.
- Hammer-ons and Pull-offs: These techniques create a dynamic interplay between notes, adding rhythmic interest.
- Slides: Smooth transitions between notes enhance the fluidity of the melody.
