Jimi Hendrix
Jimi Hendrix redefined the role of the electric guitar in a band context. He was not just a lead guitarist or a rhythm guitarist - he was both simultaneously, using chord partials, double stops, and melody in a way that made his three-piece sound full enough to not need a second guitarist. His theory vocabulary was deep without being academic, and it produced a completely original approach to the instrument that shaped every blues-rock guitarist who came after him.
Start with E minor pentatonic
Hendrix's blues foundation. He tuned down to E♭ but the shapes and thinking are all in E.
The E♭ tuning
Like SRV after him, Hendrix tuned a half step down to E♭ standard. The reasons are practical and sonic: the slightly lower tension makes bends easier and the tone slightly warmer and fuller. But the shapes remain the same. His E minor pentatonic box looks and feels identical to standard tuning - the notes are just all a half step lower in pitch.
When learning from Hendrix, think in standard tuning shapes. The theory concepts transfer directly. The half step down is a global transposition, not a structural change to how the scales relate to each other.
The major-minor blend: the defining move
Hendrix is the source of the major-minor pentatonic blend that SRV and John Mayer both inherited. The technique is his invention in the rock context, and no one executed it with more fluency or emotional naturalness. The move works like this: over a dominant or major chord, he plays phrases from both the minor and major pentatonic, switching between them within a single bar.
The critical note is the 3rd. E minor pentatonic has G (the minor 3rd). E major pentatonic has G# (the major 3rd). One semitone separates them. Hendrix moved between these two notes constantly - sometimes bending from G up to G#, sometimes playing G# directly, sometimes letting G create tension against an E major chord and then resolving it by lifting the bend to G#. The emotional content of a phrase changed completely depending on which 3rd he emphasized.
The two 3rds: tension vs resolution
One semitone. The entire emotional range of Hendrix's lead vocabulary lives in the distance between these two notes.
Chord-melody integration: the most important concept
The defining structural feature of Hendrix's playing is that he did not separate rhythm and lead. He played both simultaneously. A Hendrix solo passage often contains fragments of chords - not full strummed chords, but two or three notes from a chord played together - interspersed with single-note melodic lines. The result is that his guitar sounds harmonically complete without any other chordal instrument filling the space.
The mechanism is chord tones played in pairs. When the E chord is playing, he might play the root (E) and the 5th (B) together as a double stop - two notes that define the chord's stability. Then he moves to a melodic single-note phrase that outlines the same chord from within the pentatonic. The listener hears the chord, then hears the melody inside the chord, then hears them blended again.
How chord-melody integration works
A Dorian: minor with character
Hendrix used Dorian's raised 6th for brighter minor passages, particularly over slower, more expansive chord vamps.
Dorian and natural minor for extended passages
On longer, more melodically developed passages, Hendrix moved beyond pentatonic into full seven-note scales. Dorian was natural for his minor key playing - the raised 6th gave him an extra targeting note for chord changes and created the brightness he needed when the pentatonic felt too limited. Natural minor gave him the darker, heavier quality when the song called for it.
He did not use these scales systematically. He moved in and out of them by feel, using the pentatonic as his base and the extra scale tones as additions when a phrase needed more harmonic specificity. The 2nd and 6th of Dorian, in particular, allowed him to connect chord tones more smoothly than the pentatonic alone allowed - using them as passing tones between the structural pentatonic notes.
Wah pedal as a pitch-following tool
Hendrix's wah pedal was not just an effect - it was a harmonic amplifier. The wah filters the frequency content of the guitar signal, boosting certain frequencies while cutting others. When he swept the pedal in sync with his melodic phrases, specific notes became dramatically louder and more present while others receded. The effect is that some notes feel more important than others - the wah is making a mix decision in real time.
In theory terms, he was using the wah to emphasize chord tones. When a phrase moved through the pentatonic and landed on the root or the 5th, sweeping the wah toward the open position brightened those landing notes and made them ring out clearly. The non-chord tones - the passing notes - were often played with the wah in a different position, making them softer and more recessive. The pedal was reinforcing his phrase structure acoustically.
Playing over changes at full speed
Despite the rhythmic and textural complexity of his playing, Hendrix followed chord changes precisely. His phrase targets shifted with each chord. Over the I chord, he emphasized the root and major 3rd. Over the IV chord, he shifted his landing notes to emphasize the root of that chord. Over the V chord, he reached for the leading tone that pulls back to the I.
He achieved this by knowing the chord tones of every chord in a 12-bar blues without thinking about it. That knowledge was so internalized that it directed his note choices automatically. The lesson is not to think about theory while playing - it is to practice the theory so deeply that it becomes reflexive. Hendrix's playing sounds free and spontaneous because the harmonic knowledge underneath it was absolute.
