E Blues Scale in Practice
The E Blues Scale uses the key signature of 4 sharps (F#, C#, G#, D#). E major has four sharps and a powerful, resonant sound particularly suited to guitar. It is one of the most common keys in rock and blues music. On guitar, E positions offer open-string resonance for fingering positions for this scale.
The blues scale adds the flat 5th (blue note) to the minor pentatonic scale, creating the characteristic dissonant tension central to blues, jazz, and rock music.
