Improvisation — blues in E
One scale - the E minor pentatonic, position 1 - covers the whole E7-A7-B7 blues grid. There's no need to switch on every chord: the blues tolerates the same scale running over all three chords, because it dodges the notes that would create a real clash. Everything relates to the E root. The grid is given at 80 BPM, slow enough to leave room for silence. The goal isn't to fill the twelve bars with notes, but to learn to build short phrases that answer the chord changes.
Tips
Start by playing only the note E, in rhythm, especially as the chord moves to A7 or B7: that's the reference that keeps you from getting lost.
Once that anchor is solid, add one or two neighbouring notes, then alternate short phrases with silence.
Listen to what changes under your fingers as the chord moves: the same note doesn't sound the same over E7 and over B7.
Understanding this type of exercise
One scale for the whole grid
The E minor pentatonic (position 1) works over E7, A7 and B7 without changing: everything relates to the same root, E.
Practical tips and common mistakes
- Start by playing only the note E, in rhythm, especially when the chord moves to A7 or B7: that's the reference that keeps you from getting lost.
- Once that's solid, add one or two neighbouring notes, then alternate short phrases and silences (call and response with the grid).
- Over a shuffle blues, lock your phrases to the bounce, not to straight eighth notes.
- The "blue note" (a chromatic passing note) comes later, once the pentatonic is fluent.
