Soloing Over the Blues
Blues is the one idiom where five notes will last you a lifetime. That makes it tempting to call it easy. The opposite is true: because the note choice is so limited, everything you do with those notes is immediately audible.
- 12 bars
- 5 notes
- phrasing is everything
At which level
- Beginner to advanced
- Guitar, piano, harmonica, voice
In short
The form is your clock: twelve bars in three phrases of four. I7 for four bars, IV7 for two, back to I7 for two, then V7, IV7 and home. Knowing where you are in that cycle without counting is the first real skill, because every phrase you play means something different depending on which of the three four-bar units it lands in.
Almost everyone plays minor pentatonic over major and dominant chords, which means a flattened third rubbing against the major third in the chord. In any other idiom that is an error. In blues it is the idiom, and arguing about it misses what is actually happening: the blue note is a movement rather than a fixed pitch, bent and approached rather than placed.
How you practise it
Since every chord in a blues is a dominant seventh, nothing genuinely resolves, and the tension is constant rather than directional. That is why phrasing carries the whole thing: call and response between phrases, space between them, and repetition of a figure until it becomes a statement.
Where you run into this
- A solo that works with five notes because of how they are attacked
- A phrase repeated three times, which is the oldest blues structure there is
- A player who leaves two bars empty and gains the room
Our own examples
The pentatonic playable here over the form, so you can test the claim directly: play the same five notes evenly, then play them with space and attack, and hear which one sounds like blues.
