Blues Guitar Soloing
Almost every blues player learns to solo the same way: one minor pentatonic box, parked in one spot, run over all twelve bars. It works — for a while. Then you notice the pros sound like they’re following the chords while you’re playing the same handful of notes over everything, and you can’t work out what they’re doing differently.
What they’re doing is playing the changes — letting the solo move when the chord moves. It’s not a harder scale or a faster lick; it’s a few well-placed notes that lock onto each chord as it goes by. Once you see where those notes are, your pentatonic box stops being a cage and becomes a home base you leave and return to.
This tool shows you exactly that. It starts from the minor pentatonic shell you already know, then adds the notes that outline each chord — the I, the IV, the V — one step at a time, so you can hear your solo start to follow the progression. It’s free, nothing to install, and it works on your phone right next to the guitar.
The Blues Chord Book
Open chords, moveable stabs & the 12-bar forms.
How to use it
Pick a blues — standard 12-bar or minor — and the tool builds your soloing vocabulary in steps. It starts with the minor pentatonic shell, the box you already know, then layers in the “outlining” notes that target each chord in turn: the I, the IV and the V. Follow the steps and watch how a couple of added notes per chord turn a static box into a line that moves with the progression. Then take the same idea to your own playing over a backing track.
Why one box isn’t enough
The minor pentatonic is the right place to start and the wrong place to stop. Played over a whole 12-bar, it sits on top of the chords instead of inside them — which is why it can sound the same bar after bar. The fix isn’t abandoning the box; it’s adding the few chord tones that change as the chords change. Outline the I chord, then catch the third of the IV when it arrives, then nail the V — and suddenly the same box sounds like you’re spelling out the form. That’s the whole secret behind “playing the changes,” and it’s far simpler than it sounds.
What’s inside
Both the standard 12-bar and the minor blues, each broken into clear steps — from the pentatonic shell, to outlining the I chord, the IV and the V — with every outlining note shown on the neck so you can see exactly which note locks onto which chord, and why.
Who it’s for
Blues players stuck in one box who want their solos to move. Anyone who can run the pentatonic but can’t yet hear the chords in their lines. Guitarists ready to take the step from “playing a scale over the blues” to actually playing the blues.
This tool shows you the idea. Blues Soloing Maps: Playing the Changes is the full method — the maps and lines that take you from one pentatonic box to soloing through an entire blues, chord by chord.
