Dorian vs. Mixolydian: Which Mode Should You Use in a Blues Solo?

When it comes to soloing over blues, most guitarists start with the pentatonic scale — and rightly so. It’s powerful, expressive, and easy to play. But what if you’re ready to go deeper? What if you want your solos to sound more colorful, more intentional, and more musical?

That’s where Dorian and Mixolydian come in.

In this post, I’ll break down what these two modes actually are, how they sound, and when you should use them in a blues solo. I’ll also show you how I personally approach this in real-world playing — no theory gatekeeping, just practical tools for making music.

What Are Dorian and Mixolydian Modes?

Let’s strip away the jargon and keep it simple.

• Dorian mode is like a minor scale with a raised 6th.

• Mixolydian mode is like a major scale with a lowered 7th.

Here’s how they look in A (since we all love A blues):

A Dorian:

A – B – C – D – E – F# – G
➡️ Minor sound with a slightly brighter...

Ever hear a chord in a song that makes you go, “Whoa — where did that come from?” Chances are, you’ve just heard modal interchange in action.

In this post, I’m going to break down what modal interchange is, why it sounds so cool, and how you can start using it to spice up your own playing — whether you're writing, improvising, or arranging. No jargon, no gatekeeping. Just real-world musical tools.

What Is Modal Interchange (a.k.a. Borrowed Chords)?

Modal interchange is when you temporarily “borrow” chords from a parallel mode — that is, a mode with the same root note, but a different quality.

So if you’re in C major, you might borrow a chord from C minor, C Dorian, or C Phrygian — just for a moment — to add color and contrast.

These borrowed chords create unexpected emotional twists. They sound dramatic, rich, or mysterious — because they don’t belong in your key, yet they resolve beautifully when used well.
