Basic Theory - Mixolydian Over Dominant Seventh
Mixolydian works in blues because it includes all the tones that make up a dominant seventh chord (and its natural extensions) - the chord type used in most major/dominant blues progressions (e.g. A7, D7, E7).
So we have the 1, 3, 5 and ♭7 intervals that make up a dominant seventh chord, making Mixolydian a natural dominant scale.
Why am I telling you this? Because these will be our strongest target notes for our phrases and licks, as they connect directly to the backing chords.
The other scale intervals - the 2, 4 and 6 - can be thought of as "colour tones" that we'll use to flesh out our phrases, like "connect the dots".
Think of using the tones in this way and you'll never get lost when improvising!
Mixolydian Scale Patterns for Blues
As there are three chords in a standard blues progression (sometimes referred to as 1, 4, 5), we'll need a different Mixolydian pattern for each chord. Unlike scales such as minor pentatonic, a single Mixolydian scale won't cover all the chords. But it's not as challenging as it sounds!
Use the 1 chord pattern as the reference for the key you're playing in. So if you're in the key of A, position the 1 of the 1 chord pattern on A (5th fret). If you're playing in C, position the 1 of the 1 chord pattern on... C.
Once you establish that 1 chord position, the 4 and 5 chord patterns can be made to fall into the same position.
Use the tabs below to switch between the 1, 4 and 5 chord Mixolydian patterns.
Once you're comfortable with changing between those patterns (take your time!), we can extend them to reach higher places on the neck - good for taking your licks up a level. See how the patterns from earlier (greyed out below) connect to the new three-notes-per-string patterns...
Dominant 7th Tones
As covered in the video, it's good to know where these strong, dominant 7th chord tones exist within the Mixolydian pattern. This is so you can confidently target those tones in your phrases and also use them as arpeggios to provide the "skeleton" for your phrases (examples later).
Spend time learning where these chord tones lie in the 1, 4 and 5 patterns...
Phrasing Ideas & Examples
Use the following process to build up your improvisation skills...
- Start by playing just the chord tones over each chord, either one per chord or arpeggiating each chord. This will get you used to targeting these tones as the chord changes, keeping your melody connected to the backing music.
- Build simple three/four note phrases over each chord that land on one of the chord tones. Think of it like "connect the dots", the "dots" being the chord tones!
- Try using three/four note arpeggios as "lead-ins" to your phrases, or to break up your phrases, essentially outlining the chord within the phrase.
- Practice linking phrases together through the chord changes. Again, the chord tone positions will help you move into place for the current chord.
- Gradually add in techniques such as bends, slides, hammer-ons and pull-offs to really squeeze the colour and emotion out of the scale. We'll focus on these techniques in a separate lesson.
In the video, we focused on the 1 chord. But you can also apply the following phrasing ideas to the 4 and 5 chords. Below are the tabs from the lesson examples (key of B♭)...
Targeting Chord Tones
Practice targeting chord tones (the 1, 3, 5 and b7) within the scale pattern. Build simple phrases that resolve to each of these target notes.
The chord tones can also be arpeggiated (played one after the other) as a lead-in to your phrases. So we're basically outlining the chord we're playing over and then "fleshing out" those chords using the colour tones from the scale...
Minor 3rd to Major 3rd
We know that the major 3rd is a strong target note. But it sounds even better if we move to it from a minor 3rd, one fret down. For example, here's how we might visualise the minor 3rd in relation to the 1 chord pattern...
Here, I bend from the minor to major 3rd on the 1st string...
Another example, using a hammer-on...
Across the whole pattern...
4 to 3
The 4 of the scale naturally resolves down to the 3rd...
Double stops involve playing two notes together. We're still using the scale pattern, but picking two notes instead of one. Examples...
Practice these phrasing techniques on the 4 and 5 chord positions using the patterns from earlier. Hours of practice right there! But you can use the below backing tracks to keep it fun...
Here I've selected some quality blues backing tracks, courtesy of Cliff Smith, to make your practice more fun and engaging.
Each track follows the standard 12 bar blues formula.
For each key, there's a slow and faster tempo. Obviously start with the slow track and then move to the faster one as your confidence improves. Select your chosen key using the tabs...
Time for a cold one, I think! Thank you for your time and patience. Hopefully, you'll have plenty to play with for weeks, months and years to come.
Blues really is a great style of music to develop your soloing skills, because it's relatively simple in form. With Mixolydian under your fingers, you'll be able to create those sweet, spine tingling solos that express what no words ever can, and that's what music is truly about. Live, breathe and enjoy it!
