If you like heavy metal, jazz, or exotic sounding music you are likely going to be a fan of Phrygian mode. The note intervals and qualities have a great mix of dissonance, but not too much.
When playing this scale on guitar it allows you to make some unique solos and riffs, as long as you stay grounded in proper resolution and consonance.
What is the Phrygian mode?
A mode is simply another term for a scale that starts on a particular degree.
The most common is the Ionian or plain major scale.
The Phrygian mode starts on the 3rd scale degree, so E Phrygian has the notes E F G A B C D.
Now these are the same notes as the C Ionian C D E F G A B. Even though they have the same notes, they now have different intervals.
Play around with each scale on your guitar and you will see the entire vibe is more foreign or exotic sounding.
Now because these new minor intervals cause some dissonance, the Phrygian is often used along with other modes. It isn't as limited as the Locrian, but it still can use the help of better resolution.
The Phrygian Scale Formula
The Phrygian mode is just a natural minor scale with a b2 degree added.
Above when you play the E Phrygian that first E-F movement is what really gives the scale its vibe.
Because the b2 and b7 are so eager to resolve back to the tonic, this creates a scale that sounds off and sometimes disturbing. Plus the b2 interval to the 5 is a tritone, adding more dissonance.
It is no wonder it is used a lot in heavy metal riffs.
It is also common to see the scale known as Phrygian Dominant, and it has the formula:
It is also found in movies, like the intro here.
Depending on your genre choice you may be using the dominant version more than the regular Phrygian mode.
Phrygian Scale Fretboard Patterns
Here below you find the most common shapes for playing the Phrygian Scale. All these examples are provided in the key of C; as usual, you can shift these shapes up or down the neck to play the scale in another key. The table below the diagrams shows you the note for the Phrygian scale in all the keys.

Common Chords and Progressions
Normally to find the chords of a specific scale we use the same formulas as always. And in the case of the Phrygian and Locrian modes, the chords that form are not all that usable as progressions.
Please refer to the tables below to find the chords in this mode.
Therefore we often find these modes being used partially or in short bursts.
Using the scale to build chords, we can see a minor triad (1 b3 5) and a minor 7th chord can be built (1 b3 5 b7).
Otherwise it doesn't have many usable chords, but where this scale shines is when using the b2, these sus chords are the most important in the Phrygian mode.
A sus(b9) can be built using this scale, so it is called the Phrygian chord. That is the most likely chord you will be jamming over in this mode, or at least the best fit.
And these sus(b9) chords can be used to substitute over the V7 or any regular sus chords.
A regular jazz progression like II-V is a perfect place to try this placement of Phrygian.
While there are some chord progressions to be found, most of the time Phrygian is used as riffs over more stable sounds. In some cases the minor tonic triad or the iii is used as a drone while the 1 b2 and b6 are prominently played.
This is common in heavy metal, a Phrygian riff played over chords that sound better. This difference between the tonic and those tones produces the exotic flavor of the mode.
The Phrygian dominant has more uses with just the 3rd degree change. But it still doesn't produce the greatest chord progressions.
Just like regular Phrygian it is best played over regular progressions like II-V, or over any notes that sound and resolve better.
We will rarely come across pure Phrygian modal examples, you will mostly be playing the scale over other progressions to provide a contrast in sound.

Notable Examples Of Phrygian Mode
Phrygian is going to be one of the strangest and sometimes darkest modes you use, it is way more common than Locrian as that mode is far too unstable. And you usually see the dominant version, especially in the flamenco genre.
It is a very old mode so can be found in abundance in classical music, but we will focus on more modern examples.
These show the side of Phrygian that is exotic and unique, which is usually how it is used in jazz.
But we switch to heavy metal, and they use the darker side of the mode. "Wherever I May Roam", has a mix of exotic and dark vibes. Other great examples are "Reflections", "Jimmy", and other Tool songs; they love the Phrygian mode.
If you notice with metal Phrygian riffs, as they play that scale, there is another underlying droning or static note.
And of course we have rock and pop examples like "Spanish Caravan" If the song uses Spanish or flamenco terms, it likely has some Phrygian in it.
Often you will find examples like that final Beatles tune, mostly in another mode (Aeolian) but with passing Phrygian use. You cannot only identify this mode by its overall feeling, but as mentioned there is always a flattened second degree.
That b2 (or b9 as it is the same note) can and will be used when adding a "foreign" flavor to the song.
Phryigian Scale - Conclusions
The pure Phrygian mode is going to probably be your second least used (Locrian being last) in pure form unless you are in the Dominant one for flamenco.
Basically the pure Phrygian scale is used when you want an exotic and dark vibe in a guitar riff or solo.
However the whole song overall is rarely going to be all in this mode, as it needs some resolution to fit in better with modern music.
