Mode Construction | Phrygian Mode (3 of 7)
Similar to the Dorian mode, the notes of the Phrygian mode are essentially the same as the notes of the natural minor scale, except for the fact that the second scale degree of the Phrygian mode is flattened by one half step.
For this reason the Phrygian mode has a much more minor feel to it than the somewhat optimistic character of the Dorian mode.
For example, here are the notes of an A minor scale.
By flattening the second scale degree B one half step to the note B-flat we will have changed the notes from A minor to that of A Phrygian.
In that same respect, by looking at the notes of an E minor scale we can see that the second scale degree is the note F-sharp.
