E minor pentatonic

Construction

Step pattern (W = whole step; m3 = minor-third gap, 3 half steps): m3-W-W-m3-W. Five notes, formula (intervals from the root): 1-b3-4-5-b7.

Minor pentatonic is the natural minor scale with the 2 and b6 removed -- the two degrees that clash most against a minor chord. What remains is pure minor essence: b3 sets the quality, 4 and 5 provide stability, and b7 adds bluesy weight without leading-tone pull.

Origin and Relationships

• Built from natural minor (1-2-b3-4-5-b6-b7) by omitting the 2 and b6. The 2 adds tension against the b3 (they sit a half step apart); b6 grinds against the 5 -- removing both leaves a scale that sits cleanly over any minor chord.
• Minor pentatonic is also a subset of Dorian (1-2-b3-4-5-6-b7) -- the same five notes remain when you strip away the 2 and 6. This means minor pentatonic works anywhere Dorian does, just with fewer color options.
• Same five notes, different root: minor pentatonic shares its entire note set with the major pentatonic a minor third above. Starting these same notes from the b3 gives you major pentatonic -- a relationship worth hearing, not just knowing.

Harmonic Context

In Roman numeral analysis (uppercase = major, lowercase = minor):

• i (minor): Every note is a chord tone or natural extension. No avoid notes.
• iv (minor): The b3 becomes the b7 of iv -- consonant and dark.
• v (minor): All notes fit the minor key without friction.
• V7 (dominant): A V7 chord contains a major 3rd, but this scale has b3 -- a minor 3rd. Playing both at once creates the gritty minor-over-major friction that defines the blues sound.

Characteristic Tones

The intervals that give this scale its distinctive sound:

• b3 (minor third): Defines the minor quality. Compare to Major Pentatonic: major pentatonic has 3 where minor pentatonic has b3 -- that single interval is the difference between bright and dark. Over dominant chords, the b3 rubs against the chord's natural 3, producing the tension at the heart of blues phrasing.
• b7 (minor seventh): Two half steps below the octave, the b7 gives the scale its bluesy, unresolved quality. No leading-tone pull toward the root, so phrases settle rather than push forward.

Melodic Applications

Minor pentatonic is the foundation of blues, rock, and much popular guitar melody. Target 1 and 5 for stability; lean on b3 and b7 for color and tension. The 4 works as a passing tone that resolves naturally to b3 or 5. Over a dominant chord, the b3-against-natural-3 clash is not a mistake -- it is expressive territory. Emphasize it to darken a phrase, or resolve it to 1 or 5 to release the tension.

Practice Seeds

Over dominant. Play minor pentatonic over a dominant seventh chord. The chord has a major 3rd; the scale has b3. Listen for that collision -- this friction is the blues sound in its simplest form.

Characteristic b7. Improvise using phrases that emphasize b7 resolving down to 5 or up to 1. Notice how b7 adds weight without the urgency of a leading tone -- this is what separates pentatonic phrasing from major-scale phrasing.

Find the major. Play minor pentatonic, then restart the same notes from the b3. Hear major pentatonic emerge -- same five notes, different tonal center. This builds awareness of the relative relationship and trains your ear to hear both scales inside one set of notes.

Add the blue note. Insert b5 between 4 and 5 to create the blues scale. One chromatic addition transforms the sound -- listen for how the b5 pulls toward 4 or 5 rather than resting in place.
