Harmony first
Where this scale fits.
ChordRevelation treats scale choice as a relationship between chord formula, function and target — not as a root-name lookup.
Minor harmony

Dominant / blues
Dominant / blues
Minor Pentatonic can also be used over dominant chords as a blues-derived color, not only over minor chords.
Fretboard practice
Turn the formula into usable guitar vocabulary.
Keep chord tones visible, compare overlays and practice toward the next chord instead of running patterns without a harmonic destination.
Practice
Learn intervals before boxes
Know where 1, ♭3, 4, 5 and ♭7 are inside every minor-pentatonic position.
Practice
Connect positions
Move horizontally and diagonally instead of treating five boxes as separate scales.
Practice
Target chord tones
Resolve phrases to the actual chord voicing rather than ending every lick on the root.

How should I practice pentatonic scale on guitar?
Connect the interval formula to chord tones and real harmonic context, then compare positions on the fretboard instead of memorizing a single box.
Can I use pentatonic scale over every chord with the same root?
No. Scale choice depends on chord quality, harmonic function, key context and the next target chord, not only the root name.
