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 Pentatonic
Minor Pentatonic
Blues-derived same-root sound where ♭3 acts as a ♯9 color against the chord's 3rd.
Pentatonic ∩ Diminished
Pentatonic ∩ Diminished
A compact intersection used to keep strong dominant/blues tones while reducing the full octatonic set.
Diminished °7
Diminished °7
Symmetric diminished arpeggio color.
Dominant Diminished H–W

Maximum common altered dominant tensions: ♭9, ♯9, altered 5ths and ♭7.
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
Start with Mixolydian
Establish the basic dominant sound before adding outside tension.
Practice
Compare one approach at a time
Keep multiple overlays visible and inspect exactly which notes change.
Practice
Resolve every tension
Use Target / Next chord to hear why a tension works rather than judging the scale in isolation.
FAQ

How should I practice scales over dominant 7 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 scales over dominant 7 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.
