- Beatles guitars play A minor pentatonic over both A7 and D7, creating clashes like C against C#.
- These clashes are common blues practice and contradict strict chord-scale expectations.

- Blues players bend pitches (blue notes) toward chord tones, creating tolerated microtonal clashes.
- Hein notes these bends should be dissonant by classical theory but sound normal in blues contexts.
