Episode 5 - Bass Guitar: The Hidden Engine

Drop your attention to the very bottom of a song — that low, round thing you feel in your chest more
than you hear. Almost nobody notices it, and it's holding the whole song together. The hidden engine.

• The bass's unique job: the hinge between rhythm and harmony — root notes define the chords, the kick-lock ("the pocket") drives the groove
• Why bass is felt: the physics of low frequencies working on your body
• Where it came from: piano left hand, upright/washtub bass, rockabilly slap → Leo Fender's Precision Bass (1951)
• The rhythm section: bass + drums as one four-limbed instrument
• The players:
  Willie Dixon (Chess bassist AND songwriter of the blues canon); jazz walking (Ray Brown); James Jamerson's melodic revolution
• Blues-rock heroes:
  Jack Bruce (Cream) & Paul McCartney make bass a voice; Bill Wyman, John Paul Jones;
  Berry Oakley (Allmans' "third guitar," "Whipping Post");
  Duck Dunn & Tommy Shannon (the pocket); Andy Fraser's use of space; Geezer Butler & Roger Glover go heavy
• Tone Recipe: P-bass vs J-bass, fingers vs pick, flat vs roundwound; power through clarity, not just boom
• Progression Spotlight: rooting, walking, and riffing the 12-bar; octaves, slides, connecting runs; tension & release as forward motion
