Electric Bass: F Rock 'n' Roll Over the Changes

Where F Rock 'n' Roll lies at this seat, and what a chorus takes out of it.

F Rock 'n' Roll runs 6 notes to the octave, laid out here on EADG with every F flagged. Mid-chorus the pattern is not what you need; where the root is when the chord changes underneath you is.

Major pentatonic with a b3 rubbed against the natural 3 — bright and bouncy with a bluesy smirk. Playful, swinging, and built for boogie riffs.

Heard in: Fifties rock, rockabilly, boogie-woogie, Chuck Berry-style riffs, and jump blues.

The electric bass can hold a note long enough for it to be heard as a choice rather than a step, so a scale here is read for its strong tones first and its passing tones second.

Play it slowly against the audio until it stops being a shape, then put it over two bars of a form and let the chord tones decide which of the notes you actually keep.
