Guitar: Bb Rock 'n' Roll Over the Changes

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

Bb Rock 'n' Roll runs 6 notes to the octave, laid out here on EADGBE with every Bb 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.

A guitar chorus is a single line with the comp dropped, so a scale here is what the picking hand walks through between the two or three phrases it actually meant to play.

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.
