25.34Mix blues vocabulary with guide tones

A strong strategy:

Most of the time:

C blues/minor pentatonic.

At chord changes:

target the 3rd or 7th of the new chord.

Example:

C7 → F7:

approach A.

F7 → C7:

approach E.

G7 → C:

approach B → C or F → E.

Now the solo follows harmony while retaining blues character.
