This example is presented in order to more clearly demonstrate the possibilities offered by utilizing the aforementioned "B.B. box" scale position. This entire 12-bar solo is played in the 11th-fret "B.B. box," moving from lines based on Bb major pentatonic (Bb C D F G) in bars 1-3, moving to Bb minor pentatonic (Bb Db Eb F Ab) when playing over the IV (four) chord in bars 5 and 6 (with a pickup into bar 5 at the end of bar 4). This is followed by a return to Bb major pentatonic for the remainder of the solo.
