Adding chromatic notes to a pentatonic scale is one of the quickest ways to introduce a more sophisticated, outside flavour into your improvising — and it is something the great players have used for decades to make familiar patterns sound fresh and unexpected.
What you’ll get out of this lesson
A concise introduction to the idea of chromatic passing notes within pentatonic patterns, giving you an immediately usable tool to add colour and tension to your solos.
The Pentatonic as a Starting Point
The minor pentatonic is the foundation of so much guitar playing precisely because its five notes sit comfortably over a wide range of harmonic situations. That comfort, though, can also make it sound predictable. Introducing chromatic notes — notes that sit outside the scale — creates momentary tension that resolves beautifully back into the familiar tones.
Chromatic Passing Notes
A chromatic passing note is a note a semitone above or below a scale tone that you pass through on the way to your target note. Because you move through it quickly, the ear accepts it as part of the phrase rather than hearing it as a wrong note. The key is direction and resolution — land on a strong chord tone and the outside note gives the phrase a satisfying pull.
Applying the Idea Practically
Take any pentatonic lick you know well and experiment with inserting a chromatic note between two of its pitches. Notice how the character of the phrase shifts. Try placing the chromatic note on a weak beat so it resolves onto a chord tone on the strong beat — this is the most musical way to handle it.
Taking it further
Once you are comfortable with single chromatic additions, try two consecutive chromatic notes leading into a scale tone. This creates a brief but striking outside moment before the phrase snaps back into the key, a technique that opens up a huge range of melodic possibilities.
Your homework
Take one pentatonic lick you already know and add a single chromatic passing note somewhere in it. Practise the modified lick slowly until it feels natural, then try it over a backing track at a comfortable tempo. Aim to use it musically at least three times in an improvisation before moving on.
