1 What Are Chromatic Approach Notes?
Chromatic approach notes are non-diatonic tones that resolve by half step into a target note, typically a chord tone or a strong scale degree. They are one of the defining characteristics of bebop and modern jazz guitar, adding tension, forward motion, and melodic sophistication to improvised lines. If your solos sound like you are simply running up and down scales, chromatic approaches are the tool that will transform them into something that actually sounds like jazz.
The concept is deceptively simple. Instead of arriving at a chord tone directly, you approach it from one half step above or below. This creates a brief moment of tension followed by satisfying resolution. The ear registers the chromatic note as a purposeful passing tone rather than a wrong note, provided it resolves cleanly into its target. Charlie Parker, Dizzy Gillespie, and every major bebop player built their vocabulary around this principle.
On guitar, chromatic approach notes are physically intuitive because a half step is just one fret. This makes them easy to execute once you understand where to place them. The challenge is not technical; it is conceptual. You need to know your chord tones cold so that you always have a clear target in mind. Without a target, a chromatic note sounds like a mistake. With a target, it sounds like genius. Understanding jazz chord voicings gives you the harmonic foundation needed to identify these targets across the fretboard.
Chromatic approaches are distinct from chromatic passing tones, which simply connect two diatonic notes by half steps. An approach note has a specific destination and rhythmic placement. It typically falls on a weak beat or the "and" of a beat, resolving to its chord tone target on the next strong beat. This rhythmic specificity is what makes approach notes sound intentional and musical rather than random.
2 Single Chromatic Approaches from Above and Below
The simplest chromatic approach is a single note one half step above or below your target. Approaching from below means playing the note one fret below your target and sliding or stepping up into it. Approaching from above means playing the note one fret above and stepping down. Both create tension and resolution, but they have different melodic characters. Below approaches tend to sound more resolved and final, while above approaches often sound more sophisticated and unexpected.
To practice single chromatic approaches, start by playing a major scale and approaching each chord tone from one half step below. Over a Cmaj7 chord, your targets are C, E, G, and B. Approach C from B, approach E from Eb (Ds), approach G from Gb (F#), and approach B from Bb. Notice that some of these approach notes are diatonic (B approaching C is already in the key) while others are truly chromatic (Eb approaching E introduces a non-scale tone). The chromatic ones are where the real color lives.
Single Chromatic Approaches - Targeting Chord Tones of Cmaj7
From Below (half step up into target):
Target: C E G B
Approach: B Eb F# Bb
(one fret below each target)
From Above (half step down into target):
Target: C E G B
Approach: Db F Ab C
(one fret above each target)
Example Line Over Cmaj7:
e|--------------------------------
B|------------------8--7---------- Ab→G (approach from above)
G|-----------5--4---------9--8---- Eb→E, then C→B
D|-----5--4---------------------- Bb→A... wait, A isn't a chord tone
A|--3----------------------------- C (root, target)
E|--------------------------------
Corrected: Always know your target!
Pro Tip
When approaching from below, the chromatic note should almost always fall on an upbeat (the "and" of the beat), with the target landing on the downbeat. This rhythmic placement is what makes the approach sound intentional. If the chromatic note lands on a strong beat and the target on a weak beat, the line loses its sense of direction.
Practice this concept slowly over a ii-V-I backing track, targeting just one chord tone at a time. Over Dm7, approach D from C# below. Over G7, approach B from Bb below. Over Cmaj7, approach E from Eb below. Keep your lines simple and focused. The goal at this stage is to train your ear to hear the approach-resolution pattern, not to play fast lines.
3 Double Chromatic Approaches
A double chromatic approach uses two consecutive chromatic notes to reach the target, creating an even stronger sense of forward motion. The most common pattern is two half steps from below: for a target of E, you would play C#-D#-E (or Db-Eb-E enharmonically). This creates a three-note chromatic run that propels the line forward with unmistakable bebop energy.
You can also approach from above with two chromatic notes: to target E, play F#-F-E. Or you can mix directions, approaching from below then above (or vice versa) before landing on the target. These mixed approaches create more angular, surprising melodic contours. Players like Pat Martino and Kurt Rosenwinkel use mixed-direction double approaches extensively to create lines that twist and turn unpredictably before landing on strong chord tones.
Double Chromatic Approaches to the Note G
Two from below: E - F# - G
Two from above: A - Ab - G
Below then above: F# - Ab - G
Above then below: Ab - F# - G
Applied Over Cmaj7 (targeting 5th = G):
e|----------------------------
B|----------------------------
G|---2--3--4------------------ E-F#-G (two from below)
D|----------------------------
A|----------------------------
E|----------------------------
e|----------------------------
B|----------------------------
G|---6--5--4------------------ A-Ab-G (two from above)
D|----------------------------
A|----------------------------
E|----------------------------
Double chromatic approaches work particularly well when targeting the 3rd and 7th of a chord, since these are the most harmonically defining tones. Over a G7 chord, approaching the 3rd (B) with a double chromatic from below (A-Bb-B) creates a line that practically screams "dominant seventh." This kind of targeted chromaticism is what separates jazz vocabulary from generic scale running. The enclosure technique takes this concept even further by surrounding the target from both sides simultaneously.
Pro Tip
Double chromatic approaches naturally fill in rhythmic gaps. If you need to connect two chord tones that are a whole step apart, a double chromatic approach from below fills in all the half steps. This is one reason bebop lines have that signature flowing, constant-eighth-note quality: chromatic approaches provide the connective tissue between chord tones.
4 Chromatic Approaches to Chord Tones
The real power of chromatic approach notes emerges when you systematically apply them to chord tones across an entire progression. In a ii-V-I in C (Dm7-G7-Cmaj7), each chord presents four chord tones as potential targets. Your job as an improviser is to select a target on each chord, approach it chromatically, then connect the resolution to the next approach smoothly.
A common strategy is to target the 3rd of each chord, since the 3rd defines the chord quality most clearly. Over Dm7, target F (the minor 3rd) by approaching from E (half step below). Over G7, target B (the major 3rd) by approaching from Bb (half step below). Over Cmaj7, target E (the major 3rd) by approaching from Eb (half step below). String these together and you have a line that outlines the harmony with clarity and chromatic color.

As you become comfortable targeting 3rds, expand to targeting 7ths, roots, and 5ths. Each target note produces a different melodic character over the same chord. Targeting the 7th of each chord creates a more sophisticated, inside-the-harmony sound. Targeting the root creates a more grounded, resolved effect. The ability to choose different targets on the fly gives you enormous creative freedom within a structured harmonic framework.
Understanding how modes apply to improvisation helps you contextualize these approach notes within the broader scale framework. Chromatic approaches work alongside modal knowledge, not as a replacement for it. You still need to know the diatonic scale for each chord; the chromatic notes are embellishments that add spice to a foundation of solid scale and arpeggio knowledge.
5 Combining Approach Notes with Bebop Lines
Bebop lines are characterized by continuous eighth notes with chord tones landing on downbeats. Chromatic approach notes are the mechanism that makes this work. When you play a scale in eighth notes, chord tones do not always fall on strong beats. Adding chromatic approach notes shifts the alignment so that important notes land on beats 1, 2, 3, and 4 while chromatic tones and passing tones fill the upbeats.
The bebop scale itself is a perfect example of this principle. The bebop dominant scale adds a chromatic passing tone (the natural 7th) to the Mixolydian mode, creating an eight-note scale that naturally aligns chord tones with downbeats when played in descending eighth notes. This single chromatic addition transforms a seven-note scale into a bebop machine. The same logic applies when you add approach notes to arpeggios and scale fragments.

When constructing longer bebop-style lines, think of chromatic approaches as connectors between arpeggio fragments. Play the 1-3-5 of a chord, use a chromatic approach to reach the 7th, descend the arpeggio, then use another approach to reach the 3rd of the next chord. This arpeggio-approach-arpeggio structure is the skeleton of classic bebop guitar as played by masters like Wes Montgomery, Grant Green, and jazz chord specialists who also excelled at single-note playing.
Pro Tip
Transcribe bebop solos by players like Charlie Parker (adapted for guitar) or Wes Montgomery and circle every chromatic approach note you find. You will discover that these masters used approach notes with remarkable consistency, almost always targeting chord tones on strong beats. Seeing the patterns in transcriptions makes the concept click faster than any abstract exercise.
6 Practice Strategies and Application
Begin your chromatic approach practice with a single chord vamp and a single target note. Loop a Dm7 backing track and spend five minutes approaching only the F (minor 3rd) from every direction: from below, from above, double from below, double from above, and mixed. Once that target feels automatic, switch to approaching the C (7th), then the A (5th), then the D (root). This focused, single-target approach builds deep familiarity faster than trying to do everything at once.
Next, practice over ii-V-I progressions at a slow tempo (60 BPM). Limit yourself to quarter notes at first, playing one approach note followed by one target note per beat. This forces you to be deliberate about every note choice. As the tempo increases, you can shift to eighth notes and begin linking approaches together into longer lines. The slow-to-fast progression ensures that your approach notes are always intentional, never accidental.
Apply chromatic approaches to tunes you already know. Take a jazz standard like "Autumn Leaves" and play through the changes using only arpeggios with chromatic approaches, no scale running allowed. This constraint forces you to rely on approach notes as your primary melodic tool and rapidly integrates them into your real-world vocabulary. Record yourself and listen back for moments where the approaches sound smooth and moments where they sound forced.
Finally, study how your favorite jazz guitarists use chromatic approaches in their solos. Transcribing even four bars of a Pat Martino or George Benson solo reveals how naturally and frequently great players use these techniques. The enclosure technique is a natural extension of chromatic approaches, and learning both concepts together accelerates your progress dramatically.
