Approach Notes · Jazz Wiki

An approach note is a non-chord tone that resolves by step into a chord tone landing on a strong beat. That tiny motion — tension on the weak part of the beat, release on the strong part — is Tension and Release at its smallest possible scale, and it’s the single most important trick that makes a scale run sound like a line. Learn to place approach notes correctly and a chord-tone arpeggio stops sounding like an exercise and starts sounding like Bird.

What makes a note an “approach”

An approach note only has one job: point at a target and land right before it. It sits on a weak beat or an upbeat, and the chord tone it’s aiming at lands on the next strong beat — usually beat 1, 3, or the downbeat of a new chord in the progression. There are two flavors, distinguished by the distance to the target:

Chromatic approach: a half step above or below the target, independent of key
Diatonic approach: a scale step (often a whole step) adjacent to the target, drawn from the prevailing key or chord scale

Direction changes the flavor of the resolution: approaching from below feels like it’s climbing into the target with energy, while approaching from above feels like it’s settling down and resolving. Chromatic approaches from below tend to sound subtle and slippery; chromatic approaches from above are the ones your ear really notices, because they cross outside the key.

Targeting the chord tones of Cmaj7

Say the target is the 5th of Cmaj7, which is G. Here’s the same target approached four different ways:

Chromatic from below: F♯ (weak beat) → G (strong beat)
Chromatic from above: A♭ (weak beat) → G (strong beat)
Diatonic from below: F (weak beat) → G (strong beat)
Diatonic from above: A (weak beat) → G (strong beat)

Here are all four approaches into that G, one per bar:

The same logic applies to any target note in the chord — root, 3rd, 5th, or 7th:

E (3rd) chromatic from below: D♯ → E
E (3rd) from above: F → E (here the diatonic neighbor happens to be the chromatic upper neighbor — the two categories can coincide)
B (7th) chromatic from below: B♭ → B

A rarer, more advanced move is the double-chromatic approach: two chromatic notes in a row from the same direction, stacking two units of tension before the release — for instance D then D♯, both driving up into E. This is a cousin of the enclosure, where the target instead gets bracketed from both sides at once, but a true single approach only ever comes from one direction at a time.

Approach notes across a ii–V–I

Over Dm7 – G7 – Cmaj7 in C major, approach notes are how bebop players connect one chord’s target to the next chord’s target without the line ever feeling static:

Dm7 (D–F–A–C): approach F from E (chromatic below)
G7 (G–B–D–F): approach B from A♯ (chromatic below), or approach D from C♯ (chromatic below)
Cmaj7: approach E from D♯ (chromatic below) or from F (diatonic above)

Notice that each approach note resolves exactly on the arrival of the next chord — the weak-beat/strong-beat rule holds even as the harmony itself is changing underneath the line. This is the backbone of ii-V-I Vocabulary and a core piece of Bebop Melodic Language: string together enough of these half-step resolutions and you get the instantly recognizable sound of Bebop.

Why this isn’t the same as a passing tone or an enclosure

It’s easy to lump approach notes in with other kinds of non-chord tones, but the distinction matters for how you practice them. A passing tone fills space between two chord tones without the strong-beat-landing discipline that defines an approach note — it’s decorative, not goal-directed. An enclosure, by contrast, uses two approach notes at once, bracketing the target from above and below before resolving; it’s a distinct, more elaborate device covered in its own note. Keep single approaches — one note, one direction, one resolution — as the foundation before you start combining them, since they’re also what most directly demonstrates Chromaticism in Jazz and Voice Leading principles borrowed from classical tendency-tone resolution.

♫ Listen

Charlie Parker — “Billie’s Bounce” (Savoy Records, 1945): Parker’s three-chorus solo is loaded with half-step approach notes resolving into chord tones over this F blues — listen for the F–D♯–E shape recurring throughout.
Charlie Parker — “Confirmation” (1953): the head melody and solo target the 3rds and the characteristic ♭5 of the half-diminished chords with tightly placed chromatic approaches, a great study in Playing the Changes.
Clifford Brown — “Joy Spring” (1954): Brown’s crisp trumpet articulation makes the diatonic and chromatic approach notes easy to isolate by ear, especially through the bridge.
