Going "outside" — and coming back

What “outside” means

In jazz and fusion, outside describes notes or scales that don’t belong to the current chord. They create tension. Used well, they sound sophisticated and modern. Used poorly, they sound like wrong notes.

The single rule:

Outside notes are only as good as their resolution.

Play any note. As long as you resolve it back to a chord tone within a beat or two, it works. The brain forgives anything if it returns home.

Simple outside techniques

1. Side-slipping

Play a phrase a half-step up or down from where you should be, then move back. So if the chord is G7 and you’d normally use G Mixolydian, play a fragment of A♭ Mixolydian instead, then return.

Example over G7: a phrase in G Mixolydian → same phrase shifted up a half-step (A♭) → back to G Mixolydian.

2. Chromatic enclosures

Surround a target chord tone with chromatic notes from both above and below. Already mentioned in Target & Approach, but worth stressing: chromatic notes are always on the way to a target. They never sit still.

3. Triadic superimposition

Play a triad whose notes are all “outside” but whose contour is clean. For example, over a C major chord, play a B major triad (B D♯ F♯) as a fast arpeggio. None of those notes is in C major — but the shape is clean, and if you resolve to a C major chord tone immediately after, it sounds intentional and modern.

4. Modal interchange in soloing

Over a major chord, play notes from the parallel minor (or vice versa). The flatted 3, ♭6, or ♭7 borrowed momentarily creates a moment of “blue” colour.

A common framework: pentatonic from a different root

To sound modern over a Cmaj7, try playing D minor pentatonic (D F G A C) — the 5 notes of Dm pent over a Cmaj7 outline 2-4-5-6-1 of C major = a beautiful, modern voicing of the Cmaj9 sound. Substitute one pentatonic for another and you get instant colour without learning new scales.

Common substitutions:

• Over maj7: play m pent from the 3rd (e.g. Em pent over Cmaj7) or m pent from the 6th (Am pent over Cmaj7).
• Over dom7: play m pent from the 5th (e.g. Dm pent over G7) — a slick bebop sound.
• Over m7: play m pent from the root, OR from the 5th (e.g. Em pent over Am7).

When to use outside playing

Sparingly. A solo that’s all outside playing is noise. A solo that goes outside for 4-8 bars in the middle of a chorus — and resolves cleanly — sounds like an electric moment.

The rule of thumb: 2/3 inside, 1/3 outside. And the outside material always resolves.

Try this

Improvise over a 1-chord vamp — just Am7 looped. Play 4 bars purely inside (A Dorian or A minor pentatonic). Then 4 bars of B♭ minor pentatonic — totally outside, one half-step up. Then 4 bars back inside Dorian, resolving to A.

The first time you try this it’ll feel like a train wreck. The third time it’ll click — your ear adjusts to hearing the half-step displacement as a deliberate musical move. After a few sessions you can do it on any chord.
