Five chords
that fix your comping

Your chords aren't lacking notes — they're lacking the right notes. Here's the fusion fix: drop the root, keep the colour, voice it on top.

The whole idea

Why your chords sound flat

If your comping feels thin or "stuck," it's almost always one of two habits: full barre chords with the root droning on the bottom, or plain triads and 7ths with no colour tones. Fusion harmony is the cure for both, and it rests on three simple ideas. Get these and your chords change overnight.

IDEA 01

Drop the root

The bass already has the root. You don't need it too. Move your voicings onto the top four strings — instantly lighter and more sophisticated.

IDEA 02

The 3rd & 7th rule

Those two "guide tones" decide major / minor / dominant. They are the chord. Keep them; everything else is decoration.

IDEA 03

Colour with 9 · 11 · 13

The extensions are what make a chord sound like fusion instead of folk. A 9th, a #11, a 13th — that's the whole flavour.

Progressions to learn

The takeaway

Five shapes, endless tunes

Everything above is built from a tiny set of moveable rootless shapes. Learn these five and you can comp through most fusion tunes — you're just sliding them to new frets.

maj9The "home" chord. Bright, resolved, open. Built from 3 · 5 · 7 · 9. Used for any I chord or static major vamp.
m9The workhorse. Warm and modern. Built from b3 · 5 · b7 · 9. Used for any minor chord — ii chords, minor vamps, Dorian grooves.
13The dominant. Tense, wants to move. Built from 3 · b7 · 9 · 13. Used for any V chord — far richer than a plain 7.
9#11The spice. The single most "fusion" sound. A dominant with a raised 11th — used for backdoor chords and any time you want bite.
6/9The smooth ending. A major chord with no 7th at all — 3 · 5 · 6 · 9. Soft, final, no tension. The classic last chord of a tune.
How to practise

Get them under the hand

1One shape at a time. Take just the m9 shape. Find it, hold it, look at it. Say the notes out loud. Then the maj9. No rush.
2Watch the top note. As you change chords, notice the highest note. Smooth comping means it moves by small steps — that's voice leading.
3Play with the MIDI. Loop fusion_chord_progressions.mid. It plays the bass for you — so you HEAR the root you've dropped doing its job.
4Strum once, let it ring. Don't rush the changes. One soft strike per bar, listen to the whole chord bloom, then move.
5Then move them. A shape is moveable. Slide the m9 up two frets and it's a new m9. That's how five shapes become every song.

Your backing file

All five progressions, looped

fusion_chord_progressions.mid

A Rhodes-and-bass rendering of every progression on this page, each played through twice with a bar of silence between sets. Crucially, the bass plays the roots you've been dropping — so you can comp the rootless top-string shapes against it and hear the full harmony lock together.

Load it in any DAW or MIDI player and loop it. If your player ignores the patch changes, set track 1 to an electric piano and track 2 to a bass. Mute the chord track and comp along yourself; mute the bass track and practise the progressions solo.
