Guitar Start Guide
If your open chords are starting to sound a little plain, seventh chords are the next step up — and the seventh chords guitar players lean on give you that bluesy, jazzy, soulful colour with only one extra note. They sound advanced, but they’re just a normal triad with a fourth note stacked on top. Learn a couple of easy shapes and you’ll add real richness to songs you already know.
This guide explains what the “seventh” actually adds, the three types you’ll meet most, and a few beginner-friendly shapes to try.
A quick recap: chords are stacked notes
A basic chord (a triad) is three notes: root, third, and fifth. A seventh chord just keeps stacking in the same pattern and adds one more note — the seventh degree of the scale. So where a C major chord is C-E-G, a C seventh chord adds a fourth note on top. If triads are new to you, read how chords are built first; it makes everything here click. For the wider map, our guitar music theory for beginners guide helps too.
What the seventh adds
That extra note adds tension and character. A plain major chord sounds resolved and “finished”; adding a seventh gives it a pull, a sense that it wants to move somewhere. That’s why seventh chords are everywhere in blues, soul, funk, and jazz — they keep the music feeling alive and in motion. Used well, a single seventh chord can transform a boring progression into something that grooves.
The three seventh chords to know
There are a few kinds, but these three cover the vast majority of what beginners need:
| Type | Written as | Formula | Sound |
|---|---|---|---|
| Dominant 7th | C7 | Major triad + flat 7th | Bluesy, restless |
| Major 7th | Cmaj7 | Major triad + major 7th | Dreamy, warm, jazzy |
| Minor 7th | Cm7 | Minor triad + flat 7th | Smooth, mellow, soulful |
The naming trips people up, so remember this: plain “7” means the dominant seventh (the bluesy one), “maj7” is the dreamy one, and “m7” is the smooth minor one. Whether the underlying triad is major or minor is the same distinction you learned in major vs minor chords.
Easy beginner shapes to try
- E7 and A7: tiny tweaks to the open E and A chords — some of the easiest seventh chords on the guitar.
- G7: a friendly open shape that adds instant blues flavour.
- Dm7 and Am7: mellow, easy fingerings great for soul and pop.
- Cmaj7: lift one finger off an open C chord and you’re most of the way there — pure dreamy warmth.
Try swapping a plain chord for its seventh version in a song you already play and listen to how the mood changes. Knowing your notes on the fretboard helps you see exactly which note the seventh adds.
Where you’ll hear seventh chords
The 12-bar blues is built almost entirely on dominant seventh chords. Soul and R&B lean on minor sevenths for their smooth feel. Jazz and bossa nova live on major and minor sevenths. Even plenty of pop songs slip a seventh in to add colour at just the right moment. Once your ear knows the sound, you’ll start hearing them everywhere — and understanding how they drive a chord progression forward.
How to practise them
- Learn E7, A7, and G7 first — they’re the gateway to blues.
- Practise changing between them cleanly, just like your first open chords.
- Play a simple 12-bar blues in E using E7, A7, and B7.
- Then add Cmaj7 and Am7 to hear the softer, jazzier side.

Frequently Asked Questions
Are seventh chords hard for beginners?
Many are actually easier than the chords you already know — E7 and A7 are small changes to open shapes. Start with those and you’ll be playing seventh chords in a single session.
What’s the difference between C7 and Cmaj7?
They use different seventh notes. C7 (dominant) has a flat seventh and sounds bluesy and restless; Cmaj7 has a major seventh and sounds dreamy and warm. The name tells you which one you’re playing.
When should I learn seventh chords?
Once you’re comfortable changing between the basic open chords. Seventh chords are a natural next step that add a lot of expression without much extra difficulty.
Why do seventh chords sound “jazzy”?
The added seventh note creates gentle tension and richness that plain triads lack. Jazz and blues use that tension deliberately to keep the music feeling like it’s moving forward.
