Minor Chords

A minor triad is a major triad with one note moved: root, minor 3rd (3 semitones), perfect 5th (7 semitones) — identical to a major chord except the middle note sits a half-step lower. That single semitone is doing all the work of the "sadder" or more introspective character listeners associate with minor chords; the outer two notes (root and 5th) never move between the major and minor version of the same root.

This hub gathers four related qualities that share that minor 3rd as their defining interval: the plain minor triad, minor 6th (adds a major 6th, 9 semitones, on top — genuinely distinct from a minor 7th's darker pull), minor 7th (adds a minor 7th, 10 semitones — the workhorse minor-family extension in jazz, R&B, and neo-soul comping), and minor 9th (stacks a major 9th, 14 semitones, on top of the m7 shape for an even richer, more colorful minor sound common in jazz and modern pop production).

Every minor key is built outward from its i (tonic) minor triad the same way a major key is built from its I — but minor keys carry a genuine extra layer of complexity major keys don't: natural, harmonic, and melodic minor are three real, distinct scale forms, and which one a given passage draws from changes which notes (and therefore which chords) are actually available. The Modes Explained and Chord Function theory pages go deeper on how minor-key harmony diverges from the simpler picture major keys give.

A minor chord's relative-major relationship is one of the most genuinely useful facts in this hub: every minor key shares its exact 7 notes with a major key a minor 3rd above its root — A minor and C major share all seven notes, for instance, which is precisely why Am and C appear together constantly in real progressions (a vi-I or I-vi movement barely changes the underlying key color at all, since five of the six notes involved overlap). See Chord Substitution for more on how that relative relationship gets used deliberately, not just observed.

On guitar, Em, Am, and Dm all have comfortable open-position shapes (in fact Em and Am are frequently among the very first chords beginners learn, arguably ahead of most majors, because their open shapes need only one or two fingers); Bm and F#m, by contrast, need a barre, the same physical constraint that makes F major hard. On piano, minor triads and their extensions sit under the hand exactly as comfortably as their major counterparts — the physical reach is identical, only the middle-finger note changes. On ukulele, minor shapes are similarly compact thanks to the short scale and 4-string reentrant tuning.

Minor-key progressions carry a real structural wrinkle major keys don't: natural minor's v chord (built purely from the natural minor scale) is itself minor, which gives it noticeably less pull toward resolving back to the tonic than a major V chord has. Harmonic minor exists largely to fix this — it raises the natural minor scale's 7th degree by a semitone, which turns that v chord into a proper major V (with a leading tone a half-step below the tonic, the same strong pull major keys rely on). That's why so much minor-key harmony in classical and traditional music borrows this one altered note even while the melody stays largely in natural minor — a real, specific compromise rather than an inconsistency.

Minor 7th chords carry particular weight in neo-soul, R&B, and lo-fi/chill production specifically because their character sits between plain minor's starkness and minor 9th's fuller color — an m7 chord voiced with a rootless jazz-influenced voicing is one of the most recognizable harmonic fingerprints of that production style, frequently looped for entire song sections rather than moved through a full progression.

Minor keys carry real cultural and stylistic associations worth naming honestly rather than treating as universal: Western listeners very commonly (though not universally, and not as a strict rule) associate minor-key harmony with sadness, seriousness, or tension, and major-key harmony with brightness or resolution. That association is a learned cultural pattern rather than a physical law of the intervals themselves — some traditions and genres use minor-key harmony for driving, energetic material (much of metal and a lot of Eastern European and Middle Eastern folk music built on minor or related modes reads as intense rather than sad), which is a genuine, worthwhile complication to the oversimplified "minor equals sad" claim repeated uncritically on far too many chord sites.

Minor 6th chords are the quiet, less-discussed member of this family, and it's worth being direct about why: an m6 chord's added major 6th creates real ambiguity with a half-diminished 7th chord built a minor 3rd higher (in the same way major 6th relates to a minor 7th chord, covered in the Major Chords hub) — Am6 (A-C-E-F#) shares three of its four notes with F#m7b5, which is part of why m6 chords, while genuinely useful, see less use in mainstream songwriting than the more harmonically unambiguous plain minor, m7, and m9 chords covered alongside it in this hub.

The minor ii-V-i progression — built from a half-diminished 7th (ii), a dominant 7th (V, often with an altered 5th or 9th), and a minor chord (i, frequently voiced as m7 or m9) — is the minor-key counterpart to the major-key jazz ii-V-I covered in the Seventh Chords hub, and it's one of the most common harmonic movements in minor-key jazz standards. Recognizing it by ear across this hub's m7, m9, and the half-diminished chords documented in Diminished & Augmented Chords is a genuinely useful practical skill, not just an academic label.

Melodic minor is the third real minor scale form worth naming here even though StrumAndKey's Scales hub documents natural minor specifically (alongside major and the pentatonic/blues family) rather than all three minor variants as separate scale pages: melodic minor raises both the 6th and 7th degrees of natural minor when ascending (traditionally reverting to natural minor when descending, though modern jazz practice often uses the same raised form both directions), and it's the source of several extended and altered chord colors — including the m/maj7 chord (a minor triad with a major, not minor, 7th) heard in a lot of film scoring and sophisticated jazz harmony, distinct from every chord quality in StrumAndKey's main roster.

Minor chords voiced with the root removed create a genuine ambiguity worth flagging for anyone comping without a bass player present: an m7 chord with its root dropped is identical in pitch content to a major 6th chord built a minor 3rd below it (the same relative relationship covered in the Major Chords hub, just approached from the other direction) — which is exactly why a rootless minor 7th voicing sometimes reads as ambiguous in isolation and depends on the surrounding harmonic context, or an actual bass note played by someone else, to resolve which chord is really intended.

Minor chords are sometimes taught as simply "major chords with a flat 3rd," which is technically accurate but sells short how differently the two families actually function across the genres and hubs this site documents — a minor chord isn't a lesser or incomplete major chord, it's a fully independent tonal center with its own diatonic system, its own common progressions, and its own genuinely distinct emotional palette, covered on equal footing throughout this hub rather than as a footnote to the Major Chords page.

Songwriters working in minor keys often deliberately borrow a major IV or major V chord from the parallel major key (the major key sharing the same tonic note, e.g. C major borrowed into C minor) for a brief moment of unexpected brightness before returning to minor — a real, describable technique called modal mixture or borrowed chords that Chord Substitution touches on, and one of the more emotionally effective tools minor-key songwriting has precisely because it stands out against the surrounding minor harmony.

Video game and film scores dealing with loss, tension, or foreboding lean on this hub's minor-family chords constantly and deliberately, often specifically choosing m7 or m9 over a plain minor triad when the moment calls for something more resigned or wistful than starkly tragic — a real, describable difference in emotional color between the plain triad and its extended relatives that composers exploit on purpose. Recognizing that gradient — plain minor, m6, m7, m9, each a shade further from stark and closer to bittersweet — is a genuinely useful listening skill this hub's four qualities are organized specifically to build, and one worth practicing deliberately rather than assuming it develops automatically with time alone — sit with each of the four qualities back to back on the same root and notice, specifically, what changes.

This hub pulls together every minor, m6, m7, and m9 chord page across all 12 keys and all three instruments where that quality exists (m9 is guitar/piano only — ukulele's 10-quality roster stops at m7 and doesn't include m9).
