Complete Guide to Piano Chord Types

Piano chords can be classified into various types based on their structure and sound.

Triads (Three-Note Chords)

Triads are the most basic type of chord, consisting of three notes: the root, third, and fifth. They form the foundation of harmony in Western music.

Major Chords

Major chords have a bright, happy sound. They are built with a root, major third, and perfect fifth (intervals 0-4-7). The C major chord (C-E-G) is one of the first chords most pianists learn.

C Major C# Major D Major D# Major E Major F Major F# Major G Major G# Major A Major A# Major B Major

Minor Chords

Minor chords have a dark, sad sound. They are built with a root, minor third, and perfect fifth (intervals 0-3-7). The A minor chord (A-C-E) is commonly used in emotional and melancholic music.

C Minor C# Minor D Minor D# Minor E Minor F Minor F# Minor G Minor G# Minor A Minor A# Minor B Minor

Augmented Chords

Augmented chords have a tense, mysterious sound. They are built with a root, major third, and augmented fifth (intervals 0-4-8). The symmetrical structure makes them sound unsettled and dreamy.

C Augmented C# Augmented D Augmented D# Augmented E Augmented F Augmented F# Augmented G Augmented G# Augmented A Augmented A# Augmented B Augmented

Diminished Chords

Diminished chords have a very tense, unstable sound. They are built with a root, minor third, and diminished fifth (intervals 0-3-6). They create strong tension that usually resolves to a more stable chord.

C Diminished C# Diminished D Diminished D# Diminished E Diminished F Diminished F# Diminished G Diminished G# Diminished A Diminished A# Diminished B Diminished

Seventh Chords (Four-Note Chords)

Seventh chords add a fourth note (the seventh) to a triad, creating richer, more complex harmonies. They are essential in jazz, blues, and many popular music styles.

Major 7th Chords

Major 7th chords add a major seventh to a major triad. They sound warm, jazzy, and sophisticated. Commonly used in jazz ballads and neo-soul music. The Cmaj7 chord (C-E-G-B) has a dreamy, relaxed quality.

C Major 7th C# Major 7th D Major 7th D# Major 7th E Major 7th F Major 7th F# Major 7th G Major 7th G# Major 7th A Major 7th A# Major 7th B Major 7th

Minor 7th Chords

Minor 7th chords add a minor seventh to a minor triad. They sound smooth and mellow. The Dm7 chord (D-F-A-C) is one of the most frequently used chords in jazz and R&B.

C Minor 7th C# Minor 7th D Minor 7th D# Minor 7th E Minor 7th F Minor 7th F# Minor 7th G Minor 7th G# Minor 7th A Minor 7th A# Minor 7th B Minor 7th

Dominant 7th Chords

Dominant 7th chords add a minor seventh to a major triad. They sound bluesy and create strong tension that pulls toward resolution. The G7 chord (G-B-D-F) is the V7 chord in the key of C major.

C Dominant 7th C# Dominant 7th D Dominant 7th D# Dominant 7th E Dominant 7th F Dominant 7th F# Dominant 7th G Dominant 7th G# Dominant 7th A Dominant 7th A# Dominant 7th B Dominant 7th

Diminished 7th Chords

Diminished 7th chords add a diminished seventh to a diminished triad. They are very tense and dramatic, often used as passing chords. Every interval is a minor third, making the chord symmetrical.

C Diminished 7th C# Diminished 7th D Diminished 7th D# Diminished 7th E Diminished 7th F Diminished 7th F# Diminished 7th G Diminished 7th G# Diminished 7th A Diminished 7th A# Diminished 7th B Diminished 7th

Half-Diminished 7th Chords

Half-diminished 7th chords (also called minor 7 flat 5) add a minor seventh to a diminished triad. They sound somber and are commonly found as the ii chord in minor key ii-V-I progressions.

C Half-Diminished 7th C# Half-Diminished 7th D Half-Diminished 7th D# Half-Diminished 7th E Half-Diminished 7th F Half-Diminished 7th F# Half-Diminished 7th G Half-Diminished 7th G# Half-Diminished 7th A Half-Diminished 7th A# Half-Diminished 7th B Half-Diminished 7th

Minor-Major 7th Chords

Minor-major 7th chords add a major seventh to a minor triad. They have a haunting, film-noir quality. This chord is less common but creates a distinctive, exotic sound when used sparingly.

C Minor-Major 7th C# Minor-Major 7th D Minor-Major 7th D# Minor-Major 7th E Minor-Major 7th F Minor-Major 7th F# Minor-Major 7th G Minor-Major 7th G# Minor-Major 7th A Minor-Major 7th A# Minor-Major 7th B Minor-Major 7th

How to Choose the Right Chord Type

With so many chord types available, it can feel overwhelming to know which ones to learn first. Here is a practical learning order that works well for most pianists:

  1. Major triads — Learn all 12 first. They are used everywhere and sound resolved.
  2. Minor triads — Another 12 chords that add emotional range. Most pop songs use a mix of major and minor triads.
  3. Dominant 7th chords — Essential for blues, rock, and jazz. They create the tension that drives progressions forward.
  4. Major 7th and minor 7th chords — The foundation of jazz harmony and very common in R&B and neo-soul.
  5. Diminished and augmented triads — Useful as passing chords and for adding color.
  6. Diminished 7th, half-diminished 7th, and minor-major 7th — Advanced chords that appear in jazz and classical music.

Following this order means you can start playing real songs quickly while building up to more complex harmony over time.

Frequently Asked Questions About Chord Types

How many different types of piano chords are there?

In theory, there are dozens of chord types when you include all possible extensions and alterations. However, for practical purposes, the 10 types covered on this page (4 triads + 6 seventh chords) are sufficient for playing most music you will encounter. Once you master these, extended chords (9th, 11th, 13th) and altered chords become much easier to understand.

What is the difference between a chord and a triad?

A triad is a specific type of chord that contains exactly three notes: the root, third, and fifth. A chord is a more general term that refers to any group of notes played together. So all triads are chords, but not all chords are triads — seventh chords, for example, have four notes, and extended chords can have five or more.

Why do some chords have a number in their name?

The number refers to the highest interval added to the basic triad. A "7" means a seventh note is added (like C7 or Cmaj7). A "9" means a ninth is added on top of the seventh (like C9). These numbers come from music theory's system of counting scale degrees.

What is the most important chord type to learn?

Major triads are the most essential — they are the foundation of harmony in Western music. After major and minor triads, dominant 7th chords are probably the next most important because of their central role in blues, rock, and jazz. Focus on these first, then expand your vocabulary based on the style of music you want to play.

Can I play any song with just major and minor chords?

Yes, actually! A surprising number of popular songs use only major and minor triads. Folk songs, early rock and roll, punk, country, and many pop hits rely on just these two chord types. Adding seventh chords gives you more color and sophistication, but it is not strictly necessary to play real music.
