Musicians use various kinds of chord names and symbols in different contexts to represent musical chords. In most genres of popular music, including jazz, pop, and rock, a chord name and its corresponding symbol typically indicate one or more of the following:
- the root note (e.g. CШаблон:Music),
- the chord quality (e.g. minor or lowercase m, or the symbols Шаблон:Music or + for diminished and augmented chords, respectively; chord quality is usually omitted for major chords),
- whether the chord is a triad, seventh chord, or an extended chord (e.g. Шаблон:Music7),
- any altered notes (e.g. sharp five, or Шаблон:Music5),
- any added tones (e.g. add2), and
- the bass note if it is not the root (e.g. a slash chord).
| Triad | Root | Quality | Example | Audio |
|---|---|---|---|---|
| Major triad | Uppercase | C | Файл:Major triad on C.mid | |
| Minor triad | Lowercase | c | Файл:Minor chord on C.mid | |
| Augmented triad | Uppercase | + | C+ | Файл:Augmented triad on C.mid |
| Diminished triad | Lowercase | o | co | Файл:Diminished triad on C.mid |
| Dominant seventh | Uppercase | 7 | C7 | Файл:Dominant seventh chord on C.mid |
For instance, the name C augmented seventh, and the corresponding symbol CШаблон:Sup, or CШаблон:Sup, are both composed of parts 1 (letter 'C'), 2 ('aug' or '+'), and 3 (digit '7'). These indicate a chord formed by the notes C–E–GШаблон:Sup–BШаблон:Sup. The three parts of the symbol (C, aug, and 7) refer to the root C, the augmented (fifth) interval from C to GШаблон:Music, and the (minor) seventh interval from C to BШаблон:Music.
Although they are used occasionally in classical music, typically in an educational setting for harmonic analysis, these names and symbols are "universally used in jazz and popular music",[1] in lead sheets, fake books, and chord charts, to specify the chords that make up the chord progression of a song or other piece of music. A typical sequence of a jazz or rock song in the key of C major might indicate a chord progression such as
- C – Am – Dm – GШаблон:Sup.
This chord progression instructs the performer to play, in sequence, a C major triad, an A minor chord, a D minor chord, and a G dominant seventh chord. In a jazz context, players have the freedom to add sevenths, ninths, and higher extensions to the chord. In some pop, rock and folk genres, triads are generally performed unless specified in the chord chart.
Purpose
These chord symbols are used by musicians for a number of purposes. Chord-playing instrumentalists in the rhythm section, such as pianists, use these symbols to guide their improvised performance of chord voicings and fills. A rock or pop guitarist or keyboardist might literally play the chords as indicated (e.g., the C major chord would be played by playing the notes C, E and G at the same time). In jazz, particularly for music from the 1940s bebop era or later, players typically have latitude to add in the sixth, seventh, and/or ninth of the chord. Jazz chord voicings often omit the root (leaving it to the bass player) and fifth. As such, a jazz guitarist might voice the C major chord with the notes E, A and D—which are the third, sixth, and ninth of the chord. The bassist (electric bass or double bass) uses the chord symbols to help improvise a bass line that outlines the chords, often by emphasizing the root and other key scale tones (third, fifth, and in a jazz context, the seventh).
The lead instruments, such as a saxophonist or lead guitarist, use the chord chart to guide their improvised solos. The instrumentalist improvising a solo may use scales that work well with certain chords or chord progressions, according to the chord-scale system. For example, in rock and blues soloing, the pentatonic scale built on the root note is widely used to solo over straightforward chord progressions that use I, IV, and V chords (in the key of C major, these would be the chords C, F, and GШаблон:Sup).
In a journal of the American Composers Forum the use of letters to indicate chords is defined as, "a reductive analytical system that views music via harmonic motion to and from a target chord or tonic".[2] In 2003 Benjamin, Horvit, and Nelson describe the use of letters to indicate chord root as, "popular music ([and/specifically] jazz) lead sheet symbols."[3] The use of letters, "is an analytical technique that may be employed along with, or instead of, more conventional methods of analysis such as Roman numeral analysis. The system employs letter names to indicate the roots of chords, accompanied by specific symbols to depict chord quality."[4]
Other notation systems for chords include:[5]
- Traditional staff notation.
- Roman numerals, commonly used in harmonic analysis.[6]
- figured bass, widely used in the Baroque era.
- numbered musical notation, a musical notation that use numbers characters instance of graphical symbols, widely used in China.
- Nashville Number System, a variant of modern chord symbols, that use Arabic numerals for scale degrees.
Chord quality
Chord qualities are related to the qualities of the component intervals that define the chord. The main chord qualities are:
- Major and minor
- Augmented, diminished, and half-diminished
- Dominant
Some of the symbols used for chord quality are similar to those used for interval quality:
- No symbol, or sometimes Шаблон:Serif or Шаблон:Serif for major
- Шаблон:Serif, or Шаблон:Serif for minor
- Шаблон:Serif for augmented
- Шаблон:Serif for diminished
In addition,
- Шаблон:Music is used for major seventh,Шаблон:Efn instead of the standard Шаблон:Serif, or Шаблон:Serif
- − is sometimes used for minor, instead of the standard Шаблон:Serif or Шаблон:Serif
- a lowercase root note is sometimes used for minor, e.g. Шаблон:Serif instead of Шаблон:Serif
- Шаблон:Music is used for augmented (Шаблон:Serif is not used)
- Шаблон:Music is for diminished (Шаблон:Serif is not used)
- Шаблон:Music is used for half-diminished
- Шаблон:Serif may occasionally be used for dominant
Chord qualities are sometimes omitted. When specified, they appear immediately after the root note or, if the root is omitted, at the beginning of the chord name or symbol. For instance, in the symbol Cm7 (C minor seventh chord) C is the root and m is the chord quality. When the terms minor, major, augmented, diminished, or the corresponding symbols do not appear immediately after the root note, or at the beginning of the name or symbol, they should be considered interval qualities, rather than chord qualities. For instance, in CmM7 (minor major seventh chord), m is the chord quality and M refers to the Шаблон:Music interval.
Major, minor, augmented, and diminished chords
Three-note chords are called triads. There are four basic triads (major, minor, augmented, diminished). They are all tertian—which means defined by the root, a third, and a fifth. Since most other chords are made by adding one or more notes to these triads, the name and symbol of a chord is often built by just adding an interval number to the name and symbol of a triad. For instance, a C augmented seventh chord is a C augmented triad with an extra note defined by a minor seventh interval:
| CШаблон:MusicШаблон:Music | = | CШаблон:Music | + | Шаблон:MusicШаблон:Music |
| augmented seventh chord |
augmented triad |
minor seventh |
In this case, the quality of the additional interval is omitted. Less often, the full name or symbol of the additional interval (minor, in the example) is provided. For instance, a C augmented major seventh chord is a C augmented triad with an extra note defined by a major seventh interval:
| CШаблон:MusicШаблон:MusicШаблон:Music | = | CШаблон:Music | + | Шаблон:Music |
| augmented major seventh chord |
augmented triad |
major seventh |
In both cases, the quality of the chord is the same as the quality of the basic triad it contains. This is not true for all chord qualities: the chord qualities half-diminished and dominant refer not only to the quality of the basic triad but also the quality of the additional intervals.
Altered fifths
A more complex approach is sometimes used to name and denote augmented and diminished chords. An augmented triad can be viewed as a major triad in which the perfect fifth interval (spanning 7 semitones) has been substituted with an augmented fifth (8 semitones). A diminished triad can be viewed as a minor triad in which the perfect fifth has been substituted with a diminished fifth (6 semitones). In this case, the augmented triad can be named major triad sharp five, or major triad augmented fifth (MШаблон:Music5, M+5, majaug5). Similarly, the diminished triad can be named minor triad flat five, or minor triad diminished fifth (mШаблон:Music5, mШаблон:Music5, mindim5).
Again, the terminology and notation used for triads affects the terminology and notation used for larger chords, formed by four or more notes. For instance, the above-mentioned C augmented major seventh chord, is sometimes called C major seventh sharp five, or C major seventh augmented fifth. The corresponding symbol is CM7+5, CM7Шаблон:Music5, or Cmaj7aug5:
| CM7+5 | = | C | + | M3 | + | A5 | + | M7 |
| augmented chord |
chord root |
major interval |
augmented interval |
major interval |
- (In chord symbols, the symbol A, used for augmented intervals, is typically replaced by + or Шаблон:Music)
In this case, the chord is viewed as a C major seventh chord (CM7) in which the third note is an augmented fifth from root (GШаблон:Music), rather than a perfect fifth from root (G). All chord names and symbols including altered fifths, i.e., augmented (Шаблон:Music5, +5, aug5) or diminished (Шаблон:Music5, Шаблон:Music5, dim5) fifths can be interpreted in a similar way.
Common types of chords
Triads
Шаблон:Image frameAs shown in the table below, there are four triads, each made up of the root, the third (either major [M3] or minor [m3]) above the root, and the fifth (perfect [P5], augmented [A5], or diminished [d5]) above the root. The table below shows the names, symbols, and definition for the four triads, using C as the root.

Seventh chords
Шаблон:Image frameA seventh chord is a triad with a seventh. The seventh is either a major seventh [M7] above the root, a minor seventh [m7] above the root (flatted 7th), or a diminished seventh [d7] above the root (double flatted 7th). Note that the diminished seventh note is enharmonically equivalent to the major sixth above the root of the chord.
The table below shows the names, symbols, and definitions for the various kinds of seventh chords, using C as the root.
Extended chords
Extended chords add further notes to seventh chords. Of the seven notes in the major scale, a seventh chord uses only four (the root, third, fifth, and seventh). The other three notes (the second, fourth, and sixth) can be added in any combination; however, just as with the triads and seventh chords, notes are most commonly stacked – a seventh implies that there is a fifth and a third and a root. In practice, especially in jazz, certain notes can be omitted without changing the quality of the chord. In a jazz ensemble with a bass player, the chord-playing instrumentalists (guitar, organ, piano, etc.) can omit the root, as the bass player typically plays it.
Ninth, eleventh, and thirteenth chords are known as extended tertian chords. These notes are enharmonically equivalent to the second, fourth, and sixth, respectively, except they are more than an octave above the root. However, this does not mean that they must be played in the higher octave. Although changing the octave of certain notes in a chord (within reason) does change the way the chord sounds, it does not change the essential characteristics or tendency of it. Accordingly, using the ninth, eleventh, or thirteenth in chord notation implies that the chord is an extended tertian chord rather than an added chord.
The convention is that using an odd number (7, 9, 11, or 13) implies that all the other lower odd numbers are also included. Thus C13 implies that 3, 5, 7, 9, and 11 are also there. Using an even number such as 6, implies that only that one extra note has been added to the base triad e.g. 1, 3, 5, 6. Remember that this is theory, so in practice they do not have to be played in that ascending order e.g. 5, 1, 6, 3. Also, to resolve the clash between the third and eleventh, one of them may be deleted or separated by an octave. Another way to resolve might be to convert the chord to minor by lowering the third, which generates a clash between the Шаблон:Music3 and the 9.
Ninth chords
Шаблон:Image frameNinth chords are built by adding a ninth to a seventh chord, either a major ninth [M9] or a minor ninth [m9]. A ninth chord includes the seventh; without the seventh, the chord is not an extended chord but an added tone chord—in this case, an add 9. Ninths can be added to any chord but are most commonly seen with major, minor, and dominant seventh chords. The most commonly omitted note for a voicing is the perfect fifth.
The table below shows the names, symbols, and definitions for the various kinds of ninth chords, using C as the root.

Eleventh chords
Шаблон:Image frameEleventh chords are theoretically ninth chords with the 11th (or fourth) added. However, it is common to leave certain notes out. The major third is often omitted because of a strong dissonance with the 11th, making the third an avoid note.Шаблон:Citation needed Omission of the third reduces an 11th chord to the corresponding 9sus4 chord (suspended 9th chord[7]). Similarly, omission of the third as well as fifth in C11 results in a major chord with alternate base BШаблон:Music/C, which is characteristic in soul and gospel music. For instance:
- C11 without 3rd = C–(E)–G–BШаблон:Music–D–F ➡ C–F–G–BШаблон:Music–D = C9sus4
- C11 without 3rd and 5th = C–(E)–(G)–BШаблон:Music–D–F ➡ C–F–BШаблон:Music–D = BШаблон:Music/C
If the ninth is omitted, the chord is no longer an extended chord but an added tone chord. Without the third, this added tone chord becomes a 7sus4 (suspended 7th chord). For instance:
- C11 without 9th = C7add11 = C–E–G–BШаблон:Music–(D)–F
- C7add11 without 3rd = C–(E)–G–BШаблон:Music–(D)–F ➡ C–F–G–BШаблон:Music = C7sus4
The table below shows the names, symbols, and definitions for the various kinds of eleventh chords, using C as the root.

Alterations from the natural diatonic chords can be specified as C9Шаблон:Music11 ... etc. Omission of the fifth in a raised 11th chord reduces its sound to a Шаблон:Music5 chord.[8]
- C9Шаблон:Music11 = C–E–(G)–BШаблон:Music–D–FШаблон:Music ➡ C–E–GШаблон:Music–BШаблон:Music–D = C9Шаблон:Music5.
Thirteenth chords
Шаблон:Image frameThirteenth chords are theoretically eleventh chords with the 13th (or sixth) added. In other words, theoretically they are formed by all the seven notes of a diatonic scale at once. Again, it is common to leave certain notes out. After the fifth, the most commonly omitted note is the 11th (fourth). The ninth (second) may also be omitted. A very common voicing on guitar for a 13th chord is just the root, third, seventh and 13th (or sixth). For example: C–E–(G)–BШаблон:Music–(D)–(F)–A, or C–E–(G)–A–BШаблон:Music–(D)–(F). On the piano, this is usually voiced C–BШаблон:Music–E–A.
The table below shows the names, symbols, and definitions for some thirteenth chords, using C as the root.

Alterations from the natural diatonic chords can be specified as C11Шаблон:Music13 ... etc.
Added tone chords
There are two ways to show that a chord is an added tone chord, and it is very common to see both methods on the same score. One way is to simply use the word 'add', for example, Cadd 9. The second way is to use 2 instead of 9, implying that it is not a seventh chord, for instance, C2. Note that this provides other ways of showing a ninth chord, for instance, C7add 9, C7add 2, or C7/9. Generally however, this is shown as simply C9, which implies a seventh in the chord. Added tone chord notation is useful with seventh chords to indicate partial extended chords, for example, C7add 13, which indicates that the 13th is added to the 7th, but without the 9th and 11th.
The use of 2, 4, and 6 rather than 9, 11, and 13 indicates that the chord does not include a seventh unless explicitly specified. However, this does not mean that these notes must be played within an octave of the root, nor the extended notes in seventh chords should be played outside of the octave, although it is commonly the case. 6 is particularly common in a minor sixth chord (also known as minor/major sixth chord, as the 6 refers to a major sixth interval).
It is possible to have added tone chords with more than one added note. The most commonly encountered of these are 6/9 chords, which are basic triads with the sixth and second notes of the scale added. These can be confusing because of the use of 9, yet the chord does not include the seventh. A good rule of thumb is that if any added note is less than 7, then no seventh is implied, even if there are some notes shown as greater than 7.
Suspended chords
Шаблон:Image frameSuspended chords are notated with the symbols "sus4" or "sus2". When "sus" is alone, the suspended fourth chord is implied. This "sus" indication can be combined with any other notation. For example, the notation C9sus4 refers to a ninth chord with the third replaced by the fourth: C–F–G–BШаблон:Music–D. However, the major third can also be added as a tension above the fourth to "colorize" the chord: C–F–G–BШаблон:Music–D–E. A sus4 chord with the added major third (sometimes called a major 10th) can also be voiced quartally as C–F–BШаблон:Music–E.
Power chords
Though power chords are not true chords per se, as the term "chord" is generally defined as three or more different pitch classes sounded simultaneously, and a power chord contains only two (the root, the fifth, and often a doubling of the root at the octave), power chords are still expressed using a version of chord notation. Most commonly, power chords (e.g., C–G–C) are expressed using a "5" (e.g., C5). Power chords are also referred to as fifth chords, indeterminate chords, or neutral chordsШаблон:Citation needed (not to be confused with the quarter tone neutral chord, a stacking of two neutral thirds, e.g. C–EШаблон:Music–G) since they are inherently neither major nor minor; generally, a power chord refers to a specific doubled-root, three-note voicing of a fifth chord.
To represent an extended neutral chord, e.g., a seventh (C–G–BШаблон:Music), the chord is expressed as its corresponding extended chord notation with the addition of the words "no3rd," "no3" or the like. The aforementioned chord, for instance, could be indicated with C7no3.
Slash chords
Шаблон:Image frameAn inverted chord is a chord with a bass note that is a chord tone but not the root of the chord. Inverted chords are noted as slash chords with the note after the slash being the bass note. For instance, the notation C/E bass indicates a C major triad in first inversion i.e. a C major triad with an E in the bass. Likewise the notation C/G bass indicates that a C major chord with a G in the bass (second inversion).
See figured bass for alternate method of notating specific notes in the bass.
Upper structures are notated in a similar manner to inversions, except that the bass note is not necessarily a chord tone. For example:
- C/AШаблон:Music bass (AШаблон:Music–C–E–G), which is equivalent to AШаблон:MusicM7Шаблон:Music5,
- CШаблон:Music/E bass (E–GШаблон:Music–CШаблон:Music–EШаблон:Music), and
- Am/D bass (D–A–C–E).
Chord notation in jazz usually gives a certain amount of freedom to the player for how the chord is voiced, also adding tensions (e.g., 9th, 11th, 13th, etc.) at the player's discretion. Therefore, upper structures are most useful when the composer wants musicians to play a specific tension array.
These are also commonly referred as "slash chords". A slash chord is simply a chord placed on top of a different bass note. For example:
- D/FШаблон:Music is a D chord with FШаблон:Music in the bass, and
- A/CШаблон:Music is an A chord with CШаблон:Music in the bass.
Slash chords generally do not indicate a simple inversion (which is usually left to the chord player's discretion anyway), especially considering that the specified bass note may not be part of the chord to play on top. The bass note may be played instead of or in addition to the chord's usual root note, though the root note, when played, is likely to be played only in a higher octave to avoid "colliding" with the new bass note.
Polychords
Polychords, as the name suggests, are combinations of two or more chords. The most commonly found form of a polychord is a bichord (two chords played simultaneously) and is written as follows: Шаблон:Sfrac, for example: Шаблон:Sfrac (C–E–G—B–DШаблон:Music–FШаблон:Music).
Other symbols
The right slash (/) or diagonal line written above the staff where chord symbols occur is used to indicate a beat during which the most recent chord symbol is understood to continue. It is used to help make uneven harmonic rhythms more readable. For example, if written above a measure of standard time, "C / F G" would mean that the C chord symbol lasts two beats while F and G last one beat each. The slash is separated from the surrounding chord symbols so as not to be confused with the chord-over-a-bass-note notation that also uses a slash. Some fake books extend this slash rhythm notation further by indicating chords that are held as a whole note with a diamond, and indicating unison rhythm section rhythmic figures with the appropriate note heads and stems.
A simile mark in the middle of an otherwise empty measure tells the musician to repeat the chord or chords of the preceding measure. When seen with two slashes instead of one it indicates that the previous measure's chords should be repeated for two further measures, called a double simile, and is placed on the measure line between the two empty bars. It simplifies the job of both the music reader (who can quickly scan ahead to the next chord change) and the copyist (who doesn't need to repeat every chord symbol).
The chord notation Шаблон:Serif indicates the musician should play no chord. The duration of this symbol follows the same rules as a regular chord symbol. This is used by composers and songwriters to indicate that the chord-playing musicians (guitar, keyboard, etc.) and the bass player should stop accompanying for the length covered by the "No Chord" symbol. Often the "No Chord" symbol is used to enable a solo singer or solo instrumentalist to play a pickup to a new section or an interlude without accompaniment.
An even more stringent indication for the band to tacet (stop playing) is the marking solo break. In jazz and popular music, this indicates that the entire band, including the drummer and percussionist, should stop playing to allow a solo instrumentalist to play a short cadenza, often one or two bars long. This rhythm section tacet creates a change of texture and gives the soloist great rhythmic freedom to speed up, slow down, or play with a varied tempo.
