Chord names and symbols (jazz and pop music)
C7
, or major seventh chord on C Play.
Various kinds of chord names and symbols are used in different
contexts, to represent musical chords. In jazz and popular music, a
chord name and the corresponding symbol are typically composed of
one or more of the following parts:
1. The root note (e.g. C).
2. The chord quality (e.g. major, maj, or M).
3. The number of an interval (e.g. seventh, or 7), or less often its full
name or symbol (e.g. major seventh, maj7, or M7).
4. The altered fifth (e.g. sharp five, or 5).
5. An additional interval number (e.g. add 13 or add13), in added tone chords.
For instance, the name C augmented seventh, and the corresponding symbol Caug7, or C+7, are both composed of
parts 1, 2, and 3.
All this parts, except for the root, do not directly refer to the notes forming the chord, but to the intervals they form
with respect to the root. For instance, Caug7 is formed by the notes C-E-G-B. However, its name and symbol refer
only to the root note C, the augmented (fifth) interval from C to G, and the (minor) seventh interval from C to B. A
set of decoding rules is applied to deduce the missing information.
Although they are used occasionally in classical music, these names and symbols are "universally used in jazz and
popular music",[1] usually inside lead sheets, fake books, and chord charts, to specify the harmony of compositions.
Other notation systems for chords include:[2]
plain staff notation, used in classical music, Roman numerals,
commonly used in harmonic analysis,[3]figured bass, much used in the Baroque era, and macro symbols, sometimes
used in modern musicology.
Advantages and limitations
Any chord can be denoted using staff notation, showing not only its harmonic characteristics but also its exact
voicing. However, this notation, frequently used in classical music, may provide too much information, making
improvisation difficult. In fact, although voicings can and do have a significant effect on the subjective musical
qualities of a composition, generally these interpretations retain the central characteristics of the chord. This provides
an opportunity for improvisation within a defined structure and is important to improvised music such as jazz. Other
problems are that voicings for one instrument are not necessarily physically playable on another (for example, the
thirteenth chord, played on piano with up to seven notes, is usually played on guitar as a 4- or 5-note voicing that is
impossible to play on piano with one hand).
As a result of these limitations, a shorthand describing the harmonic characteristics of chords is used in pop music
and jazz. This notation has an advantage of being more easily expressed in plain text and in handwriting than the
relatively complicated process of writing chords on a staff. It is also faster to read.
The first part of a symbol for a chord defines the root of the chord. The root of the chord will always be played by
one of the instruments in the ensemble (usually by a bass instrument) failure to include the root means that the
indicated chord is not being played. By convention, the root alone indicates a simple major triad, i.e., the root, the
major third, and the perfect fifth above the root. After this, various additional symbols are added to modify this
chord. There is unfortunately no universal standard for these symbols. The most common ones are presented here.
Jazz and pop notation does not easily provide for ways of describing all chords. Some chords can be very difficult to
notate, and others that exist theoretically are rarely encountered. For example, there are 6 possible permutations oftriads (chords with three notes) involving minor or major thirds and perfect, augmented, or diminished fifths.

However, conventionally only four are used (major, minor, augmented and diminished). There is nothing to stop a
composer using the other two, but the question of what to call them is interesting. A minor third with an augmented
fifth might be denoted, for example, by Am+, which will strike most musicians as odd. In fact, this turns out to be the
same as F/A (see slash chords below). A major third with a diminished fifth might be shown as A(5).
Usually, when composers require a chord that is not easily described using this notation, they will indicate the
required chord in a footnote or in the header of the music.
Chord quality
Chord qualities are related with the qualities of the component intervals which define the chord (see below). 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:
m, or min for minor, M, maj, or no symbol (see rule 2 below) for major,
aug for augmented,
dim for diminished.
In addition, however,
is sometimes used for major,[4]
instead of the standard M, or maj,
is sometimes used for minor, instead of the standard m or min,
+, or aug, is used for augmented (A is not used),
o, , dim, is used for diminished (d is not used),
, or
is used for half diminished,
dom is used for dominant.
Chord qualities are sometimes omitted (see below).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 Cm/M7 (minor major
seventh chord), m is the chord quality and M refers to the M7 interval.
Major, minor, augmented, and diminished chords
3-note chords are called triads. There are four basic triads (major, minor, augmented, diminished), and they are alltertian, i.e. defined by the root, a third interval, and a fifth interval. Since most other chords are obtained 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:
C+7 = C+ + m7
augmentedchord augmentedtriad minor
interval
In this case, the quality (minor, in the example) of the additional interval is omitted. Less often, the full name or
symbol of the additional interval 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:

augmentedchord augmentedtriad major
interval
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, as the chord qualities "half-diminished", and "dominant" refer not only to the quality of the basic
triad, but also to 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), and a diminished triad 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 (M5
, M+5
, majaug5
). Similarly, the diminished triad can be named minor triad
flat five, or minor triad diminished fifth (m5, m5, 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, CM75,
or Cmaj7aug5
:
CM7+5 = C + M3 + A5 + M7
augmentedchord chord
root
major

augmentedinterval major

(In chord symbols, the symbol A, used for augmented intervals, is typically replaced by + or )
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 (G), rather than a perfect fifth from root (G). All chord names and symbols including altered fifths, i.e.
augmented (5, +5, aug5) or diminished (5, 5, dim5) fifths can be interpreted in a similar way.
Rules to decode chord names and symbols
The amount of information provided in a chord name or symbol lean toward the minimum, to increase efficiency.
However, it is often necessary to deduce from a chord name or symbol the component intervals which define the
chord. The missing information is implied and must be deduced according to some conventional rules:
1. General rule to interpret existing information about chord quality
For triads, major or minor always refer to the third interval, while augmented and diminished always refer to
the fifth. The same is true for the corresponding symbols (e.g., Cm means Cm3, and C+ means C+5). Thus, the
terms third and fifth and the corresponding symbols 3 and 5 are typically omitted.
This rule can be generalized to all kinds of chords,[5] provided the above mentioned qualities appear
immediately after the root note, or at the beginning of the chord name or symbol. For instance, in the chord
symbols Cm and Cm7, m refers to the interval m3, and 3 is omitted. When these qualities 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 Cm/M7 (minor-major seventh chord), m is the chord
quality and refers to the m3 interval, while M refers to the M7 interval. When the number of an extra interval
is specified immediately after chord quality, the quality of that interval may coincide with chord quality (e.g.CM7 = CM/M7). However, this is not always true (e.g. Cm6 = Cm/M6, C+7 = C+/m7, CM11 = CM/P11).

See specific rules below for further details.
2. General rule to deduce missing information about chord quality
Without contrary information, a major third interval and a perfect fifth interval (major triad) are implied. For
instance, a C chord is a C major triad, and the name C minor seventh (Cm7) implies a minor 3rd by rule 1, a
perfect 5th by this rule, and a minor 7th by definition (see below). This rule has one exception (see the first
specific rule below).3. Specific rules
When the fifth interval is diminished, the third must be minor.[6] This rule overrides rule 2. For instance,
Cdim7 implies a diminished 5th by rule 1, a minor 3rd by this rule, and a diminished 7th by definition (see
below).
Names and symbols which contain only a plain interval number (e.g. Seventh chord) or the chord root and a
number (e.g. C seventh, or C7) are interpreted as follows:
If the number is 2, 4, 6, etc., the chord is a major added tone chord (e.g. C6 = CM6 = Cadd6) and
contains, together with the implied major triad, an extra major 2nd, perfect 4th, or major 6th (see below).
If the number is 7, 9, 11, 13, etc., the chord is dominant (e.g. C7 = Cdom7) and contains, together with
the implied major triad, one or more of the following extra intervals: minor 7th, major 9th, perfect 11th,
and major 13th (see Seventh chords and Extended chords below).
For sixth chord names or symbols composed only of root, quality and number (such as "C major sixth", or
"CM6"):
M, maj, or major stands for major-major (e.g. CM6 means CM/M6),
m, min, or minor stands for minor-major (e.g. Cm6 means Cm/M6).
For seventh chord names or symbols composed only of root, quality and number (such as "C major seventh",
or "CM7"):
dom, or dominant stands for major-minor (e.g. Cdom7 means CM/m7),
M, maj, or major stands for major-major (e.g. CM7 means CM/M7),
m, min, or minor stands for minor-minor (e.g. Cm7 means Cm/m7),
+, aug, or augmented stands for augmented-minor (e.g. C+7 means C+/m7),
o, dim, or diminished stands for diminished-diminished (e.g. C
o7 means C
o/
o7),
, or half-diminished stands for diminished-minor (e.g. C7 means Co/m7).
Other specific rules for extended and added tone chords are given below.
Examples
The table shows the application of these generic and specific rules to interpret some of the main chord symbols. The
same rules apply for the analysis of chord names. A limited amount of information is explicitly provided in the chordsymbol (boldface font in the column labeled "Component intervals"), and can be interpreted with rule 1. The rest is
implied (plain font), and can be deduced by applying the other rules. The "Analysis of symbol parts" is performed by
applying rule 1.

Intervals
A chord consists of two or more notes played simultaneously that are certain intervals apart with respect to the chord
root. The following table shows the labels given to these intervals and the respective notes for each of the twelve
keys. As explained above, chord notation provides a shorthand for intervals, not actual notes. This table provides a
mapping of intervals to actual notes to play.

Triads
As earlier suggested, the root written alone indicates a simple major triad. It consists of the root, the major third, and
the perfect fifth above the root. Minor triads are the same as major triads, but with the third lowered by a half step.
Augmented triads are the same as a major triad, but with an augmented fifth instead of a perfect fifth. Diminished
triads are similar to minor triads, but with a diminished fifth instead of a perfect fifth (the minor third is retained).
The table below shows names, symbols and definition for the four kinds of triads (using C as root).

Seventh chords
A seventh chord is a triad with an added note, which is either a major seventh above the root, a minor seventh above
the root (flatted 7th), or a diminished seventh 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. When not otherwise specified, the
name "seventh chord" may more specifically refer to a major triad with an added minor seventh (a dominant seventh
chord).

Many possible format variations are possible. The superscripts may be also written as ordinary font, sometimesseparated by a slash from the preceding parts of the symbol, or written within parentheses. For instance:
CM7 may be written CM7
CmM7
may be written as CmM7, Cm/M7, or Cm(M7).
Except for the root, all the other parts of the symbols may be superscripted. For instance:
CM7 may be written CM7
CM75 may be written CM75, or CM75.
Some 7th chords can be considered as triad chords with alternate bass. Examples:
Cm7 = C-E-G-B = E/C
Cmaj7 = C-E-G-B = Em/C

Extended chords
Extended chords add further notes onto 7th chords. Of the 7 notes in the major scale, a seventh chord uses only 4.
The other 3 notes 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.
The 9th, 11th and 13th chords are known as extended tertian chords. As the scale repeats for every seven notes in the
scale, these notes are enharmonically equivalent to the 2nd, 4th, and 6th 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 9th, 11th and 13th in chord notation implies that the chord is an
extended tertian chord rather than an added chord (see Added Chords below).
9ths
9th chords are built by adding to a seventh chord a note which is an interval of a ninth from root. This implies that
the 7th note from root is also included in the chord. When the 7th is omitted, the chord cannot be classified as an
extended chord, as it becomes an added tone chord. 9ths may be theoretically added to any type of chord, however
they are most commonly seen with Major, Dominant and Minor sevenths.
The most commonly omitted note for voicings is the perfect 5th.

11ths
These are theoretically 9th chords with the 11th (4th) note in the scale added. However, it is common to leave certain
notes out. The major 3rd is often omitted because of a strong dissonance with the 11th (4th), therefore called an
avoid note. Omission of the 3rd reduces an 11th chord to the corresponding 9sus4 (suspended 9th chord; Aiken
2004, p. 104). Similarly, omission of the 3rd as well as 5th in C11 results in a major chord with alternate base B/C,
which is characteristic in soul and gospel music. For instance:

If the 9th is omitted, the chord is no longer an extended chord, but an added tone chord (see below). Without the 3rd,
this added tone chord becomes a 7sus4 (suspended 7th chord). For instance:

Alterations from the natural diatonic chords can be specified as C911 etc. Omission of the 5th in a sharped11th
chord reduces its sound to a flat-five chord. (Aiken 2004, p. 94):
C911 = C-E-(G)-B-D-F C-E-G-B-D = C95
13ths
These are theoretically 11th chords with the 6th note in the scale added. Again it is common to leave certain notes
out. After the 5th, the most commonly omitted note is the troublesome 11th (4th). The 9th (2nd) can also be omitted.
A very common voicing on guitar for a 13th chord, for example, is just the root, 7th, 3rd and 13th (6th). For
example: C-E-(G)-B-(D)-(F)-A = C-E-A-B-(D)-(F) - on the piano it is usually voiced C-Bb-E-A.

Alterations from the natural diatonic chords can be specified as C1113 etc.
Added tone chords
An important characteristic of jazz is the extensive use of sevenths. The combination of 9th (2nd), 11th (4th) and
13th (6th) notes with 7ths in a chord give jazz chord voicing their distinctive sound. However the use of these notes
is not exclusive to the jazz genre; in fact they are very commonly used in folk, classical and popular music generally.
Without the 7th, these chords lose their jazzy feel, but can still be very complex. These chords are called added tone
chords because they are basic triads with notes added. They can be described as having a more open sound than
extended chords. Notation must provide some way of showing that a chord is an added tone chord as opposed to
extended. There are two ways this is shown generally, and it is very common to see both methods on the same score.
One way is to simply use the word 'add', for example:
Cadd9
The second way is to use 2 instead of 9, implying that it is not a 7th chord for instance:
C2
Note that in this way we potentially get other ways of showing a 9th chord:
C7add9
C7add2
C7/9
Generally however the above will be shown as simply C9, which implies a 7th in the chord. Added tone chord
notation is useful with 7th chords to indicate partial extended chords. For example:
C7add13
This would indicate that the 13th is added to the 7th, but without the 9th and 11th.
The use of 2, 4 and 6 as opposed to 9, 11 and 13 pretty safely indicates that the chord does not include a 7th unless
specifically specified. However, it does not mean that these notes must be played within an octave of the root, northe extended notes in 7th 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 6th and 2nd notes of the scale added. These can be confusing because
of the use of 9, yet the chord does not include the 7th. A good rule of thumb is that if any added note is less than 7,
then no 7th is implied, even if there are some notes shown as greater than 7.
Similarly, even numbers such as 8, 10 and 12 can be added. However, these double the main triad, and as such are
fairly rare. 10 tends to be the most common; it can be used both in suspended chords and (with an accidental) in
major or minor chords to produce a major-minor clash (e.g. C7(10) indicating the Hendrix chord of C-E-E-G-B).
However, because of enharmonics, such chords can more easily, and perhaps more intuitively, be represented by 2
(or 9) for a minor over a major or 4 for a major over a minor. In any other case, an 8, 10 or 12 simply indicates the
respective note from the triad doubled up one octave.

Suspended Chords
A suspended chord is a triad where the 3rd is replaced by another note. In practice the 3rd is replaced either by the
4th or the 2nd. These are called suspended chords because they create an impression of suspense. These chords
"desire" to resolve into a normal triad. Suspended chords are notated with the symbols "sus4" or "sus2". Where "sus"
is found on its own, the suspended fourth chord is implied. This can be combined with any other notation. So for
example:
Csus9
This chord is an extended 9th chord with the 3rd replaced by the 4th (C-F-G-B-D). However, the major third can be
added as a tension above the 4th to "colorize" the chord (C-F-G-B-D-E). A sus4 chord with the added major third
(sometimes called a major 10th) can also be quartally voiced as C-F-B-E.
Power "chords"
Though power chords are not true chords per se, they 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 asfifth
chords, indeterminate chords or neutral chords (though the term "neutral chord," when expressed with an n (e.g.Cn), is also used to describe a pair of stacked neutral thirds, e.g. C-E -G, which requires a quarter tone or similarly
sized microtone; or the mixed third chord), 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.
In the event that an extended neutral chord is to be played, e.g. a seventh (C-G-B), 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, would be indicated C7no3.
Inversions
In addition to all of the ways of building chords (listed above), a chord may be inverted. Inverting a chord refers toplaying a chord, but with a note other than the root as the lowest note of the chord. Take, for example, the C Major
Chord. Refer to the table below for a list of inversions.
C Major Chord
Root Position First Inversion Second Inversion
C E G E G C G C E B C E G
Written as: C Written as: C/E Written as: C/G Written as: C7/B
The notation C/E indicates a C major chord, but with an E in the bass. Likewise the notation C/G indicates that a C
major chord is played with a G in the bass.
See figured bass for alternate method of notating specific notes in the bass.

Hybrid chords
Upper structures
Those are notated in a similar manner to inversions, except that the bass note is not necessarily a chord tone.
Examples:
C/A (A C E G), equivalent to A75;
C/E (E G C F);
Am/D (D A C E).
Chord notation in jazz usually leaves a certain amount of freedom to the player as for voicing chords, also adding
tensions at the player's discretion. Therefore, upper structures are most useful when the composer wishes for a
specific tension array to be played. Example:
C/E | C/A E/A | D/E G75/A | Eadd 2/D D79/G | Am7/C ||
produces a certain coloration of the following chord progression:
E7 | Am7 A7 | Em7 A7 | D G7 | C ||
These are also commonly referred as "slash chords." A slash chord (commonly used in Contemporary Christian
music) is simply a chord with the bass note replaced. For example:
D/F# is a D chord with the root bass note (D) replaced with F#;
A/C# is an A chord with the root bass note (A) replaced with C#.
Polychords
Polychords, as the name suggests, are combinations of two or more chords. The most commonly found form of a
polychord is a bi-chord (two chords played simultaneously) and is written as follows: (example: (C E
G B D F)). In case a very specific voicing is needed, the individual chords can be written in their desired
inversions, for example: (C G E G B E).
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.
For chord abbreviations, the right slash indicates the bass note if other than the root. It is usually written with the
complete chord name, and, after the slash symbol, the desired bass note. For example, the symbol C/G would meanthat the chord to play is a C major triad with a G as the bass note, leading to the following notes: G C E (commonly
known as the 2nd inversion C major triad).
A right slash surrounded by two dots reminiscent of a percent sign % [illustration needed] in an otherwise empty
measure indicates that the chord or chords of the previous measure are to be repeated. It can be reused over many
consecutive measures. It is used to simplify the job of both the reader (who can quickly scan ahead to the next chord
change) and the copyist (who doesn't need to write out the full chord symbols repeatedly).
The chord notation N.C. is used to indicate no chord is to be played. The duration of this symbol follows the same
rules as a regular chord symbol.

Summary
The description of chord notation has been as exhaustive as possible. Necessarily, in an attempt to be as complete as
possible, the description is lengthy, and not easy to decipher at a glance. This section is included as a brief summary
of one of the notations described, aimed more at the performer's perspective (rather than that of the composer or
theorist).
From the descriptions, above, it can be seen that C min maj 13 indicates a chord whose root is C, with each of the
odd intervals, up to the one indicated (13th in this case) placed above it, but with the 3rd flattened.
When the integer for the main interval is omitted, it is understood to be a 5
When the maj is omitted, it causes the 7th (if present) to be flattened
When the quality is min (as in the example above) the 3rd is flattened (as already stated)
When the quality is aug, the 5th is sharpened
When the quality is dim, each of the intervals is flattened
When the quality is sus or sus4, the third is sharpened
When the quality is sus2 the third is double-flattened
When the quality is omitted, none of them (min, aug, dim, sus, sus4 or sus2) is applied
In this way, C dim 9 indicates a chord whose root is C, with a flattened 3rd, a flattened 5th, a double-flattened 7th
(flattened once by the presence of dim, and flattened again by the omission of the maj) and a flattened 9th.
When a small even number is used as the main interval: 2 is equivalent to 9, 4 is equivalent to 11, and 6 is equivalent
to 13; but with the omission of the 7th possibly implied in each case; and when the number is explicitly stated as a 5,
it implies the omission of the 3rd.
In the vast majority of cases, though, none of this complexity is involved. A typical piece of music might stipulate
chords like C F Amin G7, giving (according to the summary above) two major triads, a minor triad, and an extended
chord of four notes.

[4] The symbol is ambiguous, as it is used by some as a synonym for M (e.g. C=CM and C7=CM7), and by others as a synonym of M7
(e.g. C=CM7).
[5] General rule 1 achieves consistency in the interpretation of symbols such as CM7, Cm6, and C+7. Some musicians legitimately prefer to
think that, in CM7, M refers to the seventh, rather than to the third. This alternative approach is legitimate, as both the third and seventh are
major, yet it is inconsistent, as a similar interpretation is impossible for Cm6 and C+7 (in Cm6, m cannot possibly refer to the sixth, which is
major by definition, and in C+7, + cannot refer to the seventh, which is minor). Both approaches reveal only one of the intervals (M3 or M7),
and require other rules to complete the task. Whatever is the decoding method, the result is the same (e.g., CM7 is always conventionally
decoded as C-E-G-B, implying M3, P5, M7). The advantage of rule 1 is that it has no exceptions, which makes it the simplest possibleapproach to decode chord quality.
According to the two approaches, some may format CM7 as CM7
(general rule 1: M refers to M3), and others as CM7
(alternative approach: M
refers to M7). Fortunately, even CM7
becomes compatible with rule 1 if it is considered an abbreviation of CMM7
, in which the first M is
omitted. The omitted M is the quality of the third, and is deduced according to rule 2 (see above), consistently with the interpretation of the
plain symbol C, which by the same rule stands for CM.
[6] All triads are tertian chords (chords defined by sequences of thirds), and a major third would produce in this case a non-tertian chord.
Namely, the diminished fifth spans 6 semitones from root, thus it may be decomposed into a sequence of two minor thirds, each spanning 3
semitones (m3 + m3), compatible with the definition of tertian chord. If a major third were used (4 semitones), this would entail a sequence
containing a major second (M3 + M2 = 4 + 2 semitones = 6 semitones), which would not meet the definition of tertian chord.
[7] Rarely used symbol. A shorter symbol exists, and is used more frequently.
