Major chords

Major chords are the most common chords for the piano and other instruments. The major chord names are written in sole letters like C, D, E and so forth; otherwise, the abbreviation for major in chord names is maj. Besides the main chord category, there are also Major 7th chords (maj7), Major 9th chords (maj9) and Major 6th chords (6) among others.

Theory

A major triad includes three notes and these can be referred to as the root, major third and perfect fifth. To explain it in plain English, this means that the notes in the chord are the first, the third and the fifth notes in the related scale.

We can compare the C Major Scale with the C Major Chord:

C Major Scale: C – D – E – F – G – A – B
C major scale

C Major Chord: C – E – G
C major chord

Formula and steps

A good way to minimize the memorizing are to learn formulas. The formula for a minor chord is 1 - 3 - 5, which refers to the major scale degrees.

You could also learn by steps. From the 1st note go four half steps to the right to the 2nd note, and from the 2nd note go three steps to the right to the 3rd note.

Other major chords

Let us continue with major 7 chords that are built by adding the seventh note in the related scale.

Comparing the C Major Scale with the C Major 7 Chord:

C Major Scale: C – D – E – F – G – A – B
C Major 7 Chord: C – E – G – B

There are also Major 6th chords with the sixth note in the scale added to a triad. These are, however written without the abbreviation "maj" and sometimes this category is called added 6th.

Comparing the C Major Scale with C6:

C Major Scale: C – D – E – F – G – A – B
C6 Chord: C – E – G – A

The idea is the same for major 9 chords in which the ninth note is added. The C Major 9 chord is accordingly look like this: C – E – G – B – D. This chord category is somewhat unusual and there are no diagrams of these chords on the site so far.

Although rather unusual, an additional group to know about is Major ninth (maj9). This chord is built by adding a major ninth to a major seventh chord. Maj9 not to be confused with the dominant 9th.

Comparing the C Major Scale with Cmaj9:

C Major Scale: C – D – E – F – G – A – B
C Major 9 Chord: C – E – G – B – D

Also to mention is maj9#11
Cmaj9#11: C – E – G – B – D – F#

Even less common is the Major thirteenth (maj13), built by adding a 13th. This chord includes seven notes, but to make it more practical some notes (the least important for the chord color, which especially include the eleventh) are normally left out. Maj13 not to be confused with the dominant 13th.

Comparing the C Major Scale with Cmaj13:

C Major Scale: C – D – E – F – G – A – B
C Major 13 Chord: C – E – G – B – D – A

Alternative chord symbols

Besides the major chord symbol that is presented on this site, you may find alternatives, including the following instead of C:

CMaj (relative common symbol there “Maj” is written out as the abbreviation for major)
C△ (the triangle is sometimes used in piano sheets as a symbol for major)
CM (here a capital letter is being used for “major”, which are not recommended due to the possible confusing with a “minor” symbol)

CM7 or C△7 are alternative chord names used instead for Cmaj7 (the triangle is sometimes also used in piano sheets as a single symbol for major seventh).

CM9 or C△9 are alternative chord names used instead for Cmaj9, CM11 or C△11 are alternative chord names used instead for Cmaj11 and CM13 or C△13 are alternative chord names used instead for Cmaj13.

CM6 is an alternative chord name sometimes used instead for C6.
