{{disambiguation}}
The triad formed using the C note as the root would consist of C(root), E(third) and G(fifth), and these comprise a C major chord (the designation major denotes the fact that the E is four semitones ] higher than the root note.

http://meta.wikipedia.com/upload/c_triad.png ''Fig 2. C, E and G - The C major triad''

Using the same scale (and thus, implicitly, the key of C major) a chord may be constructed using the D as the root note. This would be D(root), F(third), A(fifth), which comprise the chord of D ], since the third, F, is a ''minor'' third (three semitones) higher than the root.

=== Types of triads ===

As well as major and minor, there can also be ''augmented'' and ''diminished'' triads. Augmented triads are composed of a major 3rd but an augmented 5th (meaning the top note has been increased by one semitone.) Diminished triads have a minor 3rd and a diminished 5th (same as a minor triad, except the top note has been lowered by a semitone.) These rules summarise the type of triads encountered so far:

*Major triad: root, major 3rd, perfect 5th
*Minor triad: root, minor 3rd, perfect 5th
*Augmented triad: root, major 3rd, augmented 5th
*Diminished triad: root, minor 3rd, diminished 5th

Some chords constructed from the notes of the C major scale:
: E G B -- E minor
: F A C -- F major
: G B D -- G major
: A C E -- A minor
: B D F -- B diminished

⚫ === Naming ===

Triads are sometimes named using roman numerals after their position in the scale of the key of the piece. For example in the key of C major any triad with C as its root is named I. A triad beginning on a E (the third note of the scale of C major) would be named III etc... Written in lowercase next to the roman numeral of the triad is its particular ] (a description of which notes have been moved up an octave.) A ''first inversion'' triad has an 'a' in its name (eg. the first inversion of chord V is Va.) A ''second inversion'' triad has a 'b', and a ''third inversion'' triad has a c.

Patterns with the type of chords found in major keys can be seen when using this naming scheme:

*In a major key, the major triads are: I, IV, V
*In a major key, the minor triads are: II, III, VI
*In a major key, the triad on VII is diminished
