A guitarist performing a C chord with G bass. In Western music theory, a chord is a group [a] of notes played together for their harmonic consonance or dissonance.The most basic type of chord is a triad, so called because it consists of three distinct notes: the root note along with intervals of a third and a fifth above the root note.

Two-note chords are called dyads, three-note chords built by using the interval of a third are called triads. Arpeggiated chord A chord with notes played in rapid succession, usually ascending, each note being sustained as the others are played. It is also called a broken chord, a rolled chord, or an arpeggio.
The perfect-fifth interval is called a power chord by guitarists, who play them especially in blues and rock music. [7] [8] The Who's guitarist, Peter Townshend, performed power chords with a theatrical windmill-strum. [7] [9] Power chords are often played with the notes repeated in higher octaves. [7]
In this case, the chord is viewed as a C major seventh chord (CM 7) 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, o 5, dim5) fifths can be interpreted in a similar way.
In music theory, a major chord is a chord that has a root, a major third, and a perfect fifth. When a chord comprises only these three notes, it is called a major triad . For example, the major triad built on C, called a C major triad, has pitches C–E–G:
The "A" type barre chord, occasionally called the double barre, is the A chord shape (X02220) moved up and down the frets. To barre the A chord shape, the guitarist puts the index finger across the top five strings, usually touching the 6th string (E) to mute it.
The key note, or tonic, of a piece of music is called note number one, the first step of (here), the ascending scale iii–IV–V. Chords built on several scale degrees are numbered likewise. Thus the chord progression E minor–F–G can be described as three–four–five, (or iii–IV–V). A chord may be built upon any note of a musical scale.
