Chord notation
open-in-new
<p>Musicians use various kinds of chord names and symbols in different contexts to represent <a href="/facts/Chord_(music)/hJBCHCSB">musical chords</a>. In most <a href="/facts/List_of_popular_music_genres/71QvB5AR">genres</a> of <a href="/facts/Popular_music/Q5yhxIwY">popular music</a>, including <a href="/facts/Jazz/lmUzXGq8">jazz</a>, <a href="/facts/Pop_music/kgshFE5B">pop</a>, and <a href="/facts/Rock_music/zBM2guyQ">rock</a>, a chord name and its corresponding symbol typically indicate one or more of the following: </p> <ul><li>the <a href="/facts/Root_(chord)/BzI7uzCG">root note</a> (e.g. C♯)</li> <li>the chord quality (e.g. <a href="/facts/Minor_chord/XdLGImHS">minor</a> or lowercase m, or the symbols o or + for diminished and augmented chords, respectively; chord quality is usually omitted for major chords)</li> <li>whether the chord is a <a href="/facts/Triad_(music)/YIA2T6Y6">triad</a>, <a href="/facts/Seventh_chord/XeWsnNrL">seventh chord</a>, or an <a href="/facts/Extended_chord/83h8ttwM">extended chord</a> (e.g. Δ7)</li> <li>any <a href="/facts/Altered_note/mrgwXrxw">altered notes</a> (e.g. <a href="/facts/Augmented_fifth/Dhc8Xn3p">sharp five</a>, or ♯5)</li> <li>any <a href="/facts/Added_tone_chord/e1Dp4dLA">added tones</a> (e.g. <a href="/facts/Added_tone_chord/e1Dp4dLA">add2</a>)</li> <li>the <a href="/facts/Bass_note/WgrYFa8L">bass note</a> if it is not the root (e.g. a <a href="/facts/Slash_chord/yCter4pS">slash chord</a>)</li></ul> Macro analysis symbols<table><tbody><tr><th>Triad</th><th>Root</th><th>Quality</th><th>Example</th><th>Audio</th></tr><tr><th><a href="/facts/Major_chord/RwuuqKYS">Major triad</a></th><td>Uppercase</td><td></td><td>C</td><td></td></tr><tr><th><a href="/facts/Minor_chord/XdLGImHS">Minor triad</a></th><td>Lowercase</td><td></td><td>c</td><td></td></tr><tr><th><a href="/facts/Augmented_triad/2R7MpG0C">Augmented triad</a></th><td>Uppercase</td><td>+</td><td>C+</td><td></td></tr><tr><th><a href="/facts/Diminished_triad/M5G6mgsu">Diminished triad</a></th><td>Lowercase</td><td>o</td><td>co</td><td></td></tr><tr><th><a href="/facts/Dominant_seventh_chord/E4EIVqmN">Dominant seventh</a></th><td>Uppercase</td><td>7</td><td>C7</td><td></td></tr></tbody></table> <p>For instance, the name <a href="/facts/Augmented_seventh_chord/wpbvNpcR">C augmented seventh</a>, and the corresponding symbol Caug7, or C+7, 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–G♯–B♭. The three parts of the symbol (C, aug, and 7) refer to the root C, the <a href="/facts/Augmented_fifth/Dhc8Xn3p">augmented (fifth)</a> interval from C to G♯, and the <a href="/facts/Minor_seventh/Aa7YIt0e">(minor) seventh</a> interval from C to B♭. </p><p>Although they are used occasionally in <a href="/facts/Classical_music/oglVXmSb">classical music</a>, typically in an educational setting for <a href="/facts/Harmony/Uwagvon2">harmonic analysis</a>, these names and symbols are "universally used in jazz and popular music", in <a href="/facts/Lead_sheet/790UPN2U">lead sheets</a>, <a href="/facts/Fake_books/790UPN2U">fake books</a>, and <a href="/facts/Chord_chart/FPBJXaMv">chord charts</a>, to specify the <a href="/facts/Chord_(music)/hJBCHCSB">chords</a> that make up the <a href="/facts/Chord_progression/zrB3N8Fc">chord progression</a> of a <a href="/facts/Song/wm7uRPzQ">song</a> 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 </p> C – Am – Dm – G7. <p>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 <a href="/facts/Seventh_chord/XeWsnNrL">sevenths</a>, <a href="/facts/Ninth_chord/xLl5tnCr">ninths</a>, and higher <a href="/facts/Extended_chord/83h8ttwM">extensions</a> to the chord. In some pop, rock and folk genres, triads are generally performed unless specified in the chord chart. </p>
