chord

chord, in music, three or more single pitches heard simultaneously. Depending on the harmonic style, chords may be consonant, implying repose, or dissonant, implying subsequent resolution to and by another chord.

: a group of three or more tones sounded together to form harmony. chordal. -əl. adjective. chord.

key, in music, a system of functionally related chords deriving from the major and minor scales, with a central note, called the tonic (or keynote). The central chord is the tonic triad, which is built on the tonic note. Any of the 12 tones of the chromatic scale can serve as the tonic of a key.

In traditional Western harmony, chords are formed by superimpositions of intervals of a third. Thus, the basic triad results from the superimposition of two conjunct thirds encompassing the interval of a fifth; for example, e–g (a minor third) superimposed on c–e (a major third) yields the triad c–e–g.

chord/ cord Chord and cord sound the same, but a chord is three or more notes played together while a cord is basically a thick string. You strum a chord, but you tie a cord. Just remember that the letter “h” is like the extra note you need to make a chord.

Key takeaways

• Major and minor chords are the two basic chords in music.
• A major chord consists of a major third, followed by a minor third.
• A minor chord consists of a minor third, followed by a major third.
• You can easily build these chords by skipping every other note on the keyboard.

In Euclidean geometry, the intersecting chords theorem, or just the chord theorem, is a statement that describes a relation of the four line segments created by two intersecting chords within a circle. It states that the products of the lengths of the line segments on each chord are equal.

Triads Triads. This is the most common chord structure that contains three notes, most commonly the root note, third, and fifth or dominant of the key. If we look at a c major chord, we will find a triad of C E and G. A C minor chord consists of C Eb and G.

How To Read Chord Charts

1. The vertical lines represent your strings from lowest on the left (Low E) to highest on the right (High E).
2. The horizontal lines represent the frets on a guitar neck.
3. “X” means closed.
4. “O” means open.
5. The dots on the frets indicate where you should put your fretting hand.

The 4 basic chord types are:

• Major Chords. Major chords sound full, resolved and complete.
• Minor Chords. Here's the good news.
• Diminished Chords. Diminished chords will add a tense, dissonant sound to your music.
• Augmented Chords.
