"A chord, in music, is any harmonic set of pitches or frequencies consisting of multiple notes (also called "pitches") that are heard simultaneously, or nearly so."
Understanding different types of chords and how they can be constructed. This includes triads, seventh chords, and extended chords.
Intervals: The distance between any two notes.
Triads: Three-note chords that are the building blocks of harmony.
Chord Progressions: A series of chords played one after another.
Inversions: Playing a chord with the notes in a different order.
Seventh Chords: Four-note chords containing a root, third, fifth and seventh.
Extended Chords: Chords containing more than four notes.
Major and Minor Chords: Different types of chords that create different moods.
Diminished and Augmented Chords: Unusual chords that create tension and dissonance.
Transposing: Playing a song in a different key.
Roman Numeral Analysis: A system for understanding chord progressions and their relationships to each other.
Cadences: The last two chords in a chord progression that signal the end of a phrase or song.
Major Chord- A major chord is made up of three notes: The root, major third, and perfect fifth. It sounds “happy” and is often used in pop, rock, and country music.
Minor Chord- A minor chord is made up of three notes: The root, minor third, and perfect fifth. It sounds “sad” and is often used in classical, jazz, and blues music.
Augmented Chord- An augmented chord is made up of three notes: The root, major third, and augmented fifth. It sounds “tense” and is often used in jazz and classical music.
Diminished Chord- A diminished chord is made up of three notes: The root, minor third, and diminished fifth. It sounds “ominous” and is often used in jazz and classical music.
Seventh Chord- A seventh chord is made up of four notes: The root, third, fifth, and seventh. There are several different types of seventh chords, including major seventh, minor seventh, dominant seventh, and half-diminished seventh.
Suspended Chord- A suspended chord is made up of three notes: The root, second, and fifth. It sounds “ambiguous” and is often used in pop and rock music.
Power Chord- A power chord is made up of two notes: The root and fifth. It sounds “heavy” and is often used in heavy metal and punk music.
"For many practical and theoretical purposes, arpeggios and other types of broken chords (in which the chord tones are not sounded simultaneously) may also be considered as chords in the right musical context."
"In tonal Western classical music (music with a tonic key or 'home key'), the most frequently encountered chords are triads, so called because they consist of three distinct notes: the root note, and intervals of a third and a fifth above the root note."
"Chords with more than three notes include added tone chords, extended chords, and tone clusters, which are used in contemporary classical music, jazz, and almost any other genre."
"A series of chords is called a chord progression."
"One example of a widely used chord progression in Western traditional music and blues is the 12 bar blues progression."
"Although any chord may in principle be followed by any other chord, certain patterns of chords are more common in Western music."
"To describe this, Western music theory has developed the practice of numbering chords using Roman numerals to represent the number of diatonic steps up from the tonic note of the scale."
"Common ways of notating or representing chords in Western music (other than conventional staff notation) include Roman numerals, the Nashville Number System, figured bass, chord letters, and chord charts."
