Dream chord on G Play ⓘ.. The dream chord is a chord that is used prominently in the works of La Monte Young.It is made up of the pitches G-C-C♯-D. [2] [3] The chord is prominently featured in Young's compositions for Brass (1957), Trio for Strings (1958), and The Four Dreams of China (1962).
For example, if a tune is in the key of C, if there is a G chord, the chord-playing performer will usually "voice" this chord as G7. While in a strict classical music context, the notes of a G7 chord would be "G–B–D–F", in jazz, the fifth of the chord is often omitted. The root is also often omitted if playing in a jazz group, as it will ...
Though power chords are not true chords per se, as the term "chord" is generally defined as three or more different pitch classes sounded simultaneously, and a power chord contains only two (the root, the fifth, and often a doubling of the root at the octave), power chords are still expressed using a version of chord notation.
This chord, sometimes called a leading-tone diminished seventh chord, is represented by the Roman numeral notation vii ø 7, the root of which is the leading-tone to the tonic. [3] In the key of C, this is chord is B ø 7, as shown below.
The major seventh chord, sometimes also called a Delta chord, can be written as maj 7, M 7, Δ, ⑦, etc. The "7" does not have to be superscripted, but if it is, then any alterations, added tones, or omissions are usually also superscripted. For example, the major seventh chord built on C, commonly written as Cmaj 7, has pitches C–E–G–B:
In popular music and rock music, "borrowing" of chords from the parallel minor of a major key is commonly done. As such, in these genres, in the key of E major, chords such as D major (or ♭ VII), G major (♭ III) and C major (♭ VI) are commonly used. These chords are all borrowed from the key of E minor.
Diminished seventh chords may also be rooted on scale degrees other than the leading-tone, either as secondary function chords temporarily borrowed from other keys, or as appoggiatura chords: a chord rooted on the raised second scale degree (D ♯ –F ♯ –A–C in the key of C) acts as an appoggiatura to the tonic (C major) chord, and one ...
The most common chords are tertian, constructed using a sequence of major thirds (spanning 4 semitones) and/or minor thirds (3 semitones). Since there are 3 third intervals in a seventh chord (4 notes) and each can be major or minor, there are 7 possible permutations (the 8th one, consisted of four major thirds, results in a non-seventh augmented chord, since a major third equally divides the ...
