Example 13 shows two different seventh chords in open spacing with doublings. Two seventh chords with doublings in open spacing. Neither of these factors will affect how you identify these seventh chords. Simply imagine or write the notes of seventh chords in closed spacing without any doublings to identify these chords, as we did previously.
A seventh chord in which the triad quality is diminished and the seventh quality is minor. For example: B—D-F-A. Another name for a major-major seventh chord, a seventh chord with a major triad and a major seventh. A seventh chord in which the triad quality is major and the seventh quality is minor. Another name for a minor minor seventh chord, a seventh chord with a minor triad and a minor seventh. Another name for a fully diminished seventh chord, a seventh chord with a diminished triad and a diminished seventh.
When applied to an interval, the term "quality" modifies the size descriptor in order to be more specific about the exact number of semitones in the interval. When applied to triadic harmony, "quality" refers to the size of the different intervals that make up the harmony. Skip to content I. A seventh chord is a four-note chord whose notes can be arranged in thirds. When stacked in its most compact form in thirds, the lowest note of a seventh chord is called the root , the lower middle note is called the third , the upper middle note is called the fifth , and the highest note is called the chordal seventh.
There are five common qualities of seventh chord. These qualities are the major-major seventh chord , major-minor seventh chord , minor-minor seventh chord , half-diminished seventh chord , and the fully diminished seventh chord.
There is another common way of naming seventh chords: the major-major seventh chord is also often called the major seventh chord , the major-minor seventh chord is also often called the dominant seventh chord , the minor-minor seventh chord is also often called the minor seventh chord , and the fully diminished seventh chord is also often simply called the diminished seventh chord Within major and minor keys, seventh chords have particular qualities that correspond to scale-degrees.
These are the same in every major and minor key, which makes memorizing them useful. Seventh chords are identified by their root , quality of triad and chordal seventh, and inversion. A four-note chord whose pitch classes can be arranged as thirds. The lowest note of a triad or seventh chord when the chord is in root position.
The note of a triad or seventh chord a third above the root. The note of a triad or seventh chord a fifth above the root.
The C major triad: …spans from C to G: …which is a perfect fifth. C to G is an augmented fifth but, for all intents and purposes, is still a fifth. The C major seventh chord: …spans from C to B: …which is an interval of a major seventh.
Seventh chords have more width than triads because they have the width of a seventh while triads have the width of a fifth. Juice may be sweeter than water, but juice is made of water. This seventh chord can be broken down into two triads…. Therefore, they are called triadic components. Seventh chords may show harmonic advancement over triads in terms of texture and width but they are made up of triadic components.
Triads are the most basic form of harmony, however, stitching triads together will produce bigger chords known as polychords. C major and E minor triads are correlated to the C major seventh chord. Therefore, when the C major triad: …and the E minor triad: …are played together, the outcome: …is an overall major seventh chord. Triads and seventh chords are all harmony at different levels and none is absolute. Such situations require triads in their basic structure and seventh chords will not fit perfectly into the picture.
The same thing happens in music. A Seventh Chord is a four-note chord whose pitches can be arranged as thirds. Like with a triad, the pitches belonging to a seventh chord occupy adjacent positions a four-pitch-class clump on the circle of thirds. Also like a triad, we attribute names to each member of the chord. The four members of a seventh chord are named as: the root , third , fifth , and seventh.
There are four qualities of triads that appear in major and minor scales, each with their own characteristic intervals. A triad can be summed up by a single symbol, such as a lead-sheet chord symbol. A lead sheet symbol includes information about both root quality, as well as which pitch class occurs in the lowest voice called the bass regardless of who is singing or playing that pitch. A lead-sheet symbol begins with a capital letter and, if necessary, an accidental denoting the root of the chord.
Finally, if a pitch class other than the chord root is the lowest note in the chord, a slash is added, followed by a capital letter denoting the pitch class in the bass lowest voice. A C-minor triad is Cm.
And so on. Chords are often labeled according to their function within a key. Some musicians also use Roman numerals to describe the quality of the chord. Lower-case Roman numerals i, ii, iii, etc.
