In music theory, the dominant seventh flat five chord is a seventh chord composed of a root note, together with a major third, a diminished fifth, and a minor seventh above the root (1, ♮ 3, ♭ 5 and ♭ 7). For example, the dominant seventh flat five chord built on G, commonly written as G 7♭5, is composed of the pitches G–B–D ♭ –F:
The dominant seventh chord on C. A seventh chord is a chord consisting of a triad plus a note forming an interval of a seventh above the chord's root. When not otherwise specified, a "seventh chord" usually means a dominant seventh chord: a major triad together with a minor seventh. However, a variety of sevenths may be added to a variety of ...
A tritone substitution is the substitution of one dominant seventh chord (possibly altered or extended) with another that is three whole steps (a tritone) from the original chord. In other words, tritone substitution involves replacing V 7 with ♭ II 7[ 7] (which could also be called ♭ V 7 /V, subV 7, [ 7] or V 7 / ♭ V [ 7] ).
Thickness-to-chord ratio. a=chord, b=thickness, thickness-to-chord ratio = b/a. The F-104 wing has a very low thickness-to-chord ratio of 3.36%. In aeronautics, the thickness-to-chord ratio, sometimes simply chord ratio or thickness ratio, compares the maximum vertical thickness of a wing to its chord. It is a key measure of the performance of ...
Similarly, this chord also occurs on the seventh degree of any natural minor scale (e.g., B ♭ 7 in C minor). The dominant seventh is perhaps the most important of the seventh chords. It was the first seventh chord to appear regularly in classical music. The V 7 chord is found almost as often as the V, the dominant triad, [5] and typically ...
In jazz. In jazz chords and theory, and classical music theory, the seventh is what defines a chord as a "seventh chord". Moreover, most triads that appear in lead sheets or fake books can have sevenths added to them, using the performer's discretion and "ear". For example, if a tune is in the key of C, if there is a G chord, the chord-playing ...
A chord chart (or chart) is a form of musical notation that describes the basic harmonic and rhythmic information for a song or tune. It is the most common form of notation used by professional session musicians playing jazz or popular music. It is intended primarily for a rhythm section (usually consisting of piano, guitar, drums and bass ).
The chord factor called the "fifth" (pitch name "G") is represented in voice 2 (shown in red). The chord factor that is in the bass determines the inversion of the chord. For example, if the third is in the bass it is a first inversion chord (figured bass: 6 3) while if the seventh is in the bass the chord is in third inversion (4 2). The ...
