The dominant 7 ♯ 11 or Lydian dominant (C 7 ♯ 11) comprises the notes: . r, 3, (5), ♭ 7, (9), ♯ 11, (13) (Note that in jazz lead sheet notation, upper extensions (intervals beyond the 7th) aren't named unless they are altered; alternatively, when including the 9th and 13th this chord could be called a C 13 ♯ 11.)
In Roman numeral analysis, G 7 would be represented as V 7 in the key of C major. This chord also occurs on the seventh degree of any natural minor scale (e.g., G7 in A minor). The dominant seventh is perhaps the most important of the seventh chords.
In the key of C major, the I major 7 chord is "C, E, G, B," the iii chord ("III–7" [11]) is E minor 7 ("E, G, B, D") and the vi minor 7 chord is A minor 7 ("A, C, E, G"). Both of the tonic substitute chords use notes from the tonic chord, which means that they usually support a melody originally designed for the tonic (I) chord.
the root note (e.g. C ♯) the chord quality (e.g. minor or lowercase m, or the symbols o or + for diminished and augmented chords, respectively; chord quality is usually omitted for major chords) whether the chord is a triad, seventh chord, or an extended chord (e.g. Δ 7) any altered notes (e.g. sharp five, or ♯ 5) any added tones (e.g. add2)
In jazz chords and theory, most triads that appear in lead sheets or fake books can have sevenths added to them, using the performer's discretion and ear. [1] For example, if a tune is in the key of C, if there is a G chord, the chord-playing performer usually voices this chord as G 7.
The accompaniment performers translate the Roman numerals to the specific chords that would be used in a given key. In the key of E major, the diatonic chords are: E maj7 becomes I maj7 (also I ∆7, or simply I) F ♯ m 7 becomes II m7 (also II −7, II min7, IIm, or II −) G ♯ m 7 becomes III m7 (also III −7, III min7, IIIm, or III −)
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 ...
Successive seventh chords starting with a secondary dominant: V 7 /V (II 7)–V 7 –I, in this case G 7 –C 7 –F). Note the chromatic voice leading (B ♮ –B ♭ –A), and that the F in the first chord is 27.26 cents lower than the F in the third chord. Play ⓘ barbershop seventh chord.
