|G Major Chord#Strumming|Strumming}}
In the key of C Major, G is the 5th note of the scale, and the G Major chord is thus called the ''<u>V chord'' </u> (that's the roman numeral five, not the letter 'v'). It's notes are the perfect 5th, major 7th, and major 9th (octave of the major 2nd) above the tonic note of the key ((G B D) for the key of C Major). ''Note: like all major chords, it consists of a root and the M3 and P5 above the root. G is the root; B is a M3 above G; D is a P5 above G.''
The V Chord is unambiguously a <u>dominant function</u> chordThat last paragraph was probably quite confusing. This means Rather than try to do all the distance math in our heads, it produces a large amount of tension and "wants" 's simpler to resolve to a tonic-function chord. The 7th note say that the root of the major scale V chord is called the leading tone because it naturally "wants" to resolve up a half step to P5 above the tonic note. The B note in , and that the G V chord is a major chord . That is the leading tone of the key of C Major and wants enough to resolve a half-step up to Cquickly determine its member notes. The root note of And given that the V chord is also diatonic to the fifth major scale and that all basic triads consist of every other note from the I chordroot, making its transition from we can simply skip the V chord A and C to get (G B D). At this point it may be easier to simply memorize the I chord seamlessnotes. The G in Later, you'll see why the G chord becomes intervallic relationships matter, start to understand all the 5th of patterns, and see how multiple methodologies point to the C chord (C E G)same results.
The 5th of the V chord is the 9th or 2nd of the scale, which isn't in the I chord. For a C G chord, this is the B D note. - Notes It can descend one wholeB--1----8----12---15- |-P5-| \ |--step to -M7----| } distances from the root tonic note of the I chord (C) for a very peaceful resolution or ascend one wholeMajor key |------M9----step to --| / U \ |-M3-| } distances from the major 3rd root note of the I G major chord (E) for a richer harmony. |---P5----| /
This makes the The V Chord is unambiguously a <u>dominant function</u> chord ideal to lead into , also called the I chord. This is called an [[Music_Theory_-_Diatonic_Chord_Progressions#Authentic_Cadence|<u>authentic cadencedominant chord</u>]]. This means it produces a large amount of tension and "wants" to resolve to a tonic-function chord, which such as the harmonic equivalent I chord. The 7th note of the major scale is called the leading tone because it naturally "wants" to resolve up a half step to the tonic note . The B note in the G major chord is the leading tone of the key of C Major and wants to resolve up a half-step up to C. The root note of the V chord is also the fifth of the I chord, making its transition from the V chord to the I chord seamless. The G in melodythe G chord becomes the 5th of the C chord (C E G) without changing. However, it can alternatively descend from G to the E of C major. The 5th of the V chord is the 9th or 2nd of the scale, which isn't in the I chord. For a G chord, this is the D note. It is can descend one whole-step to the root note of the strongest way I chord (C) for a very peaceful resolution or ascend one whole-step to establish tonalitythe major 3rd of the I chord (E) for a richer harmony.
The V chord - I progression is also called the an [[Music_Theory_-_Diatonic_Chord_Progressions#Authentic_Cadence|<u>dominant chordauthentic cadence</u>]], which the harmonic equivalent of the leading tone to tonic note in melody. It is the strongest way to establish tonality, moving from the strongest tension to the strongest resolution.
