THE DOMINANT SEVENTH CHORD Implications in Root Position

SEVENTH CHORD<br />

Implications<br />

in Root<br />

Position

DOMINANT SEVENTH CHORD (V 7 )<br />

• Consists of a major triad with a minor seventh (Mm7)<br />

• In this construct is a dissonant tritone and a minor seventh<br />

• In minor keys the third of the chord (leading tone) must be<br />

raised and indicated by figured bass accidental in Roman<br />

numeral analysis<br />

• V 7 is a four-tone chord; all tones may be present<br />

• Often the root is doubled and the fifth is omitted

DOMINANT SEVENTH CHORD (V 7 )<br />

• All rules attributed to connecting I – V apply with the<br />

following observations:<br />

• //8 and //5 should be avoided<br />

• P5 - °5 is permitted, as long as the diminished fifth is subsequently<br />

resolved.

VOICE LEADING V 7 - I<br />

• Determined by the need to resolve with dissonant intervals<br />

• Third and <strong>Seventh</strong> of the V 7 are tendency tones and form a<br />

tritone which must be resolved using the following method<br />

• Normal resolution of seventh is stepwise downward<br />

• <strong>The</strong> leading tone resolves stepwise to the tonic<br />

• <strong>The</strong> root of the V 7 moves to the root of tonic<br />

• Strict resolution of the V 7 – in an incomplete V 7 the doubled<br />

root remains stationary; incomplete=double root, no fifth

VOICE LEADING V 7 - I<br />

• <strong>The</strong> following explanation relates to each chord respectively<br />

• 7 – 3<br />

• 3 – root<br />

• Root - root<br />

Keep common tones in the same voice if possible.

COMPLETE V 7 CHORDS<br />

• Complete V 7 contain all four voices (root – 3 rd – 5 th – 7 th )<br />

• After the tritone of a complete V 7 chord is resolved, the fifth<br />

will be omitted and the root tripled in the I chord.<br />

A complete V 7 chord resolves to an<br />

incomplete tonic (5 th omitted)

INCOMPLETE V 7 CHORDS<br />

• Incomplete V 7 chords lack the chordal 5 th<br />

• Typically the root is doubled<br />

• Resolve the tritone as usual<br />

• Move the root of the V 7 to the root of the tonic<br />

• Maintain a common tone.<br />

An incomplete V 7 chord (5 th omitted)<br />

will resolve to a complete tonic chord<br />

(doubled root, 3 rd , and 5 th )

FREE RESOLUTION OF THE LEADING TONE<br />

• This will ONLY occur if the leading tone is in an inner voice<br />

(tenor or alto).<br />

• <strong>The</strong> leading tone may skip down a third to the fifth of the<br />

tonic – making both chords complete

EXERCISES<br />

Resolve the following V 7 chords in the given voicing. Indicate the tritone with<br />

brackets and resolve using rules for strict resolution.

EXERCISES<br />

Resolve the following V 7 chords with the given voicing. Indicate the tritone with<br />

brackets. Resolve the leading tone or chord seventh freely.
