Chapter 6 - Harmonic Organization 2: Chords in Diatonic Contex

chord

chord

When a(n) ________ is in second inversion, the intervals above the bass are a sixth and a fourth.

Subtonic

________ triad- The chord built on the seventh scale degree in natural minor.

V7 chord

The ________ is the same in major and harmonic minor.

lowercase Roman

Minor triads are indicated with ________ numbers.

Tonic

________ triad- The chord build on the ________ note (G) in G Major.

third inversion

A seventh chord in ________ has the seventh of the chord in the bass.

Tonic triad

The chord build on the tonic note (G) in G Major

Subtonic triad

The chord built on the seventh scale degree in natural minor

Figured bass

Consists of the bass line and the Arabic numbers under the bass line that represent the intervals above the bass to be played

Purpose of inversion symbols

To indicate the lowest-sounding note within a chord

harmonic function of a triad

related to the scale degree on which is built

Qualities of diatonic triads in a major key:

most used form for harmonizing in a minor key.

harmonic form of minor

Qualities of diatonic triads in harmonic minor:

Commonly used triads from natural minor:

• Major mediant (III)

• VII

• Subtonic

When we compare the qualities in the diatonic major and harmonic minor scales

the major chord and the diminished chord are of the same quality in both.

When a chord is in first inversion

• the note that is the interval of a sixth above the bass is the root.

• The inversion symbol is a superscript Arabic number 6 placed to the right of the Roman number.

When a chord is in second inversion

• the intervals above the bass are a sixth and a fourth.

• The note that is a fourth above the bass is the root.

• The inversion symbol is superscript 6/4 added to the Roman number chord symbols.

Seventh chord

Contains four notes. All of them are unstable because the arrangement of tones contains an interval of a seventh.

Notes of the seventh chord

• Root

• Third

• Fifth

• Seventh

• Five Basic Seventh Chords

• Major seventh (major triad + major seventh)

• Dominant seventh (major triad + minor seventh)

• Minor seventh (minor triad + minor seventh)

• Half-diminished seventh (diminished triad + minor seventh)

• Fully-diminished seventh (diminished triad + diminished seventh)

A seventh chord in first inversion

• has the third of the chord in the bass.

• The root of the chord is the interval of a sixth above the bass.

• The inversion symbol is 6/5.

A seventh chord in second inversion

• has the fifth of the chord in the bass.

• The root of the chord is the interval of a fourth above the bass, and the added seventh is a third above the bass.

• The inversion symbol is 4/3.

A seventh chord in third inversion

• has the seventh of the chord in the bass.

• The root of the chord is a second (the inversion of a seventh) above.

• The inversion is written as 4/2 or 2/1.

fully-diminished seventh chord

occurs on the leading tone in harmonic minor.

V7 chord occurs where

only occurs on the dominant.
