DOMINANT 7th, THE PREDOMINANT AREA

AND

CHORALE HARMONIZATION

* The dominant 7th chord, just like all of the 7th chords, is made up of four notes, and it can be inverted in three different ways. This chord is usually found just before the end of a phrase, and it is used to form cadence.

* When using the dominant 7th as a cadence, it has two tendency notes that have to be resolved, the chordal seventh and the leading tone. The chordal seventh resolves to the third and the leading tone to the first.

THE IMAGE BELOW SHOWS 

In the soprano part of bar 1, B, the leading-tone is resolved up by step to C, and in bar 2, B, the leading-tone is resolved down to G by a leap.
    
In the alto part of bar 1, F, the 7th degree is resolved down by step to E, and in bar 2, it follows the same pattern.

  In the tenor part of bar 1, B, the leading-tone is resolved up by step to C, and in bar 2, it follows the same pattern.




* The predominant chords are chords that resolve to the dominant they expand a basic-phrase into a predominant area. This area is set up as tonic-predominant-dominant-tonic or T-PD-D-T.

This is an example of how the predominant area is set up.




* Two most commonly used predominant chords are the second and fourth chords, these chords harmonies with the dominant in both major and minor keys.

* The predominant area expands when the I moves to chords such as the IV, ii first-inversion, or ii that can move to either V or the V7th and return the I chord in major-keys.

* This expansion also takes place in minor-keys, but this time, the 1st degree of the minor scale moves to iv or ii and then to V or V7th returning to the 1st degree of the minor scale.

  LESSON 8 MODULATION   Ø Modulation is the change of key that takes place in a melody that is not permanent. It occurs when accidental adds to the same type of notes, and the phrase ends with the cadence of the new key.   This image shows the key before modulation, it also shows the  pivot chord moving into the modulation of the new key, and it  gives an example of direct modulation. https://i.stack.imgur.com/bpwQT.png   Ø The dominant key is most frequently used to modulate in major-key. In minor keys, this can only happen when the 7th scale degree is not raised by a semitone and also not acting as a dominant.       Ø Some of the other keys used when modulating are those having either a sharp or flat or none, like the relative minor. These are the 4 th , 5 th , and 6 th scale-degree in major-key and also used as pivo chord.  In this melody, using a melodic line with figure base and chord symbols, you would notice the modulation as it begins with a pivot modulation by a common

 ENTRY 9 THE 7th CHORDS Part 1 * The 7th chord is made-up of an additional note above the triad, the  notes arranged with an interval of a third between them. The  distance between each third determines the chord quality.  There are five types of 7th chord qualities that I will explain along with how they are arranged. * Beginning with the ' major minor 7th', this is also the dominant 7th chord, it is identified as Mm7 or by using the 'letter name' of the root note before the number 7, e.g. C7. From the root note, this chord has a major triad and a minor 7th. This chord is diatonic of the 5th degree  in major-scales and also the 5th degree   in minor-scales .   * The 'major, major 7th' chord is identified as Maj7 or by using the 'letter name' of the root note before with M7. This chord has a major triad and a major 7th from the root.  This chord is diatonic of the 1st and 4th degree  in major-scales and the 3rd and 6th degree   in minor-scales . * The &#
