LESSON 7

SECONDARY LEADING TONE CHORDS


    Ø This lesson features the secondary lending tone chords acting as the dominant with the leading tone, leading to a tonicized secondary dominant. The ones often used are the fully diminished and the half-diminished inverted 6/5 and 4/3 chords. However, the non-inverted half-diminished and the first inversion of the diminished triad are those not often used.


This image shows the different inversions of the secondary leading tone chord and how it's resolved to the dominant.



    Ø In recognizing a secondary leading tone chord to the dominant, it is a converted 4th-degree chord of the diatonic positioned just before the dominant. With its root taken up a semitone higher, this causes it to become a leading tone and a diminished triad, leading to the 5th. In addition, an added minor third above the 5th makes it a fully diminished 7th chord, while a major third above the 5th makes it a half-diminished chord.

  Ø   Due to the function of the secondary leading tone chord to the 5th, this chord must resolve like a leading-tone chord. When resolving this chord, the root resolves up to the 5th degree of the diatonic. While the 7th of the chord resolves down to the second degree of the diatonic.

 Ø   One of the main reasons for using this chord as a secondary leading tone chord, the triad of this chord is identical to the dominant without the root.


Ø  The secondary leading tone chord can be resolved by any of the scale degrees notes. Except for the diminished or half-diminished chord notes, like the 7th in major and minor keys and the 2nd degree in minor keys, this chord can only be resolved by major and minor chords.

  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 &#
