  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

  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.   https://inalbis.net/wp-content/uploads/2014/11/Part-Writing-Secondary-Leading-Tone-Chords.png      Ø In recognizing a secondary leading tone chord to the dominant, it is a converted 4 th -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 5 th . In addition, an added minor third above the 5th makes it a fully diminished 7th
