ENTRY 8


Figured Bass and Lead-Sheet Symbols

* Triads can be arranged in three positions and these are called root position, first inversion and second inversion. These inversions can be identified in figured bass and lead-sheet with the use of various symbols.

* Having a triad in root position, the root note is in the bass, for example, the C major triad, in root position the C would be the bass note with E and G above it. This is made up of a major third and a perfect fifth from the bass note. The symbol used in this inversion for figured bass is 5/3 and the lead-sheet, a capital C.  

* The first inversion would have the third degree of the triad in the bass, for example, using C major E would be in the bass with G and C  above it. This is made up with a minor third and a minor sixth from the bass note. In this inversion, the figured bass used 6 or 6/3 and the lead-sheet used C/E.

* In the second inversion, the fifth degree of the triad is in the bass with the first and third-degree above it. This is made up of a perfect fourth and a major sixth from the bass note. In this inversion, figured bass uses 6/4 while C/G for lead-sheet.

* Lead-sheet music also uses other symbols to identify triads, for example, the C triad in root position the augmented triad can use either C+ or Caug, the C minor triad use C- or Cm and the C diminished triad is C⁰ or Cdim. Also the C triad in the first inversion, C augmented is either C+/E or Caug/E, while the C minor triad is C-/E♭ or Cm/E♭ and the C diminished is C⁰/E♭ or Cdim/E♭. Furthermore, in the second inversion, the C augmented uses C+/G♯ or Caug/G♯, while the C minor is C-/G or Cm/G and the C diminished is C⁰/G♭ or Cdim/G♭. 



These are examples of the lead-sheet symbols using the C major triad. Starting left, the first triad is in root position, followed by the first and second inversion. 


These are examples of the minor triad lead-sheet symbols.


These are the augmented triad lead-sheet symbols.



These are lead-sheet examples of diminished triads.
 
   

 These are the figured bass symbols, starting from left the first symbol is in root position, sometimes nothing is used for this position. Next, the first inversion and it is followed by the second inversion. 


This is an example of how figured bass are arranged throughout a melody.

This is a performance of the triads using the B♭ major scale and the G 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 &#
