THE 7th CHORD

IDENTIFYING FIGURED BASS NOTATION
&
LEAD SHEET SYMBOLS
FOR 7th CHORDS 


* Other than using notes in the staff there are other ways to identify 7th chords and their inversions. This can be done by using the figured bass notation and the lead sheet symbols. Figured bass notations are placed just below the bass clef staff while lead sheet symbols are above the treble clef staff. 

* Figured bass uses roman numerals followed by numbers as notations to identify the 7th chord. I am going to explain how they are arranged along with the quality and type of  7th chords they represent in the diatonic. 

* A major, major first degree 7th chord of a major-scale in root position is identified by I 7/5/3, I 7/5 or 7 in the first inversion, it is I 6/5/3 or I 6/5, second inversion, I 6/4/3 or I 4/3 and third inversion it is I 6/4/2 on I 4/2


* A major, minor 5th-degree 7th chord of a major-scale in root position is identified by V7/5/3, V7/5 or V7 in the first inversion, it is V6/5/3 or V6/5, second inversion, V6/4/3 or V4/3 and the third inversion it is V6/4/2 or V4/2.


* A minor, minor 2nd-degree 7th chord of a major-scale in root position, is identified by ii7/5/3, ii7/5 or ii7 in the first inversion, it is ii6/5/3 or ii6/5, second inversion, ii6/4/3 or ii4/3 and the third inversion it is ii6/4/2 or ii4/2.


* A half-diminished 7th-degree 7th chords of a major-scale in root position is identified by 𝆩iiv7/5/3, 𝆩iiv7/5 or 𝆩iiv7 in the first inversion, it is 𝆩iiv6/5/3 or 𝆩iiv6/5, second inversion, 𝆩iiv6/4/3 or 𝆩iiv4/3 and the third inversion it is 𝆩iiv6/4/2 or 𝆩iiv4/2.


* A diminished 7th-degree 7th chords of a minor-scale in root position is identified by 𝇈iiv7/5/3, 𝇈iiv7/5 or 𝇈iiv7 in the first inversion, it is 𝇈iiv6/5/3 or 𝇈iiv6/5, second inversion, 𝇈iiv6/4/3 or 𝇈iiv4/3 and the third inversion it is 𝇈iiv6/4/2 or 𝇈iiv4/2.


* Lead sheet symbols use letter along with the number 7 to identify the 7th chord. Determining whether if these chords are major, minor, diminished or half-diminished, it will use characters like (M,m,𝇈,𝆩) before the number 7. I am going to give some examples of how they are arranged.

* A major, major 7th chord using C major 7th in root position is identified by CM7, in the first inversion, it is CM7/E, second inversion, CM7/G and third inversion it is CM7/B.  


* A major, minor 7th chord using G major, minor 7th in root position is identified by G7, in the first inversion, it is G7/B, second inversion, G7/D and third inversion it is G7/F.


* A minor, minor 7th chord using D minor 7th in root position is identified by Dm7, in the first inversion, it is Dm7/F, second inversion, Dm7/A and third inversion it is Dm7/C.


* A half-diminished 7th chord using B half-diminished 7th in root position is identified by B𝆩7, in the first inversion, it is B𝆩7/D, second inversion, B𝆩7/F and third inversion it is B𝆩7/C.



* A diminished 7th chord using G diminished 7th in root position is identified by G𝇈7, in the first inversion, it is G𝇈7/B♭, second inversion, G𝇈7/D♭ and third inversion it is G𝇈7/F♭.

  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 &#
