Lesson 10 November 16th, 2020 Lesson 10 Lecture notes: Seventh chords are simply triads with an extra third stacked on top. The  MM7 would have a major triad + major third , creating the major 7th chord. The Mm7  would have a major triad + minor third ,  creating the dominant 7th chord. The mm7 would have a minor triad + minor third , creating the minor 7th chord. The ø7 would have a diminished triad + major third , creating the  half - diminished 7th chord. The o7 would have a diminished triad + minor third , creating the fully diminished 7th chord. Seventh chords that are uncommon are augmented triads with a major or minor seventh and a minor triad with a major seventh . In the Classical period , seventh chords were only built on chords 2 , 5 , and 7 . Jazz standards frequently end with unresolved seventh chords . The photo above shows all of the lead sheet symbols, including triads, sevenths, ninths, elevenths, and thirteenths. The photo above explains

  Lesson 9 November 9th, 2020 Lesson 9 Lecture notes: Seventh chords consist of four notes , including  a root , third , fifth , and seventh , all stacked together. There are five common qualities of seventh chords : the  Major   7th , minor   7th, Dominant   7th , Half diminished   7th and diminished   7th .   The abbreviations for seventh chords are Major 7th ( MM7 ), minor 7th ( mm7 ), Dominant 7th ( Mm7 ), Half diminished 7th ( ø7 ), and diminished 7th ( o7 ) The seventh chord in a Major diatonic key is half - diminished ,  but the seventh chord is  fully diminished   in  minor diatonic keys . The figured bass symbols for seventh chords are  root position ( 7 ), first inversion ( 6/5 ), second inversion ( 4/3 ), and third inversion ( 4/2 or 2 ). The photo above shows the five common qualities of seventh chords in the key of C Major. The photo above shows the seventh chord's numerous qualities and how to construct them with the given formula, symbols, and notes

Lesson 8 November 2nd, 2020 Lesson 8 Lecture notes: Inversions/Figured bass is indicated by three symbols inclusive of 5/3 ,   6/3 ,   or 6 and 6/4 . Inversions/Figured bass in a triad can be in either root position , first inversion , or second inversion . Root position is when the root note is in the bass. This is displayed with the symbol 5/3 . First inversion is when the third note is in the bass. This is displayed with the symbol 6/3 or 6 . Second inversion is when the fifth note is in the bass. This is displayed with the symbol 6/4 . The numbers in the figured bass symbols indicate which intervals are above the bass note . For example,  5/3  means that the intervals over the bass note are a fifth and a third . The above photo shows triad inversions in Root Position, First Inversion, and Second Inversion in C Major's key.  The above photo shows triad inversions in Root Position, First Inversion, and Second Inversion in all four quality sounds. The qualities di
