7th Chords Part 2

Lesson 10

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 how to create a seventh chord, construct the five common seventh qualities, and show a diatonic seventh chord in the key of A Major.


The video above shows how to create seventh chords, namely major sevenths, minor sevenths, and dominant sevenths.


The video above explains how the five common seventh chords are constructed and what music genres each quality of the seventh chords are frequently used in.

The above image consists of the five common seventh chords ascending and descending in the keys of F major, G major, and A major. 


This is me playing the arpeggiated seventh chords in F, G, and A major.

Diatonic Sequences

Image
   Lesson 23 October 19th, 2021 Lesson 23 Lecture notes: A sequence is made when a musical idea is expressed , then repeated one or more times . Each repetition of the original idea is transposed up or down from the previous iteration by a consistent interval . A basic musical idea usually comes in either  half , full , or t wo measures . This is what ultimately becomes the sequence pattern when expressed in successive repetition . There are two main types of sequences in music which include the ascending sequences and the descending sequences . The ascending sequences include the ascending-fifth sequence and the parallel 6/3 chords sequence . The descending sequences include the descending-fifth sequence , the Pachelbel sequence , and the descending parallel 6/3 chords sequence . The various sequences follow a specific chord progression pattern . For example, the descending-fifth sequence progression would be I - IV - viio - iii - vi - ii - V - I . The Pachelbel

Dominant Sevenths

  Lesson 17 March 22nd, 2021 Lesson 17 Lecture notes: The dominant seventh chord contains two tendency notes , including the leading tone and the chordal seventh . In a dominant seventh chord , the third degree of that chord is the leading tone for the tonic chord, which would resolve up to the tonic note ( 7 - 1 ). In a dominant seventh chord , the seventh degree , also known as the chordal seventh , is the tonic chord's fourth degree. This note would resolve down to the third degree of the tonic chord ( 4 - 3 ). The two predominant chords that lead to the dominant chord are the minor second and the perfect fourth . The basic phrase model would look like ( T - PD - D - T ) whenever used. Parallel fifths are easy to occur. An excellent way to avoid this is by omitting a note in either the dominant seventh chord or the tonic chord. The note that can be left out of either chord is the fifth-degree note .  Root position ( 7 ) and second inversion ( 4/3 ) dominant seve

Variations

Image
  Lesson 30 February 4th, 2022 Lesson 30 Lecture notes: There are multiple types of variations , inclusive of the continuous variation , sectional variation , figural variation , chromatic variation , textural variation , and timbral variation . The continuous variation is the continuous flow of a musical idea and a Fortspinnung phrase structure. This variation type was widely used in the Baroque era of music. Fortspinnung is the development process of a specific musical motif . First, the motif in question is developed into a complete musical using sequences , intervallic changes , and simple repetitions . There are two different types of continuous variations . Ground bass or passacaglia and chaconne . The ground bass / passacaglia  is when there is a repeating bass line , and only the upper voices change or vary . In the chaconne , the harmonic progression is repeated and varied while the bass remains the same for several successive variations , but it e
