MT1 - {Tonal Harmony} Ch. 3: Intro to Triads and Seventh Chords

Music, chords, or other musical elements built from stacked intervals of a third (both major and minor)

Tertian

A three-note chord consisting of a 5th divided into two superimposed 3rds

Triad

Root position, first inverse and second inversion

Bass positions

Chord with the root notated as te lowest tone 

Root position

A chord with the 3rd as the lowest tone

First inversion

The 5th as the lowest tone

Second inversion 

The distance between two pitches

Intervals

Measures the distance vertically on the staff line

• Number of note names encompassed (ABCDEFG)

Numerical value (size)

ALWAYS start by identifying the numerical value

What should you do when identifying intervals first?

1, 4, 5, 8

Group 1:

2, 3, 6, 7

Group 2:

A Perfect, but CANNOT be major or minor

• Up from tonic in a major scale will always be Perfect (Perfect is the tonic up to the dominant)

Group 1 can be…

A major or minor, cannot be Perfect 

• Up from tonic in a major scale will always be major 

Group 2 can be…

1, 4, 5, 8 - a half step smaller than major without changing the numerical value 

Diminished: Group 1:

1, 4, 5, 8 - a half step larger than major while preserving the numerical value

Augmented: Group 1:

It is to restore a leading tone

What is the purpose of the harmonic minor?

The and the ascending portion, we raise them BOTH and the descending portion looks the same as the natural minor

In melodic minor…?

Doubled
