MUS 142 Lecture Notes - Lecture 3: Chord Progression, Subdominant, Chromatic Scale
MUS 114: Guided Notes
Week 3: Monday, Jan 25
Topic: Chapter 3: Harmony: Musical Depth
Chapter 4: The Organization of Musical Sounds
Chapter 3: Harmony: Musical Depth
Slide 1: Harmony: Musical Depth
A.Harmony: Simultaneous combination of sounds
B. Chord: Three or more notes sounded together
>chord progression
C. Scales: Collection of pitches arranged in order
>ascend or descend
>major or minor
D. Octave: interval spanning eight notes
>Frequency is doubled/sameness to sound
E. Triad: Three-pitch chord, every other note in a scale
>most common chord in Western Music
Slide 2: The Organization of Harmony
A. Tonic: first note of a scale
>”home base”
>all other pitches of scale are ordered around tonic
>referred to as tonality
B. Primary Chords of a “key” (tonality)
>tonic = I/1st note of scale
>subdominant = IV/4th note of scale
>dominant = V/5th note of scale
Slide 3: Consonance and Dissonance
A. Tension and release as music moves in time
>melodic balance is based on relationship between tension and relaxation
B. Tension = dissonance, conflict
C. Release = consonance, relaxation

Slide 1: the organization of musical sounds: pitches named using letters a-g, western music divides octave into twelve equal semitones (half-steps) Slide 2: the chromatic scale: chromatic scale = 12 half-steps of the octave, two half-steps = one whole step. >visualized on piano keyboard, all white and black keys between two pitches an octave apart.
