Lesson: Melody, Harmony, Rhythm & Chord Progressions
(Part of Module 3: Music Composition & Song Structure)
Learning Objectives
By the end of this lesson, students will:
- Understand the roles of melody, harmony, and rhythm in music production
- Identify and construct basic chord progressions
- Use rhythm and harmony to support a melody
- Compose musical ideas using a DAW or instrument
Lesson Outline
1. Melody – The Voice of the Song
Definition: A melody is a sequence of musical notes that are perceived as a single cohesive idea. It’s what you sing or hum.
Characteristics:
- Linear and memorable
- Built from scales (major, minor, modal)
- Often uses repetition with variation
- Can be vocal or instrumental
Tips for Writing Melodies:
- Start with a short 3–5 note phrase
- Use stepwise motion with occasional leaps
- Try to end phrases on strong chord tones (like root or fifth)
- Think in “call and response” phrasing
2. Harmony – The Emotion Beneath the Melody
Definition: Harmony is created when two or more notes sound at the same time. It adds emotional depth and color.
Built From Chords:
- Chords = 3 or more notes played together
- Common triads: Major, Minor, Diminished, Augmented
- Seventh chords and extensions add complexity
How Harmony Works:
- Harmony supports the melody by giving it a context
- Chord choices determine the song’s mood (happy, sad, tense, dreamy)
3. Rhythm – The Movement of Music
Definition: Rhythm is the pattern of sounds and silences in time. It’s what makes you tap your foot.
Key Concepts:
- Tempo (measured in BPM): the speed of the music
- Time Signature (like 4/4, 3/4, 6/8): determines beat grouping
- Groove: how rhythm “feels” — straight, swung, syncopated
- Subdivision: whole, half, quarter, eighth notes, etc.
Practical Use:
- Use a metronome to practice timing
- Try drum patterns to explore groove
- Align melodies and chord changes to strong beats
4. Chord Progressions – The Foundation of Harmony
Definition: A chord progression is a sequence of chords played in a specific order.
Popular Progressions:
- I – IV – V – I (e.g., C–F–G–C): Simple and uplifting
- vi – IV – I – V (e.g., Am–F–C–G): Used in many pop songs
- ii – V – I (e.g., Dm–G–C): Jazz and soul standard
- I – V – vi – IV (e.g., C–G–Am–F): Very popular in modern pop
Tips:
- Use chord tones for melodies
- Change chords every 1 or 2 bars
- Experiment with inversions and extensions (7ths, 9ths)
Listening Activity
Pick 2 songs and identify:
- The main melody (hum or sing it)
- The supporting chords (use your ear or app tools)
- The time signature and tempo
- Any rhythmic pattern or groove
Practice Exercise
Task:
- Choose a key (e.g., C major)
- Create a 4-chord progression (e.g., C – G – Am – F)
- Add a simple melody over it (try 4–8 notes)
- Add a basic drum loop or metronome to define rhythm
- Record or program your progression in your DAW
Key Takeaways
- Melody carries the tune, harmony sets the mood, and rhythm drives the song
- Chord progressions are essential for creating emotional flow
- Mastering these three elements helps create songs that are musically rich and emotionally resonant
- Simplicity, repetition, and variation are the keys to songwriting success
