Building Harmonic Layers

Overview

Lesson 11 of 30 in Creating Music with Technology. Students develop an existing melody by testing chord progressions and backing-vocal ideas, then make creative decisions based on style, sound and musical effect.

Learning intentions

• WALT experiment with chords that support a melody.
• WALT create and record a simple backing-vocal part.
• WALT use music technology to arrange and refine musical ideas.
• WALT explain how harmony changes the mood and impact of a melody.

Success criteria

• I can choose or create chords that fit my melody.
• I can perform or programme a suitable backing-vocal part.
• I can record, balance and edit harmonic layers in a digital audio project.
• I can describe one musical choice and explain its effect.

Curriculum links

• Creating and developing musical ideas using sound, technology and musical elements.
• Performing and recording music with control, expression and awareness of ensemble parts.
• Understanding how harmony, texture and timbre communicate mood and meaning.
• Developing the refreshed NZ Curriculum capabilities of creative thinking, collaboration, communication and managing self.

Lesson structure (50 minutes)

1. 0–5 minutes – Hook and listening comparison Open with the hook and listening slides. Play or demonstrate the class melody first on its own, then with a simple chord pattern and backing vocal. Ask: “Which version feels more complete, and what caused the change?” Students briefly identify mood, texture and vocal placement.

2. 5–12 minutes – Teach harmony choices Use the harmony teaching slides to review melody, chord and bass relationships. Demonstrate two or three suitable chord options using the class melody, such as major, minor or a repeated four-chord pattern. Explain that students do not need advanced theory: they should listen for whether a chord sounds settled, tense or unsuitable. Model a backing vocal using held notes, repeated syllables or a short response phrase.

3. 12–17 minutes – Plan in pairs Place students in five pairs and distribute the harmony planning worksheet. Each pair writes the melody’s key or tonal centre if known, proposes two or three chords, and sketches a backing-vocal idea. Encourage students to sing, play or programme options before committing. The teacher checks plans and supports pairs who are unsure about chord choices.

4. 17–32 minutes – Create and record Use the creation task slides for the step-by-step workflow. Pairs open their existing digital projects, duplicate the melody track, and add either programmed chords, a keyboard/guitar part or a suitable loop. They then record or programme one backing-vocal layer. Students should keep the original melody clear, name their tracks and save a new version. The teacher circulates, helping with input levels, timing, key matching and safe equipment use.

5. 32–40 minutes – Refine the arrangement Pairs listen back with the melody, harmony and backing vocal together. They make at least two changes, such as altering a chord, moving the backing vocal to a different section, changing its rhythm, adjusting volume or adding a short fade. Ask pairs to mute and unmute tracks so they can judge what each layer contributes. Students complete the reflection questions on the harmony planning worksheet.

6. 40–47 minutes – Share and peer feedback Each pair plays approximately 30–45 seconds of its arrangement to another pair or to the class, depending on equipment and confidence. Use the peer-feedback slides to structure feedback: one effective harmony choice, one clear backing-vocal feature and one possible refinement. Feedback must refer to musical evidence, such as mood, balance, texture or contrast.

7. 47–50 minutes – Exit reflection Finish with the success-criteria exit ticket slips. Students identify which success criteria they met and write one specific next step for lesson 12. Collect the slips as they leave and ensure all digital work is saved in the agreed class folder.

Resources

• Computers or tablets, one per pair
• Digital audio workstation or music-making software
• Headphones and appropriate audio interfaces
• MIDI keyboards, microphones or classroom instruments
• Existing melody projects from earlier lessons
• the complete lesson slide deck
• the harmony planning worksheet
• the success-criteria exit ticket slips
• Whiteboard and markers
• Shared class folder or cloud storage

Assessment

• Observe whether students test and justify chord choices, rather than selecting sounds randomly.
• Check each project for a clear melody, an audible harmonic layer, a backing-vocal idea, named tracks and at least two refinements.
• Use peer feedback, worksheet responses and exit tickets to assess understanding of harmony, texture and creative decision-making.

Differentiation

• Support: provide a limited selection of pre-tested chord loops in the project, allow students to hum or play backing vocals before recording, and pair a confident technology user with a student who needs support.
• Support: offer a visual workflow on the slides and teacher modelling in small steps; provide sentence starters such as “The harmony changes the mood by…” and “Our backing vocal supports the melody because…”.
• Extension: challenge students to use contrasting harmony in a second section, add a countermelody, or compare a diatonic chord choice with a deliberately surprising chord.
• EAL/SEN: accept spoken, sung or diagrammatic planning; use headphones, reduced screen clutter and short teacher check-ins. Allow an instrumental or programmed backing part if recording vocals creates anxiety or sensory discomfort.
