Rhythm Chord Basics

Overview

In this lesson (lesson 5 of 30) you will learn the essential music theory tools for songwriting: scales, chords, and rhythm. You will use what you know to build a short, tech-ready musical idea you can continue in later lessons.

Learning intentions

• WALT identify and use major and minor scale patterns to write melodies.
• WALT understand how chords are built from scale degrees (triads) and how they support a songwriting idea.
• WALT create rhythm patterns that fit a steady pulse for songwriting with technology.
• WALT describe musical choices using clear, music-theory language.

Success criteria

• I can name a major or minor scale and apply its pattern to a short melody.
• I can build a triad chord from scale degrees and explain how it matches the scale.
• I can create and notate a rhythm pattern that fits the beat/pulse and is repeatable.
• I can give at least one reason for my choices using scale/chord/rhythm terms.

Curriculum links

• Creating music using technology to develop musical ideas and refine them (NCEA-aligned focus).
• Using musical elements (pitch, rhythm, harmony/structure) with increasing accuracy.
• Communicating musical understanding through discussion and short written/oral explanations.
• Developing and applying skills to respond to feedback during making.

Lesson structure (50 minutes)

1. 5 minutes – Hook + purpose Start the introduction slides with the question: “What makes a song sound ‘right’—the notes, the chords, or the rhythm?” Students quickly vote with fingers, then share one idea. Tell them today they will learn the theory behind all three.

2. 10 minutes – Scales mini-teach Use the introduction slides to introduce major vs minor feel, then show the step pattern concept (tone/tone/semitone). Model building a simple 5-note scale phrase on keyboard/MIDI (or clap/ta). Students write the scale degrees (numbers) on the worksheet as a reference.

3. 8 minutes – Chords mini-teach (triads) On the introduction slides, explain that many pop/rock/film-style songs use triads formed from scale degrees (1-3-5). Play two chords from the same scale (one major, one minor triad) and students label them as “sounds tense/relaxed” using minor/major language.

4. 10 minutes – Rhythm focus (steady pulse + pattern) Still using the introduction slides, teach rhythm as “pattern over a pulse.” Demonstrate 2-beat and 4-beat patterns (using on-beat/off-beat) and connect it to songwriting: repeat a rhythm so the melody/chords can sit on top. Students mark a simple 4-beat rhythm on the worksheet (teacher provides a template on the deck).

5. 12 minutes – Create: chord + rhythm + short melody Students work in pairs at technology stations (or teacher-led computer). Using the scale choice from the worksheet, they:

• select one triad chord in the chosen scale,
• program or tap a repeatable rhythm pattern,
• add a 3–5 note melody fragment that uses only notes from the scale. Teacher circulates with a checklist: scale notes only, triad matches scale degrees, rhythm is consistent with the pulse. Use the introduction slides “Try/Check” prompts to keep the task clear.

6. 5 minutes – Plenary: theory talk + feedback Return to the introduction slides for a quick share. Each pair states: their scale (major/minor), their triad degrees (1-3-5), and one rhythm detail (“on-beat start” or “off-beat emphasis”). Do a “glow and grow”: one thing that sounds strong, one improvement to make next lesson.

Resources

• the introduction slides (single deck covering hook, mini-teach, instructions, and plenary prompts)
• the worksheet (one page: scale degrees, triad building, rhythm marking, short reflection)
• Classroom audio output (speaker/headphones as available)
• Keyboard/MIDI or basic music software with chord/scale support
• Metronome or beat track (teacher laptop/tablet app is fine)
• Whiteboard or digital board for teacher modelling (scales and rhythm templates)
• Student pens/pencils and the completed worksheet
• Optional: small rhythm cards (beat/off-beat) if technology access is limited

Assessment

• Formative during making: teacher checks scale-only melodies, triad degree accuracy, and pulse-consistent rhythm patterns.
• Worksheet evidence: correct scale degrees, triad labels, and a clearly marked rhythm pattern.
• Plenary communication: each pair uses music-theory language to explain choices and respond to one feedback point.

Differentiation

• Support: provide a “note bank” on the worksheet (e.g., C major/A minor options only) and allow tapping rhythm before programming.
• Support: sentence starters on the deck for theory talk (“My chord uses scale degrees…”, “My rhythm starts on the…”).
• Extension: challenge students to create two different triads from the same scale and hear how the mood changes, then choose the one that best supports their rhythm.
• EAL/SEN: allow oral responses for the plenary (recorded on teacher device if needed) and keep written tasks short with clear examples.
