Build a Class Song

Overview

Students work in three or four groups to compose, rehearse and perform a short rhythmic ostinato on xylophones. They learn how separate musical parts can be combined into a coordinated class performance, while making deliberate choices about rhythm, repetition, dynamics and structure.

Learning intentions

• We are learning to create and perform a simple repeating rhythm.
• We are learning to use musical symbols, key words and phrases to plan a rhythm.
• We are learning to listen, keep a steady beat and perform as part of an ensemble.
• We are learning to explain how our group’s part contributes to a class song.

Success criteria

• I can create a one- or two-bar rhythm that repeats steadily.
• I can record my group’s rhythm using simple notation, words or symbols.
• I can teach our part clearly to another group.
• I can perform my part while listening and responding to the other parts.

Curriculum links

• Music — creating and presenting: students explore, generate, practise and present rhythmic ideas.
• Music — communicating and interpreting: students listen, respond and discuss how musical elements work together.
• Music — participating and contributing: students collaborate, take responsibility and contribute to a shared performance.
• English — Writing Processes: Planning: students reduce ideas into key words and phrases when recording their musical plan.

Lesson structure (45 minutes)

1. 0–5 min · Hook and pulse. Teacher welcomes students to the “class band”, establishes a steady four-beat pulse by clapping, and plays a brief teacher-selected performance clip through the opening performance clip. Students identify repeated patterns, instruments and ways performers stay together. Ask: “What makes separate parts sound like one song?” Accept ideas such as steady pulse, repetition, listening, clear starts and controlled volume.

2. 5–10 min · Model a simple ostinato. Teacher uses the rhythm modelling slides to display a four-beat pattern such as “ta ta ti-ti ta”, claps it, then transfers it to two or three comfortable xylophone notes. Model starting together, repeating four times, and stopping on a shared signal. Students echo the rhythm first by speaking or clapping, then finger the beat silently. Explain that an ostinato is a short musical pattern that repeats. Remind students to use soft, controlled mallets and to damp the bars with a hand when stopping.

3. 10–13 min · Form groups and plan. Teacher forms three or four mixed-ability groups of approximately six to eight students. Assign roles: rhythm designer, notation recorder, xylophone players, pulse keeper, conductor and encourager; roles may be shared. Distribute the group rhythm planning grid and clarify that each group must create a simple one- or two-bar pattern, choose up to three notes, and decide a group name and start signal. Students brainstorm, clap and record key words, symbols or note values rather than writing full explanations.

4. 13–25 min · Compose and rehearse. Teacher circulates, checking that each rhythm fits the agreed four-beat pulse and is playable at a steady tempo. Use the prompts on the composition and rehearsal slides: “Can you clap it steadily?”, “Is it simple enough to repeat?”, “Where will you breathe or pause?”, and “How will the conductor signal start and stop?” Students test their idea by clapping, revise it if necessary, then rehearse on xylophones. The pulse keeper quietly taps four even beats while players practise.

5. 25–34 min · Teach the parts. Teacher brings the class together and explains that each group will teach its part in no more than two minutes. Groups take turns demonstrating their rhythm, teaching it by echo or using their worksheet, and naming their start and stop signals. The class practises each part by clapping first, then the selected group plays it on xylophones. Students listening identify one feature that helps them follow each part.

6. 34–41 min · Assemble and perform. Teacher uses the class-song structure slides to show the arrangement: Group 1 begins; Group 2 joins after four repetitions; Group 3 joins after four more; Group 4 joins if used; then the conductor signals a final repetition and stop. Conduct a rehearsal, making adjustments to tempo, balance and dynamics. Students perform the complete class song, listening across the ensemble rather than playing louder than others. If there are three groups, Group 1 may begin and end the piece.

7. 41–45 min · Reflect and exit. Teacher leads a brief discussion: “Which musical choice helped the parts fit together?” and “What did you do when another part joined?” Students complete the Success Criteria Exit Ticket Slips, ticking the criteria they achieved and writing one specific next step. Collect the slips as students return mallets and instruments safely.

Resources

• Classroom xylophones, enough for each group to share safely
• Mallets and a clear storage system
• Whiteboard and markers
• the complete class-song teaching deck
• the group rhythm planning grid
• the Success Criteria Exit Ticket Slips
• Teacher-selected short instrumental performance clip embedded in the slide deck
• Timer or visible clock

Assessment

• During composition, listen for a rhythm that fits four beats, can be repeated and is playable with controlled technique. Ask groups to clap their pattern before using instruments.
• During teaching and performance, observe steady pulse, accurate repetition, listening, appropriate volume, cooperation and response to start and stop signals.
• Use the exit slips to identify whether students can describe a successful musical choice and a next step. Note groups needing further work with pulse, notation or ensemble balance.

Differentiation

• Support students with a prepared bank of simple four-beat patterns, visual beat boxes, colour-coded notes and the option to speak or draw symbols instead of using formal notation.
• Pair less confident players with a pulse keeper or experienced musician. Allow students to practise on desks by tapping before transferring the pattern to xylophones.
• Provide EAL learners with visual modelling and sentence starters: “Our rhythm repeats…”, “We start when…”, and “Our part fits because…”.
• Extend confident groups by adding a planned dynamic change, a contrasting middle section or a different timbre, while keeping the underlying pulse steady. Ask them to justify what they include and leave out of their final arrangement.
