Unit Plan 12 (Grade 8 Orchestra): Motive & Melody Composition
Compose a 12–16 measure melody using motives, variation, contour, and tonic resolution as Grade 8 orchestra students build expressive, playable themes.
Focus: Compose a longer melody (12–16 measures) that shows clear contour, thoughtful motive repetition/variation, and a strong resolution to tonic within a given key and meter.
Grade Level: 8
Subject Area: Orchestra (Creating • Composing • Performing/Responding)
Total Unit Duration: 5 sessions (one week), 50–60 minutes per session
I. Introduction
In this unit, Grade 8 orchestra students shift from improvising in the moment to composing notated melodies they can perform and share. Starting from a simple motive (short musical idea), they learn how to repeat, vary, and sequence it to build a 12–16 measure melody with a clear shape and ending on tonic. Students think about phrase structure (questions/answers), contour (rising/falling line), and cadence as they draft, revise, and notate their ideas. By the end, they will have a polished, playable melody that could be used as an opening theme, solo line, or future arrangement.
Essential Questions
- What makes a melody memorable and satisfying to listen to?
- How can a simple motive be repeated and varied to build a longer melodic line?
- How do contour, phrasing, and resolution to tonic help a melody feel complete?
- How can key, meter, and rhythm choices support the expressive character of a melody?
- In what ways does composing our own melodies help us better understand the music we perform in orchestra?
II. Objectives and Standards
Learning Objectives — Students will be able to:
- Create short motives (2–4 beats/measures) within a given key and meter using familiar scales and finger patterns.
- Use repetition and variation (change of rhythm, contour, sequence, or range) to develop a motive into a longer 12–16 measure melody.
- Design a melody with intentional contour (clear rise and fall) and phrase structure (question/answer or 4+4 grouping).
- Ensure a strong resolution by ending the melody clearly on the tonic and supporting closing phrases with stable rhythmic and pitch choices.
- Notate the melody correctly on the staff with key signature, meter, pitches, and rhythms that are playable on their instrument.
- Share their melody through performance or peer reading and explain at least one compositional choice related to motive, contour, or resolution.
Standards Alignment — Grade 8 Orchestra (custom, NAfME-style)
- OR:Cr1.8b — Create short string melodies or motives within a given key and meter, showing intentional contour, repetition/variation, and strong resolution.
- Example: Students compose a 12–16 measure melody that varies a motive and resolves clearly to tonic.
Success Criteria — Student Language
- I can write a motive in a given key and meter that fits my instrument.
- I can use repetition and variation to turn my motive into a longer melody.
- I can shape my melody so it has a clear contour and phrases that feel like musical sentences.
- I can end my melody on tonic (home note) in a way that sounds finished and satisfying.
- I can explain at least one compositional choice I made about motive, contour, or resolution.
