Active learning ideas

Harmony and Dissonance

Active learning is crucial for understanding harmony and dissonance because it moves beyond theoretical definitions to direct musical experience. By engaging in composition and improvisation, students develop an intuitive grasp of how these concepts shape musical feeling, making abstract ideas tangible and memorable.

Activity 01

• Experiential Learning
• 60 min · Individual

Composition: Tension and Release

Students compose a short 8-bar melody. They must intentionally use at least two dissonant intervals or chords, followed by a resolution to a consonant sound. They can use digital audio workstations or traditional notation.

Explain how composers use dissonance to evoke specific emotional responses.

Facilitation Tip

During the Experiential Learning activity 'Composition: Tension and Release,' circulate to offer specific feedback on students' interval choices and guide their placement of dissonances for maximum expressive effect.

Activity 02

• 45 min · Small Groups

Listening Lab: Genre Analysis

Students listen to excerpts from different genres (e.g., classical, jazz, film scores). In small groups, they identify instances of harmony and dissonance and discuss the emotional effect each creates. They record their findings in a shared document.

Compare the impact of consonant versus dissonant harmonies in different musical genres.

Facilitation Tip

For Collaborative Problem-Solving in 'Listening Lab: Genre Analysis,' ensure groups are assigning roles to ensure all members contribute to identifying and discussing the harmonic language across genres.

Activity 03

• 30 min · Whole Class

Improvisation: Dissonant Exploration

Using a simple chord progression, students improvise melodies. The teacher or a designated student introduces specific dissonant notes or short phrases, encouraging the class to react and resolve the tension. This can be done on keyboards or with vocal improvisation.

Construct a short musical phrase that effectively uses both harmony and dissonance.

Facilitation Tip

In 'Improvisation: Dissonant Exploration,' use the Experiential Learning methodology by encouraging students to experiment freely with dissonant sounds before guiding them through a reflection on what felt tense and what felt resolved.

A few notes on teaching this unit

Teachers often find success by framing dissonance not as an error, but as a powerful expressive tool. Start with clear examples of consonance and dissonance, then move quickly to guided practice where students experience these sounds firsthand through composition and improvisation, fostering a deeper, more nuanced understanding.

Successful learning looks like students confidently identifying and employing both consonant and dissonant sounds in their own musical creations. Students will be able to articulate the emotional impact of specific harmonic choices and recognize their deliberate use by composers in diverse musical contexts.

Watch Out for These Misconceptions

• During 'Composition: Tension and Release,' students might believe that their chosen dissonant intervals are simply 'wrong' notes rather than deliberate compositional choices.

  Redirect students by asking them to explain the emotional effect they intended with their dissonant intervals and guide them in adjusting the placement or resolution of these sounds to achieve their desired outcome.

• During 'Improvisation: Dissonant Exploration,' students may conflate playing 'wrong' notes with intentionally creating dissonance, viewing their improvisations as mistakes.

  Encourage students to embrace the sounds they are making, asking them to identify which moments felt tense or unresolved and which felt stable, reframing their improvisations as explorations of harmonic color rather than errors.
