Below are lesson plans for four activities that are designed to allow students to explore the concepts of consonance and dissonance in music. Activity 1 and Activity 2 introduce the concepts and allow the students to practice listening for and naming consonance and dissonance. Activity 3 allows students who are proficient on a musical instrument to use this knowledge to improvise harmonies which are deliberately consonant or dissonant. Activity 4 helps the students draw comparisons to similar concepts in other disciplines.
Consonance and dissonance are musical terms that have specific, slightly technical meanings, but the basic idea is one that can be grasped even by young children: Musical notes that sound good together are called consonant; notes that seem to clash, or sound unpleasant together, are called dissonant. (If you would like to find out more, please see Consonance and Dissonance.)
Notes that are not in tune with each other are dissonant, of course, but even two notes that are tuned correctly may not sound good when they are played at the same time. Consonance depends partly on the physics of sound (see Harmonic Series and Tuning Systems for more information). But it also depends partly on the musical traditions of a particular culture (the technical meanings of the words come from the Western music tradition), and partly just on personal tastes.
