Use inquiry in music to extend understanding of the composition principles of repetition and variety:

• Pose questions to guide inquiry into how elements of music can be manipulated to create repetition and variety (e.g., How can we demonstrate repetition and variety using rhythm? How can we manipulate texture to create repetition and variety? How are we using repetition and variety in our techno or hip hop beats and lyrics?)
• Experiment with voice and instruments to explore the inquiry questions.
• Collaborate with peers to document the inquiry process (e.g., traditional and/or invented notation, audio or video recording).
• Rehearse and perform to share inquiry results with others.

Demonstrate how musicians and composers use principles of composition such as repetition and variety as tools to organize the elements of music (i.e., rhythm, melody/pitch, dynamics, timbre/tone colour, texture).

Identify repetition and variety in own music and the music of others, and analyze how it is achieved.

Investigate how phrases in vocal and instrumental music can be repeated or contrasted with other phrases to create larger structural units (e.g., call/response, question/answer, rounds).

Play rhythmic ostinatos inspired by music of various cultures, identifying how repetition and variety are achieved.

Investigate ways that variety can add interest and repetition can hold a musical piece together.

Create and manipulate melodic phrases using repetition and variety.

Demonstrate balance between repetition and variety in a melody.

Demonstrate and discuss how increase in texture (e.g., the addition of melodic/rhythmic patterns or ostinatos) can make music more interesting.

Examine ways that silence can be used in compositions.

Use the Internet and other sources (e.g., guest musicians) to identify, analyze, and create repetition and variety in different styles of music.
