Answer:
d) Repetition.
Step-by-step explanation:
Repetition is an element used to create musical form that restates the idea over and over in a piece of music. It involves the repetition of specific musical patterns, motifs, or sections throughout a composition.
Repetition plays a fundamental role in creating structure and coherence in music. By repeating musical ideas, composers can establish familiarity and reinforce the main themes or melodies of a piece. This helps to unify the composition and give it a sense of continuity.
For example, in a classical symphony, the main theme introduced in the opening movement is often repeated later in the composition, either in its original form or with variations. This repetition allows the listener to recognize and connect with the recurring musical idea, creating a sense of anticipation and fulfillment.
Repetition can take various forms in music, including the repetition of a melodic phrase, a rhythmic pattern, a chord progression, or an entire musical section. It can occur within a single instrument or voice, as well as across multiple voices or instruments.
In summary, repetition is an essential element used in music to create form by restating musical ideas over and over throughout a composition. It helps to establish structure, coherence, and familiarity, providing a sense of unity and continuity in the music.
