The opening section of a musical composition or a performance

"Introduction" in music refers to the opening section of a composition that precedes the main body of the piece. It serves several important functions, setting the tone, establishing the musical atmosphere, and preparing the listener for what's to come. The introduction often provides context and anticipation for the main themes and ideas that will follow.

In terms of structure and content, an introduction can take various forms. It might feature a brief musical passage that contains motifs or themes that will later be developed in the main body of the composition. Alternatively, an introduction can create a distinct mood or evoke a specific emotion, providing a musical backdrop that engages the listener's attention and curiosity.

Composers use introductions strategically to captivate the audience and introduce them to the musical world they are about to enter. Depending on the genre and style of the composition, the introduction might be dramatic, mysterious, tranquil, or any other mood that serves the purpose of the piece.

In addition to preparing the listener, introductions also provide performers with a starting point and a context for their interpretation. They often include musical elements that grab the listener's attention and set the stage for the main thematic material.

The length and complexity of an introduction vary greatly depending on the piece's overall structure and intent. In some cases, the introduction can be quite short, serving as a mere transition into the main part of the composition. In other cases, particularly in larger works, the introduction can be an extended and significant musical section that establishes the groundwork for the composition's subsequent development.
