An "overture" is a musical introduction that often precedes a larger work, such as an opera or a symphony. It sets the tone for the performance and introduces key themes or motifs that will be explored later. Overtures can be instrumental or include vocal elements, and they are typically composed to engage the audience's interest right from the start. In a broader context, the term "overture" can also refer to an initial proposal or offer, especially in negotiations or discussions. For example, a diplomatic overture might involve a country reaching out to another to discuss potential cooperation or peace talks. This usage emphasizes the idea of opening a dialogue or creating an opportunity for further engagement.
