What are the different modes used in music and how do they influence the overall composition and style of a piece?

Modes in music are different scales that create a specific sound or mood. They influence the overall composition and style of a piece by determining the notes that are used and the relationships between them. Each mode has its own unique characteristics that can evoke different emotions or create a particular atmosphere in the music. By choosing a specific mode, composers can shape the overall feel and direction of a piece, giving it a distinct identity and flavor.
