What role does texture play in classical compositions and how does it contribute to the overall musical structure and expression?

Texture in classical compositions refers to how different musical lines and voices interact with each other. It can be thick or thin, and can change throughout a piece. Texture contributes to the overall musical structure by creating layers of sound and highlighting different melodies or harmonies. It also adds depth and richness to the music, enhancing the emotional expression and creating a sense of balance and cohesion in the composition.
