Can you write small repeated sections within larger in music?

Yes, it is possible to write small repeated sections within larger sections in music. This is often done to create a sense of rhythm or structure in a piece of music. For example, a composer might write a small repeated section of four notes that is played twice before moving on to the next section of the music. This can help to create a sense of anticipation and excitement in the listener, as they wait for the next section of the music to begin.
