Music - Catching, then holding the listener's interest

After doing the readings, I found that the hook is the most important part of catching someone's interest considering that it initially appears at the beginning of a song/musical piece. However, it can sometimes be hard to maintain someone's interest throughout a song/musical piece. In order to do that, one should know what kind of feelings/emotions they are trying to reveal from the listener, whether it is a happy, exciting, sad, or jealous emotion. For instance, when creating a video or any audio projects to celebrate the Martin Luther King Jr. Day, one would play inspirational music. The kind of music that will motivate and empower students (in the college setting) in developing and implementing leadership skills and abilities. The music would be with high beats and high tones of trumpets, saxophones, and drums, for example. The rhythm of the music will be fast pace and reaching higher and higher notes as a symbolism of reaching and accomplishing higher and higher goals in life.
