Final answer:
The question addresses how a bassline changes throughout a song, which is often used to support the narrative or emotional shifts in the music. For example, changes in rhythm, volume, or pitch in the bass can enhance the storytelling and dynamics of a song.
Step-by-step explanation:
The question 'How does the bassline later morph during the song?' pertains to the elements of music and specifically how a bassline evolves throughout a musical piece. In many songs, especially within the rock and roll genre, the bassline provides a foundation for the melody and can transform to create different feelings or to emphasise a shift in narrative or emotional tone. As a song progresses, the bass may change in rhythm, volume, or pitch to complement the dynamics of the lyrics and other instruments, thereby enhancing the overall storytelling aspect of the music. For example, a bassline might start with a steady, calm pattern but then become more complex and intense to reflect a change in the storyline or to build up to a climax.
