One piece of music that has multiple changes in dynamics, tempo and articulation is "Bohemian Rhapsody" by Queen. It starts with an acapella intro and followed by a ballad about narrating to his mom that he have killed someone. The third part is an operatic part depicting the narrator's descent to hell. The final part is hard rock music
It all started with a preacher named Archie Fair, a distant relative, make known to him to the guitar and gave him an important role in the dramatic services of the local Sanctified Church. At first he was inclined by the music of his cousin Bukka White, as well as Leadbelly, Blind Lemon Jefferson and Sonny Boy Williamson. But he was also an admirer of jazz players like Charlie Christian, particularly when he was playing with the Benny Goodman Orchestra, and Django Reinhardt. He said that a little bit of all of those people I liked, with my own ideas, shaped the BB King twinging guitar sound.
