The song mainly makes use of the lyrics, keyboard and chords. There is a consistent beat played throughout the song so its time signature is a simple 4/4. This drum beat has been adopted from song by Joe Tex. The rhythm of this song is consistent; hence the tempo stays the same. The structure of this song can be broken down in to verse, chorus and bridge. Like other modern hip hop songs, this song also has a simple order in its structure. The song starts with a chorus sung by both B.O.B and Bruno Mars. Forty five seconds into the song, B.O.B sings the verse followed by a bridge sung by Bruno Mars and then chorus again. This ordered structure repeats twice. Near the end, the order changes from chorus, bridge, chorus. Most of the modern music has almost all of the above mentioned features and these features suggest that they are quite predictable. Classical music on the other hand is very diverse and swerving.

The symphony is purely instrumental and its complete musical piece is about thirty minutes long. This piece is melody driven which is difficult to find in the modern pop music. Unlike “Nothin’ on you” by B.O.B, this symphony has no structural limitations. Therefore, the breakdown of its structure is not as simple. Symphony number 40 changes its tempo as it has varying rhythms. These varying rhythms are very complex yet the whole piece is temporally very sophisticated.
Mozart’s symphony number 40 makes use of many instruments such as the flute, oboes, clarinets, horns, bassoons and strings.

The structure of this symphony can be broken down in to four segments of tempo markings namely molto-allegro, Andante, Menuetto and
