For section4, the bridge in this section is not only played in rhythm but also with some pitches developed front he motive. The melody follow the bridge in this sections also developed from the simple melody in section 2. And the effects in this section sounds like a symphony.
The bridge of section 5 is also played by drum, however, I used some sound effects to make it sounds like an electronic music, which sounds more towards to modern style. Then the “reverse order” is demonstrated from this section as the melody in this section is actually developed from the melody in section 4.
Then Section 6 is developed from section 3 and section 7 is developed from section 2. And finally, section 8 is corresponding to section 1 as it used the same instrument with section1 (the introduction) and is in the same style but played the different melody. the melody played here is actually a repeat of a phrase from the previous melody.
