Compose a parallel period, which will make up your A section.

A parallel period is a type of phrase structure, that consists of a 4 bar question and 4 bar answer that mirror each other. Typically the first 2 bars of the question will be repeated for the first 2 bars of the answer. In this particular parallel period, the first 3 bars of the question are repeated in the answer.

Tip: Take your sequence and repeat it again in bars 5-8: simple!
