How does Fitzgerald create dramatic tension leading up to Gatsby's first appearance in 'The Great Gatsby'?

Fitzgerald uses structure to successfully create dramatic tension leading up to Gatsby's first appearance, creating intense mystery around our central character. The first two chapters are utilised for this, as Fitzgerald holds off introducing the character to the reader until we have had lots about him from multiple sources - such as Myrtle Wilson in Chapter Two. This information from secondary sources makes us question who Gatsby is, making the reader eager to find out more. There is also an important appearance at the end of the first chapter, as Fitzgerald presents Gatsby standing on his lawn with his arm reaching out towards the green light. This image will define the character's arc for the rest of the book, as Gatsby's desire for Daisy drives his actions and is ultimately his downfall. Before we have even been introduced to the character Fitzgerald has given us a glimpse into his fate, thus creating further dramatic tension.
