There are certain feelings that are evoked through the themes and metaphors of Marquez, and a style that seems to reflect the magical realism of his novel. Much like a big river of South America, Marquez' style meanders and takes its time; long, twisted and languid, like the story itself. You can see this through the disjunctive portrayal of time, which is a large theme in the book.
From the very name of the book, to the jumping around of viewpoints and stories of characters, we can see the scope of the whole novel. Solitude is a recurring concern of the book. From the location of Macondo, separate from civilization, to the spell of amnesia the village experiences after the arrival of the orphan Rebecca, there is a sense of seclusion. Although the worst fear of the villagers is forgetting there past, while at the same time they are at terms with their isolation. Despite the efforts of JOse Arcadio Buendia to find civilization, we see complacency, or an happier affect with their situation even, when the magistrate tries to impose a kind of rule over the people, who follow Jose Arcadio Buendia's lead in refusing to submit absolute power. However, the book is also about a journey, or multiple journeys: Buendia, in search of enlightenment, a family wanting security, and a people trying to free themselves from the shackles of ignorance and superstition.
Time is another theme in the book. To me it was difficult to place the time, and that's intentional. The chronology shares a similar aspect as the style, being that the book starts off recounting the past. And from there the book continues to jump around. Initially, you feel in touch with the setting in an older time, like the 16th century (considering Ursula's great grandmother' tale), but very quickly continues with seemingly modern inventions. Again, part of progressing the story time and the characters knowledge.
All of this is mixed up because of the reality Marquez invents. He ties it all together by creating a dramatic tension by freely mixing straightforward narrative with the fantastical. He challenges what is real and what is fiction. This subjectivity of reality works nicely with the lucid narrative and journey that Marquez takes us on.
