What is the author's style in The Grass Harp by Truman Capote?

The novella is written in seven chapters and is the retelling of Collin's life spent with the Talbo sisters. The book opens with Collin recalling the grass harp and the happy days spent with Dolly learning lessons about nature and love. Capote uses flashbacks throughout the book to indicate that Collin is remembering parts of his life such as his parents' deaths and his entry into the Talbo world. The flashbacks are a primary portion of the book as Collin remembers that fateful autumn in his sixteenth year when he and a few others joined Dolly in her first and only major rebellion. Capote will periodically draw the reader back to the present day as Collin shares information about his current life in context with his colorful past.
