Why did Goldsworthy write ‘Maestro’ as a reflective memoir?

The book draws on many biographical details from Goldsworthy's life. Like Paul, Goldsworthy is originally from Southern Australia, but finished high school in Darwin before attending the University of Adelaide. His daughter Anna Goldsworthy is a classical pianist. He dedicates the book to Anna, his parents Jan and Reuben, and to Anna's childhood piano teacher, Eleanora Sivan. Anna considers Sivan a central guide and inspiration, and their relationship likely inspired Paul and Keller's relationship in Goldsworthy's novel.
