I'm looking for books/textbooks, maybe an anthology regarding composer styles for piano. I'd like a good source, a well-researched book, so I can turn to it whenever I need to review compositional styles (i.e. performing Debussy, stylistic comments). There are some authors who have researched and written about one composer in great detail - I'd be interested in those. I'd like to mainly invest in a good home library, the books that are essential for any pianist, teacher, theorist; AND from a performance point of view. Open to your suggestions
