I've written sixteen books about classical music thus far. The vast majority (13) are guides to various composers, currently published by Rowman and Littlefield. You can find and purchase them here: https://rowman.com/Action/Search/_/da...
Topics covered include Beethoven, Brahms, Haydn, Mozart, Mahler, Sibelius, Shostakovich, Handel, Bernstein, Mendelssohn, Dvořák, Richard Strauss, and CPE Bach. I am proud of these works, and I hope you will consider checking them out if these composers arouse your curiosity.
