The early years of Filipino classical music during the late-Spanish and early-American period were less given attention compared to the times of Nicanor Abelardo onwards. Although recently, studies on composers from this early era (1869-1916) of music such as Jose Estella, Marcelo Adonay, and Julio Nakpil were being researched and published.
One composer from this era stood out to me for some reason. His name is Teodoro Araullo. Like other composers from this period, he was a composer of marches and waltzes. However, despite his almost total obscurity today, he is actually one of the most popular composers from the early American period, rivaled only by Jose Estella. For that reason, he might just be the "Prince" of Filipino Waltzes, but that's just an informal title by me!
