1871–1918
Best known for bringing a practical, analytical approach to vocal training, this early-20th-century singing teacher wrote books that aimed to make voice study clearer and more self-directed. His work still turns up in reprints and digital archives for readers interested in the history of singing instruction.

by David C. (David Clark) Taylor
David C. Taylor, also listed as David Clark Taylor, was an American writer on singing and voice culture active in the early 1900s. The available records found here connect him most clearly with The Psychology of Singing (1908), a book that presents vocal training in a systematic, reasoned way rather than as a set of vague traditions.
A later record also credits him with Self Help for Singers (1914), suggesting a continuing interest in helping students understand and manage their own vocal development. His books remain of interest mainly to singers, teachers, and readers curious about older methods of music instruction.
I could confirm his name form and book attributions, but I did not find a strong, well-sourced biographical profile with fuller personal details such as birthplace, career milestones, or a reliable portrait on a page I could verify. Because of that, this overview keeps to the parts that could be supported.
