Abstract
By about 1890, the major dominant ninth harmony had become firmly established in compositional and improvisational practice. After 1900, this harmony was routinely used in many musical genres. The two parts of this essay sample a few of these occurrences in repertoires ranging from those that are surprisingly conservative (American marches and ragtime) to those that are remarkably adventurous (French Impressionists and the English and American musicians influenced by them). Composers represented in Part 1 include Costa Nogueras, Friml, Hageman, Herbert, Joplin, Kern, Lehar, Lincke, MacDowell, and Sousa.
