ABSTRACT
The most outspoken definition of modern music is found in Key to Musicianship by Christine Trotin, published in New York in 1927:
“Modern music seems to be the product of a revolt undertaken by a certain group of musicians against any rule whatsoever and reflects the trend of thought in the present generation. It is supposed to be based on what is called the ‘whole-tone scale,’ which explains the frequency of the discords, which, at times, follow each other in the most distressing manner.”
