Question: A term used by music theorists to describe the profound stylistic changes of italian and french music in the 14th century.

The term used by music theorists to describe the profound stylistic changes of Italian and French music in the 14th century is Ars Nova. Ars Nova literally means "new art" in Latin. It was a period of musical innovation that was characterized by the development of new rhythmic and melodic techniques, as well as the use of more complex musical textures.

Some of the key features of Ars Nova music include:

The use of measured rhythm, which means that the duration of each note is precisely indicated.
The development of polyphonic textures, in which multiple independent melodic lines are played or sung at the same time.
The use of dissonant intervals, which are intervals that create a sense of tension or unease.
The development of new musical forms, such as the motet and the ballata.

Ars Nova music was a major turning point in the history of Western music. It helped to pave the way for the Renaissance, which was a period of even greater musical innovation and creativity.

Some of the most famous composers of Ars Nova music include:
