Music is generally defined as the art of arranging sound to create
some combination of form, harmony, melody, rhythm, or otherwise
expressive content.
Definitions of music vary depending on culture, though it is an aspect
of all human societies and a cultural universal. The creation of music
is commonly divided into
musical composition, musical improvisation, and
musical performance, though the topic itself extends
into academic disciplines, criticism, philosophy, psychology, and
therapeutic contexts.
