expressive content. Definitions of music vary depending on culture, though
it is an aspect of all human societies and a cultural universal.
While scholars agree that music is defined by a few specific elements,

is commonly divided into musical composition, musical improvisation,
and musical performance, though the topic itself extends into academic
disciplines, criticism, philosophy, and psychology. Music may be
performed or improvised using a vast range of instruments, including
the human voice.
