Music
The most general definition of music is the arrangement of sound to create some combination of form, harmony, melody, rhythm, or otherwise expressive content.However, 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, there is no consensus on their precise definitions. 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. Music may be performed using a vast range of instruments, including the human voice to sing, and thus is often credited for its extreme versatility and opportunity for creativity.
In some musical contexts, a performance or composition may be to some extent improvised.
