Music is an art form and cultural activity whose medium is sound. Common elements of music are pitch (which governs melody and harmony), rhythm (and its associated concepts tempo, meter, and articulation), dynamics (loudness and softness), and the sonic qualities of timbre and texture.

Music can be categorized in many different ways, such as genres (e.g., classical, pop, country, jazz) or styles. It can be performed or created using a wide range of instruments and vocal techniques, ranging from singing to rapping.

The creation, performance, significance, and even the definition of music vary according to culture and social context. Music ranges from strictly organized compositions (and their recreation in performance), through improvisational music to aleatoric forms.

• Performance: Music is typically performed live or recorded, and can be enjoyed by individuals or large audiences.
• Creation: Music can be created by composing, improvising, or arranging existing pieces.
• Significance: Music can express emotions, tell stories, or serve religious, ceremonial, or entertainment purposes.
