Musicis an art form consisting of sound and silence. Elements of music are pitch (which governs melody and harmony), rhythm (and its associated concepts tempo, meter, and articulation), dynamics, structure, and the sonic qualities of timbre and texture. The creation, performance, significance, and even the definition of music vary according to culture and social context. Music ranges from strictly organized compositions , through improvisational music to aleatoric forms. Music can be divided into genres and sub-genres, although the dividing lines and relationships between music genres are often subtle, sometimes open to individual interpretation, and occasionally controversial. Within "the arts", music can be classified as a performing art, a fine art, or an auditory art form.
Nature,in the broadest sense, is the natural world, physical universe, material world or material universe. "Nature" refers to the phenomena of the physical world, and also to life in general. Manufactured objects and human interaction are, in common usage, not considered part of nature unless qualified in ways such as "human nature" or "the whole of nature".Nature is generally distinguished from the supernatural. It ranges in scale from the subatomic to the galactic.
Tuning is the process of adjusting the pitch of one or many tones from musical instruments to establish typical intervals between these tones. Tuning is usually based on a fixed reference, such as A = 440 Hz. Out of tune refers to a pitch/tone that is either too high or too low, or sharp or flat, respectively. While an instrument might be in tune in it self (relative tuning) but is not on A = 440 Hz when playing with a piano or other fixed-pitch instrument nobody will agree it is in tune as it fails to match the reference pitch. Some instruments get 'out of tune' with damage or age when they will no longer play true and have to be repaired.
