New Age

The New Age is a term applied to a range of spiritual or religious beliefs and practices that developed in Western nations during the 1970s. Precise scholarly definitions of the movement differ in their emphasis, largely as a result of its highly eclectic structure. Although analytically often considered to be religious, those involved in it typically prefer the designation of "spiritual" and rarely use the term "New Age" themselves. Many scholars of the subject refer to it as the New Age movement, although others contest this term, believing that it gives a false sense of homogeneity to the phenomenon.

As a form of Western esotericism, the New Age movement drew heavily upon a number of older esoteric traditions, in particular those that emerged from the occultist current that developed in the eighteenth century. Such prominent occult influences include the work of Emanuel Swedenborg and Franz Mesmer, as well as the ideas of Spiritualism, New Thought, and the Theosophical Society. A number of mid-twentieth century influences, such as the UFO cults of the 1950s, the Counterculture of the 1960s, and the Human Potential Movement, also exerted a strong influence on the early development of the New Age movement. Although the exact origins of the movement remain contested, it is agreed that it developed in the 1970s, at which time it was centred largely in the United Kingdom. It expanded and grew largely in the 1980s and 1990s, in particular within the United States.

Background music

Background music refers to various styles of music or soundscapes primarily intended to be passively listened to. It is not meant to be the main focus of an audience, but rather to supplement that which is meant to be focused upon. Music that is played at a low volume and is not the main focus of an audience is also referred to as background music. Traditional examples of background music include music played at various social gatherings and music played in certain retail venues. It is also common to employ background music in various electronic media including film, television, and Internet videos such as video blogs.

Psychological study

The study of background music focuses on the impact of music with non-musical tasks, including changes in behavior in the presence of different types, settings, or styles of music. In laboratory settings, music can affect performance on cognitive tasks (memory, attention, and comprehension), both positively and negatively. Used extensively as an advertising aid, music may also affect marketing strategies, ad comprehension, and consumer choices.

Music

Music is an art form and cultural activity whose medium is sound and silence. The 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 (which are sometimes termed the "color" of a musical sound). Different styles or types of music may emphasize, de-emphasize or omit some of these elements. Music is performed with a vast range of instruments and with vocal techniques ranging from singing to rapping, and there are solely instrumental pieces, solely vocal pieces and pieces that combine singing and instruments. The word derives from Greek μουσική (mousike; "art of the Muses"). In its most general form, the activities describing music as an art form include the production of works of music (songs, tunes, symphonies, and so on), the criticism of music, the study of the history of music, and the aesthetic examination of music. Ancient Greek and Indian philosophers defined music as tones ordered horizontally as melodies and vertically as harmonies. Common sayings such as "the harmony of the spheres" and "it is music to my ears" point to the notion that music is often ordered and pleasant to listen to. However, 20th-century composer John Cage thought that any sound can be music, saying, for example, "There is no noise, only sound."
