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."

Spa

A spa is a location where mineral-rich spring water (and sometimes seawater) is used to give medicinal baths. Spa towns or spa resorts (including hot springs resorts) typically offer various health treatments, which are also known as balneotherapy. The belief in the curative powers of mineral waters goes back to prehistoric times. Such practices have been popular worldwide, but are especially widespread in Europe and Japan. Day spas are also quite popular, and offer various personal care treatments.

Origins of the term

The term is derived from the name of the town of Spa, Belgium, whose name is known back to Roman times, when the location was called Aquae Spadanae, sometimes incorrectly connected to the Latin word “spargere” meaning to scatter, sprinkle or moisten. Since medieval times, illnesses caused by iron deficiency were treated by drinking chalybeate (iron-bearing) spring water (in 1326, the ironmaster Collin le Loup claimed a cure, when the spring was called Espa, a Walloon word for "fountain").

Instrumental

An instrumental is a musical composition or recording without lyrics, or singing, although it might include some inarticulate vocal input; the music is primarily or exclusively produced by musical instruments.

In a song that is otherwise sung, a section not sung but played with instruments can be called an instrumental interlude. If the instruments are percussion instruments, the interlude can be called a percussion interlude. These interludes are a form of break in the song.

In popular music

In commercial popular music, instrumental tracks are sometimes renderings of a corresponding release that features vocals, but they may also be compositions originally conceived without vocals. An instrumental version of a song which otherwise features vocals is also known as a -1 (pronounced minus one).

The opposite of instrumental music is a cappella.

For genres in which a non-vocal song or interlude is conceived using electronic media, rather than with true musical instruments, the term instrumental is nonetheless used for it.

Classical music

Classical music is art music produced or rooted in the traditions of Western music, including both liturgical (religious) and secular music. While a similar term is also used to refer to the period from 1750-1820 (the Classical period), this article is about the broad span of time from roughly the 11th century to the present day, which includes the Classical period and various other periods. The central norms of this tradition became codified between 1550 and 1900, which is known as the common practice period. The major time divisions of classical music are as follows: the early music period, which includes the Medieval (500–1400) and the Renaissance (1400–1600) eras; the Common practice period, which includes the Baroque (1600–1750), Classical (1750–1820), and Romantic eras (1804–1910); and the 20th century (1901–2000) which includes the modern (1890–1930) that overlaps from the late 19th-century, the high modern (mid 20th-century), and contemporary or postmodern (1975–2015) eras.

Reiki

Reiki (/ˈreɪkiː/) is a form of alternative medicine developed in 1922 by Japanese Buddhist Mikao Usui. Since its beginning in Japan, Reiki has been adapted across varying cultural traditions. It uses a technique commonly called palm healing or hands-on-healing. Through the use of this technique, practitioners believe that they are transferring "universal energy" through the palms of the practitioner, which they believe encourages healing.

Reiki is considered pseudoscience. It is based on qi ("chi"), which practitioners say is a universal life force, although there is no empirical evidence that such a life force exists. Clinical research has not shown Reiki to be effective as a medical treatment for any medical condition. The American Cancer Society,Cancer Research UK, and the National Center for Complementary and Integrative Health state that Reiki should not be a replacement for conventional treatment of diseases such as cancer.

Etymology

According to the OED, the English alternative medicine word reiki or Reiki is etymologically from Japanese reiki (霊気) "mysterious atmosphere, miraculous sign" (first recorded in 1001), combining rei "soul, spirit" and ki "vital energy"—the Sino-Japanese reading of Chinese língqì (靈氣) "numinous atmosphere". The earliest recorded English usage dates to 1975.
