Album

Albums of recorded music were developed in the early 20th century, first as books of individual 78rpm records, then from 1948 as vinyl LP records played at 33 ¹⁄₃ rpm. Vinyl LPs are still issued, though in the 21st century albums sales have mostly focused on compact disc (CD) and MP3 formats. The audio cassette was a format used in the late 1970s through to the 1990s alongside vinyl.

An album may be recorded in a recording studio (fixed or mobile), in a concert venue, at home, in the field, or a mix of places. Recording may take a few hours to several years to complete, usually in several takes with different parts recorded separately, and then brought or "mixed" together. Recordings that are done in one take without overdubbing are termed "live", even when done in a studio. Studios are built to absorb sound, eliminating reverberation, so as to assist in mixing different takes; other locations, such as concert venues and some "live rooms", allow for reverberation, which creates a "live" sound. The majority of studio recordings contain an abundance of editing, sound effects, voice adjustments, etc. With modern recording technology, musicians can be recorded in separate rooms or at separate times while listening to the other parts using headphones; with each part recorded as a separate track.

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."

Christmas

Christmas or Christmas Day (Old English: Crīstesmæsse, meaning "Christ's Mass") is an annual festival commemorating the birth of Jesus Christ, observed most commonly on December 25 as a religious and cultural celebration among billions of people around the world. A feast central to the Christian liturgical year, it is prepared for by the season of Advent or the Nativity Fast and initiates the season of Christmastide, which historically in the West lasts twelve days and culminates on Twelfth Night; in some traditions, Christmastide includes an Octave. Christmas Day is a public holiday in many of the world's nations, is celebrated culturally by a large number of non-Christian people, and is an integral part of the holiday season, while some Christian groups reject the celebration. In several countries, celebrating Christmas Eve on December 24 has the main focus rather than December 25, with gift-giving and sharing a traditional meal with the family.

Christmas and holiday season

The Christmas season, or festive season, (also called the holiday season or simply the holidays, mainly in the U.S. and Canada), is an annually recurring period recognized in many Western and Western-influenced countries that is generally considered to run from late November to early January, defined as incorporating at least Christmas, and usually New Year, and sometimes various other holidays and festivals. It incorporates a period of shopping which comprises a peak season for the retail sector (the "Christmas (or holiday) shopping season"), and a period of sales at the end of the season (the "January sales"). Christmas window displays and Christmas tree lighting ceremonies when trees decorated with ornaments and light bulbs are illuminated, are traditions in many areas.

Originally within the Roman Catholic Church, the term "Christmas season" was considered synonymous with Christmastide, a term associated with Yuletide, which runs from December 25 (Christmas Day) to January 6 (Epiphany), popularly known as the 12 Days of Christmas. However, as the economic impact involving the anticipatory lead-up to Christmas Day grew in America and Europe into the 19th and 20th centuries, the term "Christmas season" began to become synonymous instead with the traditional Christian Advent season, the period observed in Western Christianity from the fourth Sunday before Christmas Day until Christmas Day itself. The term "Advent calendar" survives in secular Western parlance as a term referring to a countdown to Christmas Day from the beginning of December.

New-age music

New-age music is a genre of music intended to create artistic inspiration, relaxation, and optimism. It is used by listeners for yoga, massage, meditation, and reading as a method of stress management or to create a peaceful atmosphere in their home or other environments, and is associated with environmentalism and New Age spirituality.

New age includes both electronic forms, frequently relying on sustained synth pads or long sequencer-based runs, and acoustic forms, featuring instruments such as flutes, piano, acoustic guitar and a wide variety of non-western acoustic instruments. Vocal arrangements were initially rare in new age, but as it has evolved vocals have become more common, especially vocals featuring Native American-, Sanskrit-, or Tibetan-influenced chants, or lyrics based on mythology such as Celtic legends.

New-age music was influenced by a wide range of artists from a variety of genres. Irv Teibel's Environments series (1969–79) featured natural soundscapes, tintinnabulation, and "Om" chants and were some of the first publicly available psychoacoustic recordings. In 1973, Mike Oldfield's progressive rock album Tubular Bells became one of the first albums to be referred to under the genre description of new age.Steven Halpern's 1975 Spectrum Suite was a key work that began the new-age music movement. By 1989, there were over 150 small independent record labels releasing new-age music.
