Gramophone record

A gramophone record (phonograph record in American English) or vinyl record, commonly known as a "record", is an analog sound storage medium in the form of a flat polyvinyl chloride (previously shellac) disc with an inscribed, modulated spiral groove. The groove usually starts near the periphery and ends near the center of the disc. Phonograph records are generally described by their diameter in inches (12", 10", 7"), the rotational speed in rpm at which they are played (16 ²⁄₃, 33 ¹⁄₃, 45, 78), and their time capacity resulting from a combination of those parameters (LP – long playing 33 ¹⁄₃ rpm, SP – 78 rpm single, EP – 12-inch single or extended play, 33 or 45 rpm); their reproductive quality or level of fidelity (high-fidelity, orthophonic, full-range, etc.), and the number of audio channels provided (mono, stereo, quad, etc.).

The phonograph disc record was the primary medium used for music reproduction until late in the 20th century, replacing the phonograph cylinder record, with which it had co-existed, by the 1920s. By the late 1980s, digital media, in the form of the compact disc, had gained a larger market share, and the vinyl record left the mainstream in 1991. After its fall, records continued to be manufactured and sold, and have been especially used by disc jockeys and many audiophiles for various types of music. The phonograph record has made a niche resurgence in the early 21st century – 9.2 million records were sold in the U.S. in 2014, a 260% increase since 2009. Likewise, in the UK sales have increased five-fold from 2009 to 2014.

Acoustic guitar

An acoustic guitar is a guitar that produces sound acoustically—by transmitting the vibration of the strings to the air—as opposed to relying on electronic amplification (see Electric guitar). The sound waves from the strings of an acoustic guitar resonate through the guitar's body, creating sound. This typically involves the use of a sound board and a sound box to strengthen the vibrations of the strings.

The main source of sound in an acoustic guitar is the string, which is plucked or strummed with the finger or with a plectrum. The string vibrates at a necessary frequency and also create many harmonics at various different frequencies. The frequencies produced can depend on string length, mass, and tension. The string causes the soundboard and sound box to vibrate, and as these have their own resonances at certain frequencies, they amplify some string harmonics more strongly than others, hence affecting the timbre produced by the instrument.

History

Gitterns, a small plucked guitar were the first small like guitar instruments created during the Middle Ages with a round back like that of a lute. Guitar like shaped instruments were not seen until the Renaissance era where the body and size began to take a guitar like shape.

Consolers of the Lonely

Consolers of the Lonely is the second album by American rock band The Raconteurs. It was released on March 25, 2008 on Warner Bros. Records in most parts of the world, and a day earlier on XL Recordings in the UK.

The band did no promotion before the album's release, and its existence was only confirmed a week before. Even so, the record was accidentally leaked by iTunes, and some fans managed to purchase the album early. It is available on CD, vinyl, and MP3. A video for the first single from the album, "Salute Your Solution" was released on the same day. The album earned a nomination for Best Rock Album at the 51st Grammy Awards.

Background

The band premiered "Five on the Five" during their last tour. The title of the record comes from the inscription in the side of a Washington, D.C. post office written by Charles William Eliot, which reads in full:

Messenger of sympathy and love, servant of parted friends, consoler of the lonely, bond of the scattered family, enlarger of the common life.
