Bathroom Singing
Bathroom singing, also known as singing in the bathroom, singing in the bath, or singing in the shower, is a widespread phenomenon. Many people sing in the bathroom because the hard wall surfaces, often tiles or wooden panels, and lack of soft furnishings, create an aurally pleasing acoustic environment. Scientific explanation The multiple reflections from walls enrich the sound of one's voice. Small dimensions and hard surfaces of a typical bathroom produce various kinds of standing waves, reverberation and echoes, giving the voice "fullness and depth." This habit was reported (with an attempt of explanations) centuries ago. For example, Ibn Khaldun in Chapter 1 of his ''Muqaddimah'' writes: In popular culture The bathroom singer is an ironic reference to mediocre or amateur singers. Music professionals, however, have also connected with the particular acoustices of the bathroom. Jon Anderson of Yes, for instance, had tiles installed in the studio, to simulate the echo ...

Standing Wave
In physics, a standing wave, also known as a stationary wave, is a wave that oscillates in time but whose peak amplitude profile does not move in space. The peak amplitude of the wave oscillations at any point in space is constant with respect to time, and the oscillations at different points throughout the wave are in phase. The locations at which the absolute value of the amplitude is minimum are called nodes, and the locations where the absolute value of the amplitude is maximum are called antinodes. Standing waves were first noticed by Michael Faraday in 1831. Faraday observed standing waves on the surface of a liquid in a vibrating container. Franz Melde coined the term "standing wave" (German: ''stehende Welle'' or ''Stehwelle'') around 1860 and demonstrated the phenomenon in his classic experiment with vibrating strings. This phenomenon can occur because the medium is moving in the direction opposite to the movement of the wave, or it can arise in a stationary medium ...

Singing
Singing is the act of creating musical sounds with the voice. A person who sings is called a singer, artist or vocalist (in jazz and/or popular music). Singers perform music (arias, recitatives, songs, etc.) that can be sung with or without accompaniment by musical instruments. Singing is often done in an ensemble of musicians, such as a choir. Singers may perform as soloists or accompanied by anything from a single instrument (as in art song or some jazz styles) up to a symphony orchestra or big band. Different singing styles include art music such as opera and Chinese opera, Indian music, Japanese music, and religious music styles such as gospel, traditional music styles, world music, jazz, blues, ghazal, and popular music styles such as pop, rock, and electronic dance music. Singing can be formal or informal, arranged, or improvised. It may be done as a form of religious devotion, as a hobby, as a source of pleasure, comfort, or ritual as part of music education or ...

Voice Frequency
A voice frequency (VF) or voice band is the range of audio frequencies used for the transmission of speech. Frequency band In telephony, the usable voice frequency band ranges from approximately 300 to 3400  Hz. It is for this reason that the ultra low frequency band of the electromagnetic spectrum between 300 and 3000 Hz is also referred to as ''voice frequency'', being the electromagnetic energy that represents acoustic energy at baseband. The bandwidth allocated for a single voice-frequency transmission channel is usually 4 kHz, including guard bands, allowing a sampling rate of 8 kHz to be used as the basis of the pulse-code modulation system used for the digital PSTN. Per the Nyquist–Shannon sampling theorem, the sampling frequency (8 kHz) must be at least twice the highest component of the voice frequency via appropriate filtering prior to sampling at discrete times (4 kHz) for effective reconstruction of the voice signal. Fundamental fre ...

Acoustic Resonance
Acoustic resonance is a phenomenon in which an acoustic system amplifies sound waves whose frequency matches one of its own natural frequencies of vibration (its ''resonance frequencies''). The term "acoustic resonance" is sometimes used to narrow mechanical resonance to the frequency range of human hearing, but since acoustics is defined in general terms concerning vibrational waves in matter, acoustic resonance can occur at frequencies outside the range of human hearing. An acoustically resonant object usually has more than one resonance frequency, especially at harmonics of the strongest resonance. It will easily vibrate at those frequencies, and vibrate less strongly at other frequencies. It will "pick out" its resonance frequency from a complex excitation, such as an impulse or a wideband noise excitation. In effect, it is filtering out all frequencies other than its resonance. Acoustic resonance is an important consideration for instrument builders, as most acoustic i ...

Room Modes
Room modes are the collection of resonances that exist in a room when the room is excited by an acoustic source such as a loudspeaker. Most rooms have their fundamental resonances in the 20  Hz to 200 Hz region, each frequency being related to one or more of the room's dimensions or a divisor thereof. These resonances affect the low-frequency low-mid-frequency response of a sound system in the room and are one of the biggest obstacles to accurate sound reproduction. Mechanism of room resonances The input of acoustic energy to the room at the modal frequencies and multiples thereof causes standing waves. The nodes and antinodes of these standing waves result in the loudness of the particular resonant frequency being different at different locations of the room. These standing waves can be considered a temporary storage of acoustic energy as they take a finite time to build up and a finite time to dissipate once the sound energy source has been removed. Minimizing ...

String Band
A string band is an old-time music or jazz ensemble made up mainly or solely of string instruments. String bands were popular in the 1920s and 1930s, and are among the forerunners of modern country music and bluegrass. While being active countrywide, in Philadelphia and its surrounding suburbs they are a huge part of its musical culture and traditions, appearing, among others, in the yearly Mummers Parade. History of African American old-time string band music Although African American old-time string bands recorded history is that of the early 20th century, the beginnings of the music started much earlier. Many people once believed that the role African Americans played in the upcoming of old-time string band music was either nonexistent or to interest the middle ages or medieval times. The genre of African American folk music actually began with the use of percussion instruments, which were used to create music in form of encouragement to keep the slaves exercising on slave ...

Retro Style
Retro style is imitative or consciously derivative of lifestyles, trends, or art forms from history, including in music, modes, fashions, or attitudes. In popular culture, the "nostalgia cycle" is typically for the two decades that begin 20–30 years ago. Definition The term ''retro'' has been in use since 1972 to describe on the one hand, new artifacts that self-consciously refer to particular modes, motifs, techniques, and materials of the past. But on the other hand, many people use the term to categorize styles that have been created in the past. Retro style refers to new things that display characteristics of the past. Unlike the historicism of the Romantic generations, it is mostly the recent past that retro seeks to recapitulate, focusing on the products, fashions, and artistic styles produced since the Industrial Revolution, the successive styles of Modernity. The English word ''retro'' derives from the Latin prefix ''retro'', meaning backwards, or in past times. In Fra ...

Milk Bar Clubnight
Nicky Holloway (born 12 June 1963) is an English DJ and record producer, who rose to fame in the 1980s and 1990s, and has been called "a prototype of the superstar DJ". Biography Nicholas Holloway was born in Isleworth, London. He began playing records in the disco pub scene around the Old Kent Road in 1980. He first started to organise club nights, such as Special Branch in London Bridge in 1984 alongside Pete Tong and Gilles Peterson. Holloway (with Paul Oakenfold, Johnny Walker and Danny Rampling) was one of the "Ibiza four" - four DJs who travelled to the island for a holiday in the summer of 1987. They visited a club called Amnesia and met an Argentine DJ called Alfredo Fiorito, who inspired them to promote Balearic beats back in the UK. Holloway opened the clubnight Trip at the London Astoria in Charing Cross Road at the end of May 1988, and was one of the first legal acid house clubs. Trip changed its name to Sin, after the previous name's close association with drug ...
