Violin
The violin, also known informally as a fiddle, is a wooden string instrument in the violin family. Most violins have a hollow wooden body. It is the smallest and highest-pitched instrument in the family in regular use. Smaller violin-type instruments are known, including the violino piccolo and the kit violin, but these are virtually unused. The violin typically has four strings tuned in perfect fifths, and is most commonly played by drawing a bow across its strings, though it can also be played by plucking the strings with the fingers (pizzicato) and by striking the strings with the wooden side of the bow (col legno).
Double bass
The double bass, or simply the bass (and numerous other names), is the largest and lowest-pitched bowed string instrument in the modern symphony orchestra. It is a transposing instrument and is typically notated one octave higher than tuned to avoid excessive ledger lines below the staff. The double bass is the only modern bowed string instrument that is tuned in fourths (like a viol), rather than fifths, with strings usually tuned to E, A, D and G. The instrument's exact lineage is still a matter of some debate, with scholars divided on whether the bass is derived from the viol or the violin family.
Six Sonatas for Violin and Harpsichord, BWV 1014–1019
The six sonatas for violin and obbligato harpsichord BWV 1014–1019 by Johann Sebastian Bach are works in trio sonata form, with the two upper parts in the harpsichord and violin over a bass line supplied by the harpsichord and an optional viola da gamba. Unlike baroque sonatas for solo instrument and continuo, where the realisation of the figured bass was left to the discretion of the performer, the keyboard part in the sonatas was almost entirely specified by Bach. They were probably mostly composed during Bach's final years in Cöthen between 1720 and 1723, before he moved to Leipzig. The extant sources for the collection span the whole of Bach's period in Leipzig, during which time he continued to make changes to the score.
Gajananrao Joshi
Gajanan Anant Joshi also Gajananbuwa Joshi (30 January 1911 – 1987) was a unique and versatile vocalist and a renowned violinist in the field of Hindustani music. Pandit Gajananrao Joshi also known, respectfully and affectionately, as Gajananbuwa Joshi came from a family of musicians. His grandfather Manohar had studied dhrupad and dhamar, and his father Anant Manohar Joshi was a distinguished khayal singer who had studied under Balakrishnabuwa Ichalkaranjikar. Gajananbuwa studied "gayaki" of Gwalior gharana under his father and also under other teachers in whom he found something to learn, and assimilated other styles in his art.
Keyboard concertos by Johann Sebastian Bach
The harpsichord concertos, BWV 1052–1065, are concertos for harpsichord, strings and continuo by Johann Sebastian Bach. There are seven complete concertos for a single harpsichord (BWV 1052–1058), three concertos for two harpsichords (BWV 1060–1062), two concertos for three harpsichords (BWV 1063 and 1064), and one concerto for four harpsichords (BWV 1065). Two other concertos include solo harpsichord parts: the concerto BWV 1044, which has solo parts for harpsichord, violin and flute, and "Brandenburg Concerto" No. 5 in D major, with the same scoring. In addition, there is a nine-bar concerto fragment for harpsichord (BWV 1059) which adds an oboe to the strings and continuo.
Chamber music
Chamber music is a form of classical music that is composed for a small group of instruments—traditionally a group that could fit in a palace chamber or a large room. Most broadly, it includes any art music that is performed by a small number of performers, with one performer to a part (in contrast to orchestral music, in which each string part is played by a number of performers). However, by convention, it usually does not include solo instrument performances. Because of its intimate nature, chamber music has been described as "the music of friends". For more than 100 years, chamber music was played primarily by amateur musicians in their homes, and even today, when chamber music performance has migrated from the home to the concert hall, many musicians, amateur and professional, still play chamber music for their own pleasure.
Edward Elgar
Sir Edward William Elgar, 1st Baronet (2 June 1857 – 23 February 1934) was an English composer, many of whose works have entered the British and international classical concert repertoire. Among his best-known compositions are orchestral works including the "Enigma Variations", the "Pomp and Circumstance Marches", concertos for violin and cello, and two symphonies. He also composed choral works, including "The Dream of Gerontius", chamber music and songs. He was appointed Master of the King's Musick in 1924. Although Elgar is often regarded as a typically English composer, most of his musical influences were not from England but from continental Europe.

Keyboard amplifier
A keyboard amplifier is a powered electronic amplifier and loudspeaker in a wooden speaker cabinet used for amplification of electronic keyboard instruments. Keyboard amplifiers are distinct from other types of amplification systems such as guitar amplifiers due to the particular challenges associated with making keyboards sound louder on stage; namely, to provide solid low-frequency sound reproduction for the deep basslines which keyboards can play "and" crisp high-frequency sound for the high-register notes. Another difference between keyboard amplifiers and guitar/bass amplifiers is that keyboard amps are usually designed with a relatively flat frequency response and low distortion.
Bass amplifier
A bass amplifier or "bass amp" is a musical instrument electronic device that uses electrical power to make lower-pitched instruments such as the bass guitar or double bass loud enough to be heard by the performers and audience. Bass amps typically consist of a preamplifier, tone controls, a power amplifier and one or more loudspeakers ("drivers") in a cabinet. While bass amps share many features with the guitar amplifiers used for electric guitar, such as providing an amplifier with tone and volume controls and a carrying handle, they are distinct from other types of amplification systems, due to the particular challenges associated with low-frequency sound reproduction.
Guitar amplifier
A guitar amplifier (or amp) is an electronic device or system that strengthens the weak electrical signal from a pickup on an electric guitar, bass guitar, or acoustic guitar so that it can produce sound through one or more loudspeakers, which are typically housed in a wooden cabinet. A guitar amplifier may be a standalone wood or metal cabinet that contains only the power amplifier (and preamplifier) circuits, requiring the use of a separate speaker cabinet–or it may be a "combo" amplifier, which contains both the amplifier and one or more speakers in a wooden cabinet. There is a wide range of sizes and power ratings for guitar amplifiers, from small, lightweight "practice amplifiers" with a single 6" speaker to heavy combo amps with four 10” or four 12" speakers and a powerful amplifier, which are loud enough to use in a nightclub or bar performance.
Piano
The piano is an acoustic, stringed musical instrument invented in Italy by Bartolomeo Cristofori around the year 1700 (the exact year is uncertain), in which the strings are struck by hammers. It is played using a keyboard, which is a row of keys (small levers) that the performer presses down or strikes with the fingers and thumbs of both hands to cause the hammers to strike the strings. The word "piano" is a shortened form of "pianoforte", the Italian term for the early 1700s versions of the instrument, which in turn derives from "gravicembalo col piano e forte" and "fortepiano". The Italian musical terms "piano" and "forte" indicate "soft" and "loud" respectively, in this context referring to the variations in volume (i.e., loudness) produced in response to a pianist's touch or pressure on the keys: the greater the velocity of a key press, the greater the force of the hammer hitting the strings, and the louder the sound of the note produced and the stronger the attack.
Instrument amplifier
An instrument amplifier is an electronic device that converts the often barely audible or purely electronic signal of a musical instrument into an audible sound. An instrument amplifier is used with musical instruments such as an electric guitar, an electric bass, electric organ, synthesizers and drum machine to convert the signal from the pickup (with guitars and other string instruments and some keyboards) or other sound source (e.g, a synthesizer's signal) into an electronic signal that has enough power, due to being routed through a power amplifier, capable of driving one or more loudspeaker that can be heard by the performers and audience.
CuriOdyssey
CuriOdyssey, formerly Coyote Point Museum for Environmental Education, and Coyote Point Museum, is an experiential science and wildlife center for children and families. Located at 1651 Coyote Point Drive in San Mateo, California, it is part of the Coyote Point Recreation Area, which overlooks the San Francisco Bay. The museum was founded in 1954 as the San Mateo County Junior Museum, and is accredited by the Association of Zoos and Aquariums (AZA). The animals at CuriOdyssey are all injured or imprinted in such a way that they would not survive in the wild. Most of the animals are native to California, though there are some animals that are housed here as part of the museum's Animal Ambassador program.
Electronic keyboard
An electronic keyboard or digital keyboard is an electronic musical instrument, an electronic or digital derivative of keyboard instruments. Broadly speaking, in a popular music context, the term "electronic keyboard" or just a "keyboard" mostly refers to any type of digital or electronic keyboard instrument. These include synthesizers, digital pianos, stage pianos, electronic organs and digital audio workstations. However, in true musical terminology, an electronic keyboard is an inexpensive synthesizer equipped with built-in power amplifier and small loudspeakers. Electronic keyboards are capable of recreating a wide range of instrument sounds (piano, electric piano, Hammond organ, pipe organ, violin, etc.)

Comparison of analog and digital recording
Sound can be recorded and stored and played using either digital or analog techniques. Both techniques introduce errors and distortions in the sound, and these methods can be systematically compared. An analog recording is one where a property or characteristic of a physical recording medium is made to vary in a manner analogous to the variations in air pressure of the original sound. Generally, the air pressure variations are first converted (by a transducer such as a microphone) into an electrical analog signal in which either the instantaneous voltage or current is analogous to the instantaneous air pressure.
LaserDisc
LaserDisc (abbreviated as LD) is a home video format and the first commercial optical disc storage medium, initially licensed, sold and marketed as MCA DiscoVision in North America in 1978. Although the format was capable of offering higher-quality video and audio than its consumer rivals, VHS and Betamax videotape, LaserDisc never managed to gain widespread use in North America, largely due to high costs for the players and video titles themselves and the inability to record TV programs. It was not a popular format in Europe and Australia when first released, but eventually did gain traction in these regions to become popular in the 1990s.
History of sound recording
Experiments in capturing sound on a recording medium for preservation and reproduction began in earnest during the Industrial Revolution of the 1800s. Many pioneering attempts to record and reproduce sound were made during the latter half of the 19th century – notably Scott's Phonautograph of 1857 – and these efforts culminated in the invention of the phonograph by Thomas Edison in 1877. Digital recording emerged in the late 20th century, and has since flourished with the popularity of digital music and online streaming services. The history of sound recording - which has progressed in waves, driven by the invention and commercial introduction of new technologies — can be roughly divided into four main periods:  The earliest practical recording technologies were entirely mechanical devices.
Oscilloscope types
This is a subdivision of the Oscilloscope article, discussing the various types and models of oscilloscopes in greater detail. While analog devices make use of continually varying voltages, digital devices employ binary numbers which correspond to samples of the voltage. In the case of digital oscilloscopes, an analog-to-digital converter (ADC) is used to change the measured voltages into digital information. Waveforms are taken as a series of samples. The samples are stored, accumulating until enough are taken in order to describe the waveform, which are then reassembled for display. Digital technology allows the information to be displayed with brightness, clarity, and stability.
Synthesizer
A synthesizer (often abbreviated as synth, also spelled synthesiser) is an electronic musical instrument that generates electric signals that are converted to sound through instrument amplifiers and loudspeakers or headphones. Synthesizers may either imitate traditional musical instruments like piano, Hammond organ, flute, vocals; natural sounds like ocean waves, etc. ; or generate novel electronic timbres. They are often played with a musical keyboard, but they can be controlled via a variety of other input devices, including music sequencers, instrument controllers, fingerboards, guitar synthesizers, wind controllers, and electronic drums.
Phonograph record
A phonograph record (also known as a gramophone record, especially in British English, or record) is an analog sound storage medium in the form of a flat disc with an inscribed, modulated spiral groove. The groove usually starts near the periphery and ends near the center of the disc. At first, the discs were commonly made from shellac; starting in the 1950s polyvinyl chloride became common. In recent decades, records have sometimes been called vinyl records, or simply vinyl, although this would exclude most records made until after World War II. The phonograph disc record was the primary medium used for music reproduction until late in the 20th century.
Radioteletype
Radioteletype (RTTY) is a telecommunications system consisting originally of two or more electromechanical teleprinters in different locations connected by radio rather than a wired link. These machines were superseded by personal computers (PCs) running software to emulate teleprinters. Radioteletype evolved from earlier landline teleprinter operations that began in the mid-1800s. The US Navy Department successfully tested printing telegraphy between an airplane and ground radio station in 1922. Later that year, the Radio Corporation of America successfully tested printing telegraphy via their Chatham, Massachusetts, radio station to the R.M.S.

Klavierstücke (Stockhausen)
The Klavierstücke (German for "Piano Pieces") constitute a series of nineteen compositions by German composer Karlheinz Stockhausen. Stockhausen has said the "Klavierstücke" "are my "drawings"" . Originating as a set of four small pieces composed between February and June 1952 , Stockhausen later formulated a plan for a large cycle of 21 "Klavierstücke", in sets of 4 + 6 + 1 + 5 + 3 + 2 pieces (; ). He composed the second set in 1954–55 ("VI" was subsequently revised several times and "IX" and "X" were finished only in 1961), and the single "Klavierstück XI" in 1956. Beginning in 1979, he resumed composing "Klavierstücke" and finished eight more, but appears to have abandoned the plan for a set of 21 pieces.
She Loves You
"She Loves You" is a song written by John Lennon and Paul McCartney and recorded by English rock group the Beatles for release as a single in 1963. The single set and surpassed several records in the United Kingdom charts, and set a record in the United States as one of the five Beatles songs that held the top five positions in the charts simultaneously, on 4 April 1964. It is their best-selling single and the best selling single of the 1960s in the United Kingdom. In November 2004, "Rolling Stone" ranked "She Loves You" number 64 on their list of the 500 Greatest Songs of All Time. In August 2009, at the end of its "Beatles Weekend", BBC Radio 2 announced that "She Loves You" was the Beatles' all-time best-selling single in the UK based on information compiled by The Official Charts Company.
2000s in music
This article includes an overview of the major events and trends in popular music in the 2000s. The 2000s saw the creation or emergence of a few styles, such as indie-related genres such as Emo, Alternative R&B, and a multitude of new electronic subgenres, most notably Dubstep, Bass music and Moombahton, as well as genres that fused influences from past decades, mostly the 80s, into creating new styles such as Nu-disco and Hypnagogic pop. In fact convergence of different styles was one of the more defining features of the decade, as seen with the creation and commercial success of the British Grime genre and Trap music and Chillwave in the United States.
21st century skills
21st century skills comprise skills, abilities, and learning dispositions that have been identified as being required for success in 21st century society and workplaces by educators, business leaders, academics, and governmental agencies. This is part of a growing international movement focusing on the skills required for students to master in preparation for success in a rapidly changing, digital society. Many of these skills are also associated with deeper learning, which is based on mastering skills such as analytic reasoning, complex problem solving, and teamwork. These skills differ from traditional academic skills in that they are not primarily content knowledge-based.
21st-century classical music
21st-century classical music is art music, in the contemporary classical tradition, that has been produced since the year 2000. Some elements of the previous century have been retained, including postmodernism, polystylism and eclecticism, which seek to incorporate elements of all styles of music irrespective of whether these are "classical" or not—these efforts represent a slackening differentiation between the various musical genres. Important influences include rock, pop, jazz and the dance traditions associated with these. The combination of classical music and multimedia is another notable practice in the 21st century; the Internet, alongside its related technology, are important resources in this respect.
Entertainment
Entertainment is a form of activity that holds the attention and interest of an audience, or gives pleasure and delight. It can be an idea or a task, but is more likely to be one of the activities or events that have developed over thousands of years specifically for the purpose of keeping an audience's attention. Although people's attention is held by different things, because individuals have different preferences in entertainment, most forms are recognisable and familiar. Storytelling, music, drama, dance, and different kinds of performance exist in all cultures, were supported in royal courts, developed into sophisticated forms and over time became available to all citizens.
Music of Cuba
The music of Cuba, including its instruments, performance and dance, comprises a large set of unique traditions influenced mostly by west African and European (especially Spanish) music. Due to the syncretic nature of most of its genres, Cuban music is often considered one of the richest and most influential regional musics of the world. For instance, the son cubano merges an adapted Spanish guitar (tres), melody, harmony, and lyrical traditions with Afro-Cuban percussion and rhythms. Almost nothing remains of the original native traditions, since the native population was exterminated in the 16th century.
