Context_1 : Accompaniment is the musical parts which provide the rhythmic and/or harmonic support for the melody or main themes of a song or instrumental piece. There are many different styles and types of accompaniment in different genres and styles of music. In homophonic music, the main accompaniment approach used in popular music, a clear vocal melody is supported by subordinate chords. In popular music and traditional music, the accompaniment parts typically provide the "beat" for the music and outline the chord progression of the song or instrumental piece. The accompaniment for a vocal melody or instrumental solo can be played by a single musician playing an instrument such as piano, pipe organ, or guitar. While any instrument can in theory be used as an accompaniment instrument, keyboard and guitar-family instruments tend to be used if there is only a single instrument, as these instruments can play chords and basslines simultaneously (chords and a bassline are easier to play simultaneously on keyboard instruments, but a fingerpicking guitarist can play chords and a bassline simultaneously on guitar). A solo singer can accompany herself by playing guitar or piano while she sings, and in some rare cases, a solo singer can even accompany himself or herself just using his or her voice and body (e.g., Bobby McFerrin). Context_2 : Vladimir Oiunovich Oidupaa (Russian: Владимир Ойунович Ойдупаа , Tuvan: Ойдупаа Владимир Ойун оглу, "Oidupaa Vladimir Oiun oglu" ] , 6 September 1949 – 25 September 2013) was a Tuvan musician, who performed Kargyraa and played bayan. He is considered one of the leading figures in the contemporary Tuvan music. Context_3 : Music lessons are a type of formal instruction in playing a musical instrument or singing. Typically, a student taking music lessons meets a music teacher for one-on-one training sessions ranging from 30 minutes to one hour in length over a period of weeks or years. For vocal lessons, teachers show students how to sit or stand and breathe, and how to position the head, chest, and mouth for good vocal tone. For instrument lessons, teachers show students how to sit or stand with the instrument, how to hold the instrument, and how to manipulate the fingers and other body parts to produce tones and sounds from the instrument. Music teachers also assign technical exercises, musical pieces, and other activities to help the students improve their musical skills. While most music lessons are one-on-one (private), some teachers also teach groups of two to four students (semi-private lessons), and, for very basic instruction, some instruments are taught in large group lessons, such as piano and acoustic guitar. Since the widespread availability of high speed. low latency Internet, private lessons can also take place through live video chat using webcams, microphones and videotelephony online. Context_4 : Ellipsoidal reflector spotlight (abbreviated to ERS, or colloquially ellipsoidal or ellipse) is the name for a type of stage lighting instrument, named for the ellipsoidal reflector used to collect and direct the light through a barrel that contains a lens or lens train. The optics of an ERS instrument are roughly similar to those of a 35 mm slide projector. There are many types of ERS that are designed for the myriad applications found in the entertainment industry. ERS instruments come in all shapes and sizes. Each particular model of ERS has its own set of characteristics. Generally, ERS instruments are the most varied and utilized type of stage lighting instrument. ERS may also be referred to as Profile Spotlights (especially in Europe) because the beam can be shaped to the profile of an object. Ellipsoidal reflectors are used for their strong, well-defined light and their versatility. "Leko" and "Source Four" are brand names which are often, but inaccurately, used to refer to any sort of ellipsoidal. Context_5 : In theatrical productions, an instrument schedule is a listing of all the lighting instruments and information about them used in a show. The instruments are organized by their position on-stage, and is the distinguishing characteristic between an instrument schedule and a channel hookup or similar paperwork. The instrument schedule includes all information about every instrument, including hanging location, instrument number, type, wattage, color, focus area, circuit, dimmer and templates, along with any additional information. The variety of information included in an instrument schedule generally makes this more "complete" than other generated paperwork, and as such the schedule is often considered the "master" sheet. The master electrician uses the information contained in the instrument schedule along with the light plot to direct the hanging of the instruments. Context_6 : The English guitar or guittar (also citra), is a stringed instrument – a type of cittern, which was popular in many places in Europe from around 1750–1850. It is unknown when the identifier 'English' became connected to the instrument at the time of its introduction to Great Britain, and during its period of popularity it was apparently simply known as "guitar" or "guittar". The instrument was also known in Norway as a "guitarre" and France as "cistre" or "guitarre allemande" (German guitar). There are many examples in Norwegian museums, like the Norsk Folkemuseum and British; including the Victoria and Albert Museum. The English guitar has a pear-shaped body, a flat base, and a short neck. The instrument is also related to the Portuguese guitar and the German waldzither. Context_7 : The stock-and-horn was a traditional instrument of the Scottish peasantry, very similar to the Welsh pibgorn, consisting of a single-reed reed pipe amplified by a bell made of horn. The original instrument of the Middle Ages had a double chanter with single reeds but was replaced by the single chanter type. The single chanter instrument is described in great detail by Robert Burns in a 1794 letter to a contemporary; Burns describes how he had much difficulty coming by the instrument, and notes that it has six or seven fingerholes on the top, one on the back, and is played with a single reed ("oaten reed") unfixed to the instrument but held by the lips. Context_8 : Stabule (stebule, stabuļa) is a national woodwind musical instrument of Latvia. The name can apply to variety of wind instruments, but in general sense it is a pipe with 4-8 finger holes. These instruments are 1.5-2.5 cm in diameter and can be anywhere from 20 to 40 cm in length. Stabules have either fipple or reed. Reed stabules were usually made from wood or reed with mouthpiece also made either from reed or wood. Fipple stabules were usually made of wood, although in some areas clay and bark stabules of this type were made and bone stabules have been found by archaeologists. A similar more simple type of stabule without finger holes can be made from willow bark. This type of instrument differs in that its end (opposite to mouthpiece) is plugged. The plug is generally meant for tuning the stabule, but sometimes also used as a slide to adjust tone while playing. All bark stabules were usually made in spring when bark is looser - the features of the stabule are carved right on a fresh broom of willow and the bark is then slid off; the remaining branch is then used to make the fipple and, for the simpler type of stabules, the plug. Due to the natural shrinkage of bark they were short-lived. Context_9 : The Theotokos of Vladimir (Greek: Θεοτόκος του Βλαντίμιρ ), also known as Our Lady of Vladimir, Vladimir Mother of God, or Virgin of Vladimir (Russian: Владимирская Икона Божией Матери ) is a medieval Byzantine icon of the Virgin and Child. In 1169 Andrei Bogolyubsky sacked Kiev, and, after plundering the city, stole much religious artwork, including a Byzantine "Mother of God" icon which was transferred to Vladimir (for references see Yury Dolgorukiy and Andrey Bogolyubskiy). It is one of the most venerated Orthodox icons and a fine and early example of the iconography of the "Eleusa" (tenderness) type, with the Christ child snuggling up to his mother's cheek. The "Theotokos" (Greek for Virgin Mary, literally meaning "Birth-Giver of God") is regarded as the holy protectress of Russia. The icon is displayed in the Tretyakov Gallery, Moscow in a functioning church in the grounds of the museum. Her feast day is June 23rd o.s. / July 6th n.s. Even more than most famous icons, the original has been copied repeatedly for centuries, and many copies have considerable artistic and religious significance of their own.
