Angel Musicians (National Gallery)
The Angel musicians are two paintings created in the late 15th century to frame Leonardo da Vinci's ''Virgin of the Rocks''. Their purpose was to decorate the side panels of the Altarpiece in the Chapel of the Immaculate Conception, created to decorate a chapel in the Church of San Francesco Grande in Milan. Separated from their original altarpiece at the very end of the 18th century, they have been in the National Gallery in London since 1898. Both paintings are dated between 1495 and 1499. The first is entitled ''Angel in Green with a Vielle''; it has long been attributed to the Italian Renaissance painter Giovanni Ambrogio de Predis, but recent research shows that it may instead be due to Francesco Napoletano, one of Leonardo da Vinci's pupils. The second, entitled Angel in Red with lute, is generally attributed to Giovanni Ambrogio de Predis, Ambrogio de Predis. The influence of Leonardo da Vinci is evident in the treatment of these classical figures. Although the two painti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vielle
The is a European bowed stringed instrument used in the medieval period, similar to a modern violin but with a somewhat longer and deeper body, three to five gut strings, and a leaf-shaped pegbox with frontal tuning pegs, sometimes with a figure-8 shaped body. Whatever external form they had, the box-soundchest consisted of back and belly joined by ribs, which experience has shown to be the construction for bowed instruments. The most common shape given to the earliest vielles in France was an oval, which with its modifications remained in favour until the Italian lira da braccio asserted itself as the better type, leading to the violin. The instrument was also known as a ''fidel'' or a ''viuola'', although the French name for the instrument, ''Vièle'', is generally used; the word comes from the same root as ''fiddle''. It was one of the most popular instruments of the medieval period, and was used by troubadours and jongleurs from the 13th through the 15th centuries. The ...

Trompe-l'œil
; ; ) is an artistic term for the highly realistic optical illusion of three-dimensional space and objects on a Two-dimensional space, two-dimensional surface. , which is most often associated with painting, tricks the viewer into perceiving painted objects or spaces as real. Forced perspective is a related illusion in architecture. History in painting The phrase, which can also be spelled without the hyphen and Typographic ligature, ligature in English as ''trompe l'oeil'', originates with the artist Louis-Léopold Boilly, who used it as the title of a painting he exhibited in the Paris Salon of 1800. Although the term gained currency only in the early 19th century, the illusionistic technique associated with dates much further back. It was (and is) often employed in murals. Instances from Greek and Roman times are known, for instance in Pompeii. A typical mural might depict a window, door, or hallway, intended to suggest a larger room.

Bow (music)
In music, a bow () is a tensioned stick which has hair (usually horse-tail hair) coated in rosin (to facilitate friction) affixed to it. It is moved across some part (generally some type of strings) of a musical instrument to cause vibration, which the instrument emits as sound. The vast majority of bows are used with string instruments, such as the violin, viola, cello, and bass, although some bows are used with musical saws and other bowed idiophones. Materials and manufacture A bow consists of a specially shaped stick with other material forming a ribbon stretched between its ends, which is used to stroke the string and create sound. Different musical cultures have adopted various designs for the bow. For instance, in some bows a single cord is stretched between the ends of the stick. In the Western tradition of bow making—bows for the instruments of the violin and viol families—a hank of horsehair is normally employed. The manufacture of bows is considered a demandi ...

String (music)
In music, strings are long flexible structures on string instruments that produce sound through vibration. Strings are held under tension so that they can vibrate freely. The pitch (frequency) at which a string will vibrate is primarily related to its vibrating length (also called speaking length), its tension, and its mass per unit of length. A vibrating string produces very little sound by itself. Therefore, most string instruments have a soundboard to amplify the sound. There are two main kinds of strings; plain and wound. "Plain" strings are simply one piece of long cylindrical material, commonly consisted of nylon or gut. "Wound" strings have a central core, with other material being tightly wound around the string . Prior to World War II, strings of many instruments (including violins and guitars) were composed of a material known as catgut, a type of cord made from refined natural fibers of animal intestines. During the mid-twentieth century however, steel and nylo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drone (sound)
In music, a drone is a harmonic or monophonic effect or accompaniment where a note or chord is continuously sounded throughout most or all of a piece. A drone may also be any part of a musical instrument used to produce this effect; an archaic term for this is ''burden'' (''bourdon'' or ''burdon'') such as a "drone ipeof a bagpipe", the pedal point in an organ, or the lowest course of a lute. Α ''burden'' is also part of a song that is repeated at the end of each stanza, such as the chorus or refrain.Brabner, John H F., ed. (1884). The national encyclopædia', Vol. V, p.99. Libr. ed. William McKenzie. . Musical effect "Of all harmonic devices, it droneis not only the simplest, but probably also the most fertile." A drone effect can be achieved through a sustained sound or through repetition of a note. It most often establishes a tonality upon which the rest of the piece is built. A drone can be instrumental, vocal or both. Drone (both instrumental and vocal) can be placed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lira Da Braccio
The lira da braccio (or ''lira de braccio'' or ''lyra de bracio''Michael Praetorius. Syntagma Musicum Theatrum Instrumentorum seu Sciagraphia Wolfenbüttel 1620) was a European Bow (music), bowed string instrument of the Renaissance music, Renaissance. It was used by Italy, Italian poet-musicians in noble court, court in the 15th and 16th centuries to accompany their improvisation, improvised recitations of lyric poetry, lyric and narrative poetry.Howard Mayer Brown and Sterling Scott Jones. "Lira da braccio", ''Grove Dictionary of Music and Musicians, Grove Music Online'', ed. L. Macy (accessed November 11, 2006)grovemusic.com (subscription access) It is most closely related to the medieval fiddle, or vielle, and like the vielle had a leaf-shaped pegbox with frontal pegs. Fiddles with Drone (sound), drone strings are seen beginning in the 9th century (Byzantine lyra), and the instrument continued to develop through the 16th century.

Musical Instrument
A musical instrument is a device created or adapted to make Music, musical sounds. In principle, any object that produces sound can be considered a musical instrument—it is through purpose that the object becomes a musical instrument. A person who plays a musical instrument is known as an ''#Instrumentalist, instrumentalist''. The history of musical instruments dates to the beginnings of human culture. Early musical instruments may have been used for rituals, such as a horn (music), horn to signal success on the hunt, or a drum in a religious ceremony. Cultures eventually developed composition and performance of melody, melodies for entertainment. Musical instruments evolved in step with changing applications and technologies. The exact date and specific origin of the first device considered a musical instrument, is widely disputed. The oldest object identified by scholars as a musical instrument, is Divje Babe flute, a simple flute, dated back 50,000–60,000 years. Many scho ...

Angel
An angel is a spiritual (without a physical body), heavenly, or supernatural being, usually humanoid with bird-like wings, often depicted as a messenger or intermediary between God (the transcendent) and humanity (the profane) in various traditions like the Abrahamic religions. Other roles include protectors and guides for humans, such as guardian angels and servants of God. In Western belief-systems the term is often used to distinguish benevolent from malevolent intermediary beings. Emphasizing the distance between God and mankind, revelation-based belief-systems require angels to bridge the gap between the earthly and the transcendent realm. Angels play a lesser role in monistic belief-systems, since the gap is non-existent. However, angelic beings might be conceived as aid to achieve a proper relationship with the divine. Abrahamic religions describe angelic hierarchies, which vary by religion and sect. Some angels have specific names (such as Gabriel or Mich ...

Wing
A wing is a type of fin that produces both Lift (force), lift and drag while moving through air. Wings are defined by two shape characteristics, an airfoil section and a planform (aeronautics), planform. Wing efficiency is expressed as lift-to-drag ratio, which compares the benefit of lift with the air resistance of a given wing shape, as it flies. Aerodynamics is the study of wing performance in air. Equivalent Foil (fluid mechanics), foils that move through water are found on Hydrofoil, hydrofoil power vessels and Sailing hydrofoil, foiling sailboats that lift out of the water at speed and on submarines that use diving planes to point the boat upwards or downwards, while running submerged. Hydrodynamics is the study of foil performance in water. Etymology and usage The word "wing" from the Old Norse ''vængr'' for many centuries referred mainly to the foremost limb (anatomy), limbs of birds (in addition to the architectural aisle). But in recent centuries the word's meaning ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foot
The foot (: feet) is an anatomical structure found in many vertebrates. It is the terminal portion of a limb which bears weight and allows locomotion. In many animals with feet, the foot is an organ at the terminal part of the leg made up of one or more segments or bones, generally including claws and/or nails. Etymology The word "foot", in the sense of meaning the "terminal part of the leg of a vertebrate animal" comes from Old English ''fot'', from Proto-Germanic *''fot'' (source also of Old Frisian ''fot'', Old Saxon ''fot'', Old Norse ''fotr'', Danish ''fod'', Swedish ''fot'', Dutch ''voet'', Old High German ''fuoz'', German ''Fuß'', Gothic ''fotus'', all meaning "foot"), from PIE root *''ped-'' "foot". The plural form ''feet'' is an instance of i-mutation. Structure The human foot is a strong and complex mechanical structure containing 26 bones, 33 joints (20 of which are actively articulated), and more than a hundred muscles, tendons, and ligaments.Podiatry Chan ...

Human Leg
The leg is the entire lower limb (anatomy), limb of the human body, including the foot, thigh or sometimes even the hip or Gluteal muscles, buttock region. The major bones of the leg are the femur (thigh bone), tibia (shin bone), and adjacent fibula. There are 30 bones in each leg. The thigh is located in between the hip and knee. The calf (leg), calf (rear) and Tibia#Structure, shin (front), or shank, are located between the knee and ankle. Legs are used for standing, many forms of human movement, recreation such as dancing, and constitute a significant portion of a person's mass. Evolution has led to the human leg's development into a mechanism specifically adapted for efficient bipedalism, bipedal gait. While the capacity to walk upright is not unique to humans, other primates can only achieve this for short periods and at a great expenditure of energy. In humans, female legs generally have greater hip anteversion and tibiofemoral angles, while male legs have longer femur a ...
