Glassharmonica
The glass harmonica, also known as the glass armonica, glass harmonium, bowl organ, hydrocrystalophone, or simply the armonica or harmonica (derived from , ''harmonia'', the Greek word for harmony), is a type of musical instrument that uses a series of glass bowls or goblets graduated in size to produce musical tones by means of friction (instruments of this type are known as friction idiophones). It was invented in 1761 by Benjamin Franklin. Names The name "glass harmonica" (also "glass armonica", "glassharmonica"; ''harmonica de verre'', ''harmonica de Franklin'', ''armonica de verre'', or just ''harmonica'' in French; ''Glasharmonika'' in German; ''harmonica'' in Dutch) refers today to any instrument played by rubbing glass or crystal goblets or bowls. The alternative instrument consisting of a set of wine glasses (usually tuned with water) is generally known in English as "musical glasses" or the "glass harp".

Friction Idiophone
Friction idiophones is designation 13 in the Hornbostel-Sachs system of musical instrument classification. These idiophones produce sound by being rubbed either against each other or by means of a non-sounding object. Instruments of this type are not very common; possibly the best known examples are the musical saw and the nail violin. According to Sachs,Sachs, Curt (1940).

Crystallophone
A crystallophone is a musical instrument that produces sound from glass. One of the best known crystallophones is the glass harmonica, a set of rotating glass bowls which produce eerie, clear tones when rubbed with a wet finger. Musical glasses, the glass harp, were documented in Persia in the 14th century. Apel, Willi (1969). Harvard Dictionary of Music', p.347. Harvard. . The "ethereal" quality of instruments such as the glass harmonica exemplified the '' Empfindsamkeit'' and for a while, "the instrument was extraordinarily popular... utAbout 1830 the instrument fell into oblivion." The glasschord (or glasscord) resembles the celesta (a struck plaque idiophone operated by a keyboard) but uses keyboard-driven hammers to strike glass bars instead of metal bars. The glass marimba is similar to the marimba (a stick percussion instrument with a keyboard layout), but has bars of glass instead of wood. The bars, which the performer strikes with padded sticks, are perched on a gl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galileo
Galileo di Vincenzo Bonaiuti de' Galilei (15 February 1564 – 8 January 1642) was an Italian astronomer, physicist and engineer, sometimes described as a polymath. Commonly referred to as Galileo, his name was pronounced (, ). He was born in the city of Pisa, then part of the Duchy of Florence. Galileo has been called the "father" of observational astronomy, modern physics, the scientific method, and modern science. Galileo studied speed and velocity, gravity and free fall, the principle of relativity, inertia, projectile motion and also worked in applied science and technology, describing the properties of pendulums and " hydrostatic balances". He invented the thermoscope and various military compasses, and used the telescope for scientific observations of celestial objects. His contributions to observational astronomy include telescopic confirmation of the phases of Venus, observation of the four largest satellites of Jupiter, observation of Satu ...

Violin Bow
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 demandin ...

Sympathetic Resonance
Sympathetic resonance or sympathetic vibration is a harmonic phenomenon wherein a passive string or vibratory body responds to external vibrations to which it has a harmonic likeness. The classic example is demonstrated with two similarly-tuned tuning forks. When one fork is struck and held near the other, vibrations are induced in the unstruck fork, even though there is no physical contact between them. In similar fashion, strings will respond to the vibrations of a tuning fork when sufficient harmonic relations exist between them. The effect is most noticeable when the two bodies are tuned in unison or an octave apart (corresponding to the first and second harmonics, integer multiples of the inducing frequency), as there is the greatest similarity in vibrational frequency. Sympathetic resonance is an example of injection locking occurring between coupled oscillators, in this case coupled through vibrating air. In musical instruments, sympathetic resonance can produce both d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Accidental (music)
In music, an accidental is a note of a pitch (or pitch class) that is not a member of the scale or mode indicated by the most recently applied key signature. In musical notation, the sharp (), flat (), and natural () symbols, among others, mark such notes—and those symbols are also called accidentals. In the measure (bar) where it appears, an accidental sign raises or lowers the immediately following note (and any repetition of it in the bar) from its normal pitch, overriding the key signature. A note is usually raised or lowered by a semitone, and there are double sharps or flats, which raise or lower the indicated note by two semitones. Accidentals usually apply to all repetitions within the measure in which they appear, unless canceled by another accidental sign, or tied into the following measure. If a note has an accidental and the note is repeated in a different octave within the same measure the accidental is usually repeated, although this convention is far fr ...

Marianne Davies
Marianne Davies (1743 or 1744 – c. 1818) was an English musician, and the sister of the classical soprano Cecilia Davies. She was a singer who also played flute and harpsichord. In 1762 she became the first person to publicly perform on the glass harmonica (also known as the armonica), an instrument consisting of variously sized and tuned glass bowls that rotate on a common shaft, played by touching the spinning glass with wet fingers. She toured in concerts with her sister, performing in Dublin (1763), London, and on the Continent where the two girls became acquainted with the Mozart family. Beethoven also composed music for the instrument. She corresponded regularly with Benjamin Franklin Benjamin Franklin ( April 17, 1790) was an American polymath who was active as a writer, scientist, inventor An invention is a unique or novel device, method, composition, idea or process.

Cambridge
Cambridge ( ) is a university city and the county town in Cambridgeshire, England. It is located on the River Cam approximately north of London. As of the 2021 United Kingdom census, the population of Cambridge was 145,700. Cambridge became an important trading centre during the Roman and Viking ages, and there is archaeological evidence of settlement in the area as early as the Bronze Age. The first town charters were granted in the 12th century, although modern city status was not officially conferred until 1951. The city is most famous as the home of the University of Cambridge, which was founded in 1209 and consistently ranks among the best universities in the world. The buildings of the university include King's College Chapel, Cavendish Laboratory, and the Cambridge University Library, one of the largest legal deposit libraries in the world. The city's skyline is dominated by several college buildings, along with the spire of the Our Lady and the English Marty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Christoph Willibald Gluck
Christoph Willibald (Ritter von) Gluck (; 2 July 1714 – 15 November 1787) was a composer of Italian and French opera in the early classical period. Born in the Upper Palatinate and raised in Bohemia, both part of the Holy Roman Empire, he gained prominence at the Habsburg court at Vienna. There he brought about the practical reform of opera's dramaturgical practices for which many intellectuals had been campaigning. With a series of radical new works in the 1760s, among them ''Orfeo ed Euridice'' and '' Alceste'', he broke the stranglehold that Metastasian '' opera seria'' had enjoyed for much of the century. Gluck introduced more drama by using orchestral recitative and cutting the usually long da capo aria. His later operas have half the length of a typical baroque opera. Future composers like Mozart, Schubert, Berlioz and Wagner revered Gluck very highly. The strong influence of French opera encouraged Gluck to move to Paris in November 1773.
