Agraffe
An agraffe is a part used principally on grand piano The piano is a stringed keyboard instrument in which the strings are struck by wooden hammers that are coated with a softer material (modern hammers are covered with dense wool felt; some early pianos used leather). It is played using a keyboa ...s. The agraffe is a guide at the tuning-pin end of the string, screwed into the plate, with holes through which the strings pass. It positions the strings vertically and laterally, determines the string's speaking length, and offers a clean termination from which the string can vibrate. Agraffes are used in the bass, tenor, and lower treble, but commonly give way to a '' capo d'astro'' bar in the upper treble. Agraffes are usually made of solid brass, and come in 1, 2 or 3-string configurations. For American pianos they are available in two sizes (1/4" and 7/32" finely threaded studs). The string holes are typically countersunk to eliminate the likelihood of buzzing, even as the ag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Innovations In The Piano
Piano construction is by now a rather conservative area; most of the technological advances were made by about 1900, and indeed it is possible that some contemporary piano buyers might actually be suspicious of pianos that are made differently from the older kind. Yet piano manufacturers, especially the smaller ones, are still experimenting with ways to build better pianos. In the early 21st century, the obvious way to raise the technological level of any mechanical device is to use digital technology to control it (compare the mid 19th century, where the obvious route was to make some of its parts from steel; e.g. piano strings). Of course, digital technology ''has'' been incorporated into pianos, and this innovation is discussed below. But in a sense, it is a far greater challenge to improve the piano in its own terms, as a mechanical/acoustic device. This challenge pits the modern piano designer against some of the finest engineering minds of the nineteenth century, an era when ...

Piano
The piano is a stringed keyboard instrument in which the strings are struck by wooden hammers that are coated with a softer material (modern hammers are covered with dense wool felt; some early pianos used leather). 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. It was invented in Italy by Bartolomeo Cristofori around the year 1700. Description 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 ''clavicembalo col piano e forte'' (key cimbalom with quiet and loud)Pollens (1995, 238) 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 gr ...

Strings (music)
A string is the vibrating element that produces sound in string instruments such as the guitar, harp, piano (piano wire), and members of the violin family. Strings are lengths of a flexible material that a musical instrument holds under tension so that they can vibrate freely, but controllably. Strings may be "plain", consisting only of a single material, like steel, nylon, or gut, or wound, having a "core" of one material and an overwinding of another. This is to make the string vibrate at the desired pitch, while maintaining a low profile and sufficient flexibility for playability. The invention of wound strings, such as nylon covered in wound metal, was a crucial step in string instrument technology, because a metal-wound string can produce a lower pitch than a catgut string of similar thickness. This enabled stringed instruments to be made with less thick bass strings. On string instruments that the player plucks or bows directly (e.g., double bass), this enabled instru ...

Capodastro
A capo (short for ''capodastro'', ''capo tasto'' or ''capotasto'' , Italian for "head of fretboard") , ''capo'' or ''capodastro''; french: capodastre; german: Kapodaster; pt, capotraste; sh, kapodaster; el, καποτάστο, kapotásto. is a device a musician uses on the neck of a stringed (typically fretted) instrument to transpose and shorten the playable length of the strings—hence raising the pitch. It is a common tool for players of guitars, mandolins, mandolas, banjos, ukuleles and bouzoukis. The word derives from the Italian ''capotasto'', which means the nut of a stringed instrument. The earliest known use of ''capotasto'' is by Giovanni Battista Doni who, in his ''Annotazioni'' of 1640, uses it to describe the nut of a viola da gamba The viol (), viola da gamba (), or informally gamba, is any one of a family of bowed, fretted, and stringed instruments with hollow wooden bodies and pegboxes where the tension on the strings can be increased or decreas ...
