Old Navy is a brand of clothing and chain of stores that is owned by Gap Inc., which also owns the Gap, Banana Republic, and Forth & Towne brands. Old Navy's corporate operations are with The Gap in San Francisco and San Bruno, California.
Launched in 1994 as a value chain, Old Navy opened its first store Colma, California. As of 2005, Old Navy has more than 800 stores in many cities in the United States and Canada, the largest of which is in Chicago, Illinois.
The name "Old Navy" was chosen because originally the stores were supposed to emulate the look and feel of a traditional military surplus store. While this motif was quickly dropped, many stores retain a warehouse-like/urban decor.
The online store, oldnavy.com, commenced operations in 2000.
In 2001, Old Navy opened 12 stores in Canada, offerring the same products at slightly higher prices.
Old Navy's target market largely consists of teenagers; accordingly, the clothing is trendy, yet more affordable than its other Gap Inc. counterparts. (And rivals like American Eagle, Abercrombie and Fitch and Hollister) Old Navy's stores contain specialized sections for infants, boys, girls, men, and women, and within these categories contain styles for many occasions. In addition to clothing, Old Navy also sells a variety of accessories such as shoes, handbags, toys, hats, and sunglasses. Perhaps Old Navy's most recognizable product are their popular flip-flops.
Old Navy informally bills itself as an all-American brand. The chain releases a shirt every summer emblazoned with an American flag. Each year's shirt features a slightly-altered flag graphic with the year listed below. In its Canadian stores, a similar shirt with the Canadian flag is sold.
The most notable aspect of Old Navy's television advertisements are their satirical tone toward a retro time period, vaguely between 1940 and 1960. In sharp contrast to the Gap's advertisements, Old Navy's feature chipper family members sporting their clothing line while engaging in wholesome family activities, such as barbecueing. A common tagline used in their campaigns is the widely recognized "(insert clothing article here) for the whole family!".
Old Navy is also known for its advertising campaigns featuring celebrities such as Morgan Fairchild and hip hop artist Lil Kim. Another popular spokesperson was former Vogue editor Carrie Donovan, who often appeared in ads with company "spokesdog", Magic. According to Gap Inc., Magic, a Airedale terrier mix, was rescued from the streets of San Jose. Magic remains an informal mascot of the company, though Donovan has since passed away.
Jeffersons stars Isabel Sanford and Sherman Helmsley appeared in a number of Old Navy television commercials in the late 1990s and early 2000s.

Jeffersons stars Isabel Sanford and Sherman Helmsley appeared in a number of Old Navy television commercials in the late 1990s and early 2000s. See also: Social history of the piano. Magic remains an informal mascot of the company, though Donovan has since passed away. Hence pianos have gained a place in the popular consciousness, and are sometimes referred to by nicknames, including: "the ivories", "the joanna", "the eighty-eight", and "the black(s) and white(s)." Playing the piano is sometimes referred to as "tickling the ivories". According to Gap Inc., Magic, a Airedale terrier mix, was rescued from the streets of San Jose. Pianos were, and are, extremely popular instruments for private household ownership, especially among the middle- and upper-classes. Another popular spokesperson was former Vogue editor Carrie Donovan, who often appeared in ads with company "spokesdog", Magic. A large number of composers being proficient pianists, the piano is often used as a tool for composition.
Old Navy is also known for its advertising campaigns featuring celebrities such as Morgan Fairchild and hip hop artist Lil Kim. The piano is a crucial instrument in Western classical music, jazz, film, television and electronic game music, and most other complex western musical genres. A common tagline used in their campaigns is the widely recognized "(insert clothing article here) for the whole family!". Top-quality but aged pianos can be restored or reconditioned, by replacing a great number of their parts to produce an instrument closely similar to a new one. In sharp contrast to the Gap's advertisements, Old Navy's feature chipper family members sporting their clothing line while engaging in wholesome family activities, such as barbecueing. The hammers of pianos are voiced to compensate for gradual hardening. The most notable aspect of Old Navy's television advertisements are their satirical tone toward a retro time period, vaguely between 1940 and 1960. Pianos are regularly tuned to keep them up to pitch and produce a pleasing sound; by convention they are tuned to the internationally recognised standard concert pitch of A = 440 Hz.
In its Canadian stores, a similar shirt with the Canadian flag is sold. The largest piano built, the Fazioli F308, weighs 691 kg (1520 lb). Each year's shirt features a slightly-altered flag graphic with the year listed below. The requirement of structural strength, fulfilled with stout hardwood and thick metal, makes a piano heavy; even a small upright can weigh 136 kg (300 lb), and the Steinway concert grand (Model D) weighs 480 kg (990 lb). The chain releases a shirt every summer emblazoned with an American flag. At one time the Yamaha firm innovated a plastic called "Ivorine" or "Ivorite", since imitated by other makers, that mimics the look and feel of ivory. Old Navy informally bills itself as an all-American brand. Legal ivory can still be obtained in limited quantities.
Perhaps Old Navy's most recognizable product are their popular flip-flops. Traditionally, the black keys were made from ebony and the white keys were covered with strips of ivory, but since ivory-yielding species are now endangered and protected by treaty, plastics are now almost exclusively used. In addition to clothing, Old Navy also sells a variety of accessories such as shoes, handbags, toys, hats, and sunglasses. Spruce is normally used in high-quality pianos. (And rivals like American Eagle, Abercrombie and Fitch and Hollister) Old Navy's stores contain specialized sections for infants, boys, girls, men, and women, and within these categories contain styles for many occasions. Piano keys are generally made of spruce or basswood, for lightness. counterparts. In cheap pianos, the soundboard is often made of plywood.
Old Navy's target market largely consists of teenagers; accordingly, the clothing is trendy, yet more affordable than its other Gap Inc. The best piano makers use close-grained, quarter-sawn, defect-free spruce, and make sure that it has been carefully dried over a long period of time before making it into soundboards. In 2001, Old Navy opened 12 stores in Canada, offerring the same products at slightly higher prices. Spruce is chosen for its high ratio of strength to weight. The online store, oldnavy.com, commenced operations in 2000. In quality pianos this is made of solid spruce (that is, spruce boards glued together at their edges). While this motif was quickly dropped, many stores retain a warehouse-like/urban decor. The part of the piano where materials probably matter more than anywhere else is the soundboard.
The name "Old Navy" was chosen because originally the stores were supposed to emulate the look and feel of a traditional military surplus store. More recently, the Kawai firm has built pianos with action parts made of more modern and effective plastics such as carbon fiber; these parts have held up better and have generally received the respect of piano technicians. As of 2005, Old Navy has more than 800 stores in many cities in the United States and Canada, the largest of which is in Chicago, Illinois. The Steinway firm once incorporated Teflon, a synthetic material developed by DuPont, for some grand action parts in place of cloth, but ultimately abandoned the experiment due to an inherent "clicking" which invariably developed over time. Launched in 1994 as a value chain, Old Navy opened its first store Colma, California. Early plastics were incorporated into some pianos in the late 1940s and 1950s, but proved disastrous because they crystallized and lost their strength after only a few decades of use. . Since World War II, plastics have become available.

The numerous grand parts and upright parts of a piano action are generally hardwood (e.g. Piano makers overcome this handicap by polishing, painting, and decorating the plate; often plates include the manufacturer's ornamental medallion and can be strikingly attractive.
The inclusion in a piano of an extremely large piece of metal is potentially an aesthetic handicap. The casting of the plate is a delicate art, since the dimensions are crucial and the iron shrinks by about one percent during cooling. Some manufacturers now use cast steel in their plates, for greater strength. Since the strings are attached to the plate at one end, any vibrations transmitted to the plate will result in loss of energy to the desired (efficient) channel of sound transmission, namely the bridge and the soundboard.
It is advantageous for the plate to be quite massive. The plate, or metal frame, of a piano is usually made of cast iron. For the acoustic reasons behind this, see Piano acoustics. The bass strings of a piano are made of a steel core wrapped with copper wire, to increase their flexibility.
They are manufactured to vary as little as possible in diameter, since all deviations from uniformity introduce tonal distortion. Piano strings (also called piano wire), which must endure years of extreme tension and hard blows, are made of high quality steel. It is made of hardwood, and generally is laminated (built of multiple layers) for additional strength and gripping power. The pinblock, which holds the tuning pins in place, is another area of the piano where toughness is important.
The thick wooden braces at the bottom (grands) or back (uprights) of the piano are not as acoustically important as the rim, and are often made of a softwood, even in top-quality pianos, in order to save weight. Conklin, the purpose of a sturdy rim is so that "the vibrational energy will stay as much as possible in the soundboard instead of dissipating uselessly in the case parts, which are inefficient radiators of sound." The rim is normally made by laminating flexible strips of hardwood to the desired shape, a system that was developed by Theodore Steinway in 1880. According to Harold A. In quality pianos, the outer rim of the piano is made of a hardwood, normally maple or beech.
Many parts of a piano are made of materials selected for extreme sturdiness. The entire action of the piano is thus shifted to allow the pianist to play music written in one key so that it sounds in a different key. The rare transposing piano, of which Irving Berlin possessed an example, uses the middle pedal as a clutch which disengages the keyboard from the mechanism, enabling the keyboard to be moved to left or right with a lever. It works like the damper pedal, but only lifts the dampers for the lowest notes.
Other uprights have a bass sustain as a middle pedal. The practice pedal is rarely used in performance. This pedal, which can usually be locked in place by depressing it and pushing it to one side, drops a strip of felt between the hammers and the keys so that all the notes are greatly muted — a handy feature for those wish to practice in domestic surroundings without disturbing the neighbours. Some upright pianos have a practice pedal in place of the sostenuto.
(Almost all modern grand pianos have a sostenuto pedal, while most upright pianos do not.) A number of twentieth-century works specifically call for the use of this pedal, for example Olivier Messiaen's Catalogue d'oiseaux. The sostenuto pedal was the last of the three pedals to be added to the standard piano, and to this day many pianos are not equipped with a sostenuto pedal. This can be useful for musical passages with pedal points and other otherwise tricky or impossible situations. This makes it possible to sustain some notes (by depressing the sostenuto pedal before notes to be sustained are released) while the player's hands are free to play other notes.
The sostenuto pedal or "middle pedal" keeps raised any damper that was raised at the moment the pedal is depressed. increase the already-great versatility of such instruments. Pitch bends, leslie speaker on/off, vibrato modulation, etc. Digital pianos often use this pedal to alter the sound to that of another instrument such as the organ, guitar, or harmonica.
Since the hammers have less distance to travel this reduces the speed at which they hit the strings, and hence the volume is reduced, but this does not change tone quality in the way the "una corda" pedal does on a grand piano. On upright pianos, the soft pedal operates a mechanism which moves the hammers' resting position closer to the strings. In modern pianos, the strings are spaced too closely to permit a true "una corda" effect — if shifted far enough to strike just one string on one note, the hammers would also hit the string of the next note. In the 18th and early 19th centuries, the soft pedal was more effective than today, since it was possible at that time to use it to strike three, two or even just one string per note—this is the origin of the name "una corda", Italian for "one string".
The soft pedal was invented by Cristofori and thus appeared on the very earliest pianos. For notation of the soft pedal in printed music, see Italian musical terms. This softens the note and also modifies its tone quality. On a grand piano, this pedal shifts the whole action including the keyboard slightly to the left, so that hammers that normally strike all three of the strings for a note strike only two of them.
The soft pedal or "una corda" pedal is placed leftmost in the row of pedals. In contrast, the sustaining pedal was used only sparingly by the composers of the 18th century, including Haydn, Mozart and in early works by Beethoven; in that era, pedalling was considered primarily as a special coloristic effect. Sensitive pedaling is one of the techniques a pianist must master, since piano music from Chopin onwards tends to benefit from extensive use of the sustaining pedal, both as a means of achieving a singing tone and as an aid to legato. Secondly, raising the damper pedal causes all the strings to vibrate sympathetically with whichever notes are being played, which greatly enriches the piano's tone.
First, it assists the pianist in producing a legato (playing smoothly connected notes) in passages where no fingering is available to make this otherwise possible. This serves two purposes. When the damper pedal is pressed, all the dampers on the piano are lifted at once, so that every string can vibrate. The damper is raised off the string whenever the key for that note is pressed.
Every string on the piano, except the top two octaves, is equipped with a damper, which is a padded device that prevents the string from vibrating. It is placed as the rightmost pedal in the group. The damper pedal (also called the sustaining pedal or loud pedal) is often simply called "the pedal," since it is the most frequently used. (In the 18th century, some pianos used levers pressed upward by the player's knee instead of pedals.) The three pedals that have become more or less standard on the modern piano are the following.
Pianos have had pedals, or some close equivalent, since the earliest days. The extra keys are the same as the other keys in appearance. On their instruments, the range is extended both down the bass to F0 and up the treble to F8 for a full eight octaves. More recently, the Stuart and Sons company has also manufactured extended-range pianos.
Only a very small number of works composed for piano actually use these notes. The extra keys are added primarily for increased resonance; that is, they vibrate sympathetically with other strings whenever the damper pedal is depressed and thus give a fuller tone. Sometimes, these extra keys are hidden under a small hinged lid, which can be flipped down to cover the keys and avoid visual disorientation in a pianist unfamiliar with the extended keyboard; on others, the colours of the extra white keys are reversed (black instead of white). The most notable example of an extended range can be found on Bösendorfer pianos, two models which extend the normal range downwards to F0, with one other model going as far as a bottom C0, making a full eight octave range.
Many older pianos only have 85 keys (seven octaves from A0 to A7), while some manufacturers extend the range further in one or both directions. Almost every modern piano has 88 keys (seven octaves plus a minor third, from A0 to C8). This arrangement was inherited from the harpsichord without change, with the trivial exception of the colour scheme (white for notes in the C major scale and black for other notes) which became standard for pianos in the late 18th century. For the arrangement of the keys on a piano keyboard, see Musical keyboard.
Progress is being made in this area by including physical models of sympathetic vibration in the synthesis software. Since this sympathetic vibration is considered central to a beautiful piano tone, in many experts' estimation digital pianos still do not compete with the best acoustic pianos in tone quality. However, with current technology, it remains difficult to duplicate a crucial aspect of acoustic pianos, namely that when the damper pedal (see below) is depressed, the strings not struck vibrate sympathetically when other strings are struck. The best digital pianos are sophisticated, with features including working pedals, weighted keys, multiple voices, MIDI interfaces.
Since the 1980s, digital pianos have been available, which use digital sampling technology to reproduce the sound of each piano note. A relatively recent development is the prepared piano, which is simply a standard grand piano which has had objects placed inside it before a performance in order to alter its sound, or which has had its mechanism changed in some way. Also in the 19th century, toy pianos began to be manufactured. In 1863, Henri Fourneaux invented the player piano, a kind of piano which "plays itself" from a piano roll without the need for a pianist.
For recent advances, see Innovations in the piano. It is considered harder to produce a sensitive piano action when the hammers move horizontally, rather than upward against gravity as in a grand piano; however, the very best upright pianos now approach the level of grand pianos of the same size in tone quality and responsiveness. Upright pianos, also called vertical pianos, are more compact because the frame and strings are placed vertically, extending in both directions from the keyboard and hammers. All else being equal, longer pianos have better sound and lower inharmonicity of the strings (so that the strings can be tuned closer to equal temperament in relation to the standard pitch with less stretching), so that full-size grands are almost always used for public concerts, whereas baby grands are often chosen for domestic use where space and cost are considerations.
Manufacturers and models vary, but a rough generalisation distinguishes the "concert grand", (between about 2.2 m to 3 m long) from the "boudoir grand" (about 1.7 m to 2.2 m) and the smaller "baby grand" (which may be shorter than it is wide). There are several sizes of grand piano. This makes the grand piano a large instrument, for which the ideal setting is a spacious room with high ceilings for proper resonance. Grand pianos have the frame and strings placed horizontally, with the strings extending away from the keyboard.
Modern pianos come in two basic configurations and several sizes: the grand piano and the upright piano. Finally, participants in the authentic performance movement have constructed new copies of the old instruments and used them in performance; this has provided important new insights and interpretations of the music. A few pianists simply ignore this problem; others modify their playing style to help compensate for the difference in instruments, for example by using less pedal. These sound rather blurred on a modern piano if played as written, but which sound fine when played on restorations or replicas of the pianos of Beethoven's day.
53). For example, Beethoven sometimes wrote long passages in which he directs the player to keep the damper pedal down throughout (a famous example occurs in the last movement of the "Waldstein" sonata, Op. Others have noted that the music itself often seems to require the resources of the early piano. This view is perhaps more plausible in the case of Beethoven, who composed at the beginning of the era of piano growth, than it is in the case of Haydn or Mozart.
One view that is sometimes taken is that these composers were dissatisfied with their pianos, and in fact were writing visionary "music of the future" with a more robust sound in mind. Even the music of the early Romantics, such as Chopin and Schumann, was written for pianos substantially different from ours. The problem is that much of the most widely admired piano repertoire — for example, that of Haydn, Mozart, and Beethoven — was composed for a type of instrument that is rather different from the modern instruments on which this music is normally performed today. The huge changes in the evolution of the piano have somewhat vexing consequences for musical performance.
These were uncommon. The giraffe piano, by contrast, was mechanically like a grand piano, but the strings ran vertically up from the keyboard rather than horizontally away from it, making it a very tall instrument. Most had a wood frame, though later designs incorporated increasing amounts of iron. Square pianos were produced through the early 20th century; the tone they produced is widely considered to be inferior.
It was similar to the upright piano in its mechanism. The once-popular square piano was an inexpensive design that had the strings and frame on a horizontal plane, but running across the length of the keyboard rather than away from it. Some early pianos had shapes and designs that are no longer in use. For some recent developments, see Innovations in the piano.
The modern concert grand achieved essentially its present form around the beginning of the 20th century, and progress since then has been only incremental. Some other important technical innovations of this era include the following:. As revised by Henri Herz about 1840, the double escapement action ultimately became the standard action for grand pianos, used by all manufacturers. In 1821, Sébastien Érard invented the double escapement action, which permitted a note to be repeated even if the key had not yet risen to its maximum vertical position, a great benefit for rapid playing.
By the 1820s, the centre of innovation had shifted to Paris, where the Érard firm manufactured pianos used by Chopin and Liszt. The two schools, however, used different piano actions: the Broadwood one more robust, the Viennese more sensitive. The Viennese makers followed these trends. The Broadwood firm, which sent pianos to both Haydn and Beethoven, was the first to build pianos with a range of more than five octaves: five octaves and a fifth during the 1790s, six octaves by 1810 (in time for Beethoven to use the extra notes in his later works), and seven octaves by 1820.
Over time, the Broadwood instruments grew progressively larger, louder, and more robustly constructed. In the first part of this era, technological progress owed much to the English firm of Broadwood, which already had a strong reputation for the splendour and powerful tone of its harpsichords. The tonal range of the piano was also increased, from the five octaves of Mozart's day to the 7 1/3 (or even more) octaves found on modern pianos. Over time, piano playing became a more strenuous and muscle-taxing activity, as the force needed to depress the keys, as well as the length of key travel, was increased.
It was also a response to the ongoing Industrial Revolution, which made available technological resources like high-quality steel for strings (see piano wire) and precision casting for the production of iron frames. This evolution was in response to a consistent preference by composers and pianists for a more powerful, sustained piano sound. In the lengthy period lasting from about 1790 to 1890, the Mozart-era piano underwent tremendous changes which led to the modern form of the instrument. The term fortepiano is nowadays often used to distinguish the 18th-century style of instrument from later pianos.
The piano of Mozart's day had a softer, clearer tone than today's pianos, with less sustaining power. It was for such instruments that Mozart composed his concertos and sonatas, and replicas of them are built today for use in authentic-instrument performance. The Viennese-style pianos were built with wooden frames, two strings per note, and had leather-covered hammers. Piano-making flourished during the late 18th century in the work of the Viennese school, which included Johann Andreas Stein (who worked in Augsburg, Germany) and the Viennese makers Nannette Stein (daughter of Johann Andreas) and Anton Walter.
Bach did approve of a later instrument he saw in 1747, and apparently even served as an agent to help sell Silbermann's pianos. Though this earned him some animosity from Silbermann, the latter did apparently heed the criticism. Bach did not like it at that time, claiming that the higher notes were too soft to allow a full dynamic range. Silbermann showed Bach one of his early instruments in the 1730s.
Virtually all subsequent pianos incorporated some version of Silbermann's idea. Silbermann's pianos were virtually direct copies of Cristofori's, but with an important addition: Silbermann invented the forerunner of the modern damper pedal (also known as the sustaining pedal or loud pedal), which lifts all the dampers from the strings at once. One of these builders was Gottfried Silbermann, better known as an organ builder. This article was widely distributed, and most of the next generation of piano builders started their work as a result of reading it.
Cristofori's new instrument remained relatively unknown until an Italian writer, Scipione Maffei, wrote an enthusiastic article about it (1711), including a diagram of the mechanism. However, in comparison with the clavichord (the only previous keyboard instrument capable of dynamic nuance) they were considerably louder, and had more sustaining power. Cristofori's early instruments were made with thin strings and were much quieter than the modern piano. Cristofori's piano action served as a model for the many different approaches to piano actions that were to follow.
Moreover, the hammers must return to their rest position without bouncing violently, and it must be possible to repeat a note rapidly. Cristofori's great success was to solve, without any prior example, the fundamental mechanical problem of piano design: the hammers must strike the string but not continue to touch it once they have struck (which would damp the sound). Cristofori, himself a harpsichord maker, was well acquainted with this body of knowledge. In particular, it benefited from centuries of work on the harpsichord, which had shown the most effective ways to construct the case, the soundboard, the bridge, and the keyboard.
Like many other inventions, the pianoforte was founded on earlier technological innovations. Cristofori built only about twenty pianofortes before he died in 1731; the three that survive today date from the 1720s. When he built this instrument is not entirely clear, but an inventory made by Cristofori's employers, the Medici family, indicates the existence of an early Cristofori instrument by the year 1700. He called it a gravicembalo col piano e forte.
Bartolomeo Cristofori of Florence, Italy, invented the first pianoforte. . In a piano, the strings are struck by hammers which immediately rebound, leaving the string to vibrate freely. In the clavichord, strings are struck by tangents which remain in contact with the string.
In a harpsichord, strings are plucked by quills or similar material. The three instruments differ in the mechanism of sound production. As a keyboard stringed instrument, the piano is similar to the clavichord and harpsichord. Literally harpsichord with soft and loud, this refers to the ability of the piano to produce notes at different volumes depending on how hard its keys are pressed.
It is derived from the original Italian name for the instrument, clavicembalo col piano e forte. The word piano is a shortened form of the word "pianoforte", which is seldom used except in formal language. These vibrations are transmitted though the bridges to the soundboard. The piano produces sound by striking steel strings with felt hammers.

The Piano Book by Larry Fine (4th ed. In the 1988 edition, the primary article can be found in "Musical Instruments". The Encyclopædia Britannica (available online by subscription) also includes a great deal of information about the piano. Main article: "Pianoforte".
The authoritative New Grove Dictionary of Music and Musicians (available online by subscription), contains a wealth of information on the piano. Similar systems developed by Blüthner (1873), as well as Taskin (1788), and Collard (1821) used more distinctly ringing undamped vibrations to modify tone. In 1872 Theodore Steinway patented a system to control different components of string vibrations by tuning their secondary parts in octave relationships with the sounding lengths. duplexes or aliquot scales.
in 1859. Overstringing was invented by Jean-Henri Pape during the 1820s, and first patented for use in grand pianos in the United States by Henry Steinway Jr. This permits larger, but not necessarily longer, strings to fit within the case of the piano. The strings are placed in a vertically overlapping slanted arrangement, with two heights of bridges on the soundboard, rather than just one.
the overstrung scale, also called "cross-stringing". the sostenuto pedal (see below), invented in 1844 by Jean Louis Boisselot and improved by the Steinway firm in 1874. Hammers covered with compressed felt were introduced by the Parisian maker Jean-Henri Pape in 1826, and are now universally used. The harder, tauter steel strings required a softer hammer type to maintain good tone quality.
felt hammers. Babcock later worked for the Chickering & Mackays firm, where the first iron frame in grand pianos (1843) was developed. The single piece cast iron frame was patented in 1825 in Boston by Alpheus Babcock, culminating an earlier trend to use ever more iron parts to reinforce the piano. The iron frame was the ultimate solution to the problem of structural integrity as the strings were gradually made thicker, tenser, and more numerous (in a modern grand the total string tension can approach 20 tons).
The iron frame, also called the "plate", sits atop the soundboard, and serves as the primary bulwark against the force of string tension. the iron frame. use of three strings rather than two for all but the lower notes.
