It was for such instruments that Wolfgang Amadeus Mozart composed his concertos and sonatas, and replicas of them are built in the 21st century for use in authentic-instrument performance of his music. The pianos of Mozart's day had a softer, more ethereal tone than 21st century pianos or English pianos, with less sustaining power. The term ""fortepiano"" now distinguishes these early instruments (and modern re-creations) from later pianos. In the period from about 1790 to"

Most modern pianos have a row of 88 black and white keys, 52 white keys for the notes of the C major scale (C, D, E, F, G, A and B) and 36 shorter black keys, which are raised above the white keys, and set further back on the keyboard. This means that the piano can play 88 different pitches (or ""notes""), going from the deepest bass range to the highest treble. The black keys are for the ""accidentals"" (F/G, G/A, A/B, C/D, and"

Almost every modern piano has 36 black keys and 52 white keys for a total of 88 keys (seven octaves plus a minor third, from A0 to C8). Most makers standardized around the 88 key format during the 1880s and 1890s time period.

When a key is pressed, the action which results in the striking and dampening of the piano wires, results from a mechanism which contrasts to any existing piano made today: a long thin but sturdy metal rod which reaches halfway down the back of the instrument is lifted. This lifting motion causes the piano wires to be struck and then dampened when the key is released as is typical of a traditional piano, at least on those notes which require dampening (on a minipiano, the highest 13 notes are not dampened). There are 73 keys"
"since ivory-yielding species are now endangered and protected by treaty, or are illegal in some countries, makers use plastics almost exclusively. Also, ivory tends to chip more easily than plastic. Legal ivory can still be obtained in limited quantities. The Yamaha firm invented a plastic called ""Ivorite"" that they claim mimics the look and feel of ivory. It has since been imitated by other makers. Almost every modern piano has 52 white keys and 36 black keys for a total of 88 keys (seven octaves plus a minor third, from A to C).

Similarly, the pitch to which they are tuned is rarely close to the standard of 440 Hz for the A above middle C. A typical toy piano will have a range of one to three octaves. The cheapest models may not have black keys, or the black keys may be painted on. This means they can play a fixed diatonic scale (or an approximately tuned version of it), but not the full chromatic scale, or diatonic scales in other keys. Typically,"
"diatonic toy pianos have only eight keys and can play one octave. Other variants may have non-functioning black keys between every key (which would make it appear to play the quarter tones between E/F and B/C), but they either do not play, play the same notes as an adjacent white key, or play a special sound effect. Early toy pianos used glass bars to produce their sound, but Albert Schoenhut, son of a German toy-making family, introduced metal sounding bars to make the instrument more durable.

In modern times they are also made of fibreglass or plastics. When struck they produce a bright clicking noise. Claves are sometimes hollow and carved in the middle to amplify the sound. Many examples of clave-like instruments can be found around the world. The basic principle when playing claves is to allow at least one of them to resonate. The usual technique is to hold one lightly with the thumb"

Modern piano keyboards ordinarily have an octave span of 164–165 mm; resulting in the width of black keys averaging 13.7 mm and white keys about 23.5 mm wide at the base, disregarding space between keys. Several reduced-size standards have been proposed and marketed. A 15/16 size (152 mm octave span) and the 7/8 DS Standard (140 mm octave span) keyboard developed by Christopher Donison in the 1970s and developed and marketed by Steinbuhler & Company.

The Bösendorfer sound is usually described as darker or richer than the purer but less full-bodied sound of other pianos, such as Steinway & Sons or Yamaha. On the Imperial Grand, this characteristic tonal quality in part derives from the inclusion of"
"Split sharp A split sharp is a kind of key found in some early keyboard instruments, such as the harpsichord, clavichord, or organ. It is a musical key divided in two, with separately depressible front and back sections, each sounding its own pitch. The particular keys that were split were those that play the sharps and flats on the standard musical keyboard (the ""black keys"" on a modern piano). Split sharps served two distinct purposes. First, in the broken octave, they allowed an instrument to include deep bass notes while retaining a short, compact keyboard. Second, in older music, tuning"

The earliest designs of keyboards were based heavily on the notes used in Gregorian chant (the seven diatonic notes plus B-flat) and as such would often include B and B both as diatonic ""white notes,"" with the B at the leftmost side of the keyboard and the B at the rightmost. Thus, an octave would have ""eight"" ""white keys"" and only four ""black keys."" The emphasis on these eight notes would continue for"

"Piano wire Piano wire, or ""music wire"", is a specialized type of wire made to become springs or (as the name implies) to be used as piano strings. It is made from tempered high-carbon steel, also known as spring steel, which replaced iron as the material starting in 1834. Piano wire has a very high tensile strength to cope with the heavy demands placed upon piano strings; accordingly, piano wire is also used for a number of other purposes, including springs, surgical uses, and in special effects. The oldest record of wire being made for musical instruments is from Augsburg"

To these may be added the seventh diatonic scale, with a diminished fifth above the reference note, the Locrian scale. These could be transposed not only to include one flat in the signature (as described by Glarean), but to all twelve notes of the chromatic scale, resulting in a total of eighty-four diatonic scales. The modern musical keyboard originated as a diatonic keyboard with only white keys. The black keys were progressively added for several purposes:"

Although this key was relatively unexplored during the Baroque and Classical periods, Franz Schubert used it quite frequently in his sets of écossaises, valses and so on, as well as entering it and even flatter keys in his sonatas, impromptus and the like.

D-flat major was used as the key for the slow movements of Joseph Haydn's Piano Sonata Hob XVI:46 in A-flat major, and Beethoven's ""Appassionata Sonata"".

This cylindrical bore differs from the saxophone's conical one and gives the clarinet its characteristic tone, causing it to overblow at the twelfth compared with the saxophone's octave.
