The piano (word which in Italian means "soft", and in this case is apócope the original term, "pianoforte", referring to its soft and strong shades) is a musical instrument classified as a keyboard instrument and strings percutidas by traditional classification system, according to the classification of Hornbostel-Sachs is a cordófono simple. The musician who plays the piano called a pianist. Throughout history there have been different types of pianos, but the most common are the grand piano and the upright piano or wall. The piano tuning is a key factor in the sound of the instrument and is done by changing the tension of the strings so that they vibrate at frequencies suitable. In Western music, the piano can be used for the interpretation soloist, for chamber music for the accompaniment, to help compose and rehearse. The first specific compositions for the instrument arose circa 1732 ; among them are the twelve sonatas for piano by Lodovico Giustini entitled Sonate da cimbalo di piano e forte volgarmente detto di Martelletti. Since then, there have been many composers who have created pieces for piano and in many cases those same composers were pianists. The soundboard, also called cabinet, piano is closed enclosure, which is intended to amplify or modulate the sound. It is a primary part of the piano, as in addition to amplify and modulate sound, is a decisive factor in the timbre of the instrument, being important the quality of wood with which it is made, the number of pieces that is constructed and structure. The quality and homogeneity of the wood that the soundboard is made ​​is paramount. In a modern grand piano, usually usually built in wood spruce and has a thickness of 8 mm, twice that of a pianoforte. The length and thickness decreases proportionally from the low register, longer and thicker strings to the high register, smaller thickness and length. The length of the lower strings proportionally affects the external dimensions of the instrument. Therefore, a greater length of the strings tail implies greater piano, increasing sound quality. The same applies to the height of the box upright piano. Virtually all modern pianos have 88 keys, 36 black and 52 white. The number of keys on keyboards has increased over time. In the eighteenth century the harpsichord had little more than 61 keys (up to five octaves ), while most pianos manufactured since 1870 had 88 keys. Modern pianos have a record of seven octaves and a minor third ; ie, from the -2 to do 7. However, many pianos have seven eighths of a register (85-key); ie, from the -2 to the six and some manufacturers extend their record to any of the two extremes, acute or severe. For example, a piano Bösendorfer 225 has 92 keys and Bösendorfer 290 Imperial has 97. The bodies generally have 61 keys by "manual" (part of the organ played with the hands). The weight of the keyboard is a very important factor piano keyboard. On an acoustic piano (with gum or vertical), the weight of the keyboard is directly related to the mechanism of percussion hammer that strikes the string within the soundboard. In an electronic piano sensation of weight that takes place on an acoustic piano is played by a hammer mechanism underneath each key. A modern piano has three pedals. In the early twentieth century, pianos had only the damper pedal and the pedal una corda. But in earlier times it was very experienced, with records lute, bassoon and others even more extravagant effects, not being uncommon to find old pianos with more than four pedals. Beethoven owned a Erard piano with four pedals, one party, which made a total of five. The configuration at an upright piano is slightly different. The inching pedal is on the left, but in this case differs from the grand piano. When pressed, the mechanism about the hammers to the strings, which, at a shorter distance to strike, lower acceleration by pressing the key, which simply reduces the sound volume. When the pedal damper located in the center, a cloth between the hammers and strings stands, which greatly reduces sound and allows you to play the piano without disturbing others. And finally, the right pedal is the resonance, the only thing that is common to both types of piano. In vertical, it works exactly the same. Thank you for supporting the creative commons movement !!
