Sonata, musical composition for one or more instruments. In the classical sense, the term refers to a work for piano solo or for a string or spiritual instrument with a piano, consisting of several independent parts. The plan of the composite multi-part sonata and the restriction in the use of the term to only solo works were formed in the second half of the 18th century.
The word “sonata” is often also used in the term “sonata form”: in this case it refers not to a multi-part work, but to the formal structure of one part of the sonata. The sonata form is also found in symphonies, concerts, trios, quartets, quintets, even in overtures, etc.

Most pianos range from 86 semitones from a subcontract to a octave to 5 octaves (older instruments may be limited to a note of 4 octaves above; you can even find instruments with a wider range).
In the neutral position, the strings, in addition to the last one and a half to two octaves, are in contact with the dampers. When you press the keys, a device of levers, straps and hammers is called a piano mechanic. After pressing, the damper is separated from the corresponding choir of strings so that the string can sound freely, and a hammer studded with a fillet (felt) hits it. Continue reading
