Varieties of the instrument itself is not so much a piano and a piano. The difference between them lies only in the size and position of strings, what size and subject: at the piano – horizontal, and piano – vertical. In General, the design of the piano, in addition to the keys, includes strings and mallets, so it partially can be put in the category of stringed and percussion. Also the instrument has pedals, clicking on which you can make the sound longer or more weak-sounding.
The piano is also fairly bulky design. The total tension of all the strings in the instrument up to eight tons. Also the tool is quite expensive.

The heaviest thousand ever written for the piano works is the third Concerto of Rachmaninoff with the orchestra.

Piano can be used as a solo instrument, and playing with the orchestra. Learning to play an instrument takes 5 to 7 years, and it's pretty difficult, but enjoyable process, which may participate everyone.
