Brief description of the piano by Kavian Lazar

Piano is an acoustic instrument. Invented by Bartolomeo Christofori in 1700 (exact year unknown) in which strings are struck with a hammer. The instrument is played by a keyboard with the fingers or toes. Sixty presses both keys to hammer the strings and play a melody. The word piano stands for the Italian word forte piano, which the early piano models were known by in 1700. The word piano means Soft and the word forte means loud. The amount of sound produced by this instrument depends on the amount of pressure the pianist’s finger has on the key: the higher the pressure on the key, the higher the hammer pressure and the louder the sound produced.

The piano is opposite the harpsichord, because the volume produced in the harpsichord, unlike the piano, is not variable and the volume produced is limited and constant.

The first forte pianos in the 1700s had a quieter sound and a smaller dynamic range. The acoustic piano usually has a wooden protector around the keyboard and metal strings. Pressing one or more keys on the keyboard causes the hammer to hit the wires. The hammer returns to its original position after hitting the wire. And the wires are still in frequency

 Their resonance vibrates.
