How does piano work?

The modern piano contains two rows of 88 black and white keys. It's used as basis for numbering pitches, beinning with A0( A Zero) and B0( B Zero), followed by 7 octaves from C1( C One) to C8(C Eight), totally 8 octaves. There are52 white keys of instruments make up the seven notes of the C major scale. There are 36 shorter black key with locted above white keys. Music sheet use bass clef to notate pitches in low to middle ranges, the treble clef to notate pitches in middle to high ranges.

As example of upright piano, three separate assemblies of 100 differents parts are involved in getting the force of the pianist's finger from the key to string. three assembly: key assembly, wippen assembly and hammer assembly.

The key is basically a straight piece of wood that strikes the wippen assembly. The complex wippen assembly transfers the key's force to the hammer, throwing it toward the string.

On the end of strings is supported on bridges, which are attached to the strings are transmitted to the soundboard through the bridges and loud sounds resonates as a result of the soundboard vibrating the air. The entire piano, notably the soundboard, vibrates to produce sounds.
