Different Parts of The Piano


Great piano manufacturers go to enormous lengths to produce a quality instrument that will ensure many years of enjoyment throughout the life of the piano.

The Back:
 The back of a vertical piano, or the bottom in the case of a grand, is the piano's foundation, and must be strong and stable.

The Soundboard:
 The soundboard is the heart of the piano that converts the vibrations of the strings into the tone of the piano. Its purpose is to convert the vibrations of the strings into sound.

 Spruce is the wood of choice that top quality pianos manufactures use for their soundboards. Pianos of lesser quality might use plywood for the soundboard.

Bass and Treble Bridges:
Complete accuracy of the bass and treble bridges is vital for the transfer of the string vibrations to the soundboard (resulting in the fine tonal quality from the lowest bass string to the highest treble).

The Pin Block:
The pin block runs the width of the piano and is attached to the back of the piano. The tuning pins keep the piano in tune by maintaining the correct string tension. Defective pin blocks can be replaced on grand pianos but it is nearly impossible to replace a vertical piano's pin block. Loose pins are usually the result of excessive dryness over a period of time. The single most important thing is that the pin block is properly designed and the holes are drilled accurately.

 Hard rock maple is the material of choice in high quality pianos.

The Piano Plate:
  The piano plate is made of cast iron and is attached to the back frame must resist tons of string tension.

Pedals:
Most pianos have three pedals... some with just two pedals are usually made overseas.
  • The left pedal when depressed, shifts the action slightly to on one restricting the hammers to only strike two strings not the usual three strings. This makes the piano sound softer.
  • The right pedal is called the damper and when depressed lifts the damper off of the string allowing the string to sound until the pedal is released.
  • The middle pedal on some pianos maintains the bass. On others, it maintains a single note or individual chord.
