The Various Components of Your Piano

Know Your Instrument
Each component of the piano has its place in creating harmonious melodies. René Sauriol Technicien & Accordeur de Piano presents this little glossary to help you understand the various components of your stringed instrument.

Soundboard
Wood surface that amplifies the sound and diffuses it into the surrounding space. The size of the soundboard affects its resonance.

Bridges
Bearing surfaces for the strings, the bridges are attached to the soundboard, to which they transmit the string vibrations.

Pin Block
Laminated hardwood plank, firmly fixed to the structure, in which the tuning pegs are seated.

Tuning Peg
Made of nickel, the tuning pegs are driven into the pin block. The flexibility of nickel allows for very accurate adjustment of the strings (fine tuning).

Metal Frame
Structure to hold the pressure exerted by the strings (from 215 to 245 in number). The tension totals over 18 tonnes.

Strings
Metal wires of different sizes and lengths, tailored to the frequency to be produced.

Bare strings
Steel rope strings for mid and treble sounds


Wound strings
Copper wound strings to enlarge the steel string diameter and slow oscillations to produce bass sounds

Keyboard
Set of 88 keys (52 white and 36 black) which, when struck, engage the mechanism.

Pedals

Levers to control sound duration and tone
