How the piano makes its sound

In the Hornbostel–Sachs system, which classifies instruments by how they produce sound, the piano belongs to the board zithers: strings are stretched across a flat board or box – the family of the piano, harpsichord and hammered dulcimer.

More broadly it is one of the chordophones (string instruments), where sound comes from vibrating strings, amplified by a resonating body.

Its timbre – the colour that lets you tell it apart from other instruments playing the same note – comes from the mix of overtones its body and resonator emphasise.

Range of the piano

The typical range of the piano runs from A0 (27.5 Hz) to C8 (4,186 Hz) – about 7.2 octaves. Harmonics extend its sound far higher.

From Wikipedia

A piano is a keyboard instrument that produces sound when its keys are pressed, activating an action mechanism where hammers strike strings. Modern pianos have a row of 88 black and white keys—with the exception of the Bosendörfer and Stuart & Sons pianos—and tuned to a chromatic scale in equal temperament. A musician who specializes in piano is called a pianist.

There are two main types of piano: the grand piano and the upright piano. The grand piano offers better sound and more precise key control, making it the preferred choice when space and budget allow. The grand piano is also considered a necessity in venues hosting skilled pianists. The upright piano is more commonly used because of its smaller size and lower cost.
