How does a celesta produce its sound?

The celesta is a percussion instrument that functions similarly to an upright piano. It produces sound through a keyboard and a simplified piano action, where small felt-covered hammers strike a series of tuned metal bars.1

Because it uses metal bars to create sound, the celesta is classified as a metallophone. To enhance the sound, each metal bar is paired with a wooden box or chamber that is tuned to resonate with and reinforce the bar's fundamental harmonic. The instrument also features a pedal that operates a felt-pad damper system, allowing the player to control whether notes are sustained or short.1

It is important to note that the celesta is sometimes confused with the typophone, an instrument that uses steel tuning forks rather than metal bars to produce a softer tone.1
