Sound generation

The Celesta action

Schiedmayer is today worldwide the only manufacturer of the Celesta as invented and patented by Victor Mustel.

Only Schiedmayer uses the Celesta action developed by Victor Mustel and specified in his patent:

  • The felt hammer is set in motion by pressing the key.
  • The felt hammer strikes the steel sound plate from above.
  • The sound plate is placed above a wooden resonator.

It is this unique action mechanism that generates the typical, overtone-rich Celesta sound.

There are keyboard glockenspiels made by other manufacturers using a piano action (sound plates are struck vertically/from the side) or a grand-piano action (sound plates are struck from below). So it is very misleading to call these instruments a celesta which unfortunately happens.

Due to the construction, instruments with piano-/grand-piano action do not create the typical and unique Celesta sound according to the specifications of the inventor Victor Mustel.

Schiedmayer does use a full-size grand-piano keyboard but not a grand-piano action.

Resonators

Made from specially seasoned beechwood, the resonators are the main sound carriers in the celesta, and responsible for the remarkable staying power of the sound.

Sound Plates

The steel sound plates are worked to precise standards in order to produce the inimitable Celesta sound of our instruments.

Our instruments are tuned to a standard pitch of 442 Hz unless otherwise required.
