* Sound production: A harpsichord produces sound when a quill plucks a string.
* Action: The action of a harpsichord is relatively simple, consisting of a key that, when depressed, causes a quill to pluck a string.
* Timbre: The sound of a harpsichord is bright and crisp, with a relatively short decay.
Piano
* Sound production: A piano produces sound when a hammer strikes a string.
* Action: The action of a piano is more complex than that of a harpsichord, involving a series of levers and hammers that allow for a wide range of dynamics.
* Timbre: The sound of a piano is richer and more mellow than that of a harpsichord, with a longer decay.
Electric piano
* Sound production: An electric piano produces sound by amplifying the vibrations of a metal tine or bar.
* Action: The action of an electric piano is similar to that of a piano, but it uses electrical signals to amplify the sound rather than hammers.
* Timbre: The sound of an electric piano can vary greatly depending on the type of instrument, but it is typically bright and percussive.
