Which of the following is true about a harpsichord?

A harpsichord is a keyboard instrument that is true to the following characteristics:

1. It is a string instrument: A harpsichord consists of a series of strings stretched across a soundboard, much like a piano.

2. It produces sound through plucking: Unlike a piano where the strings are struck with hammers, a harpsichord produces sound when the strings are plucked by a mechanism called a "jack."

3. It has a distinctive tone: The harpsichord has a unique, bright, and slightly metallic sound. Each note's volume remains constant, regardless of how hard a key is pressed.

4. It was popular during the Baroque period: The harpsichord reached its peak popularity during the Baroque era (roughly 1600-1750). It was a staple instrument in compositions by famous composers like J.S. Bach and G.F. Handel.

5. It has different registers and stops: A harpsichord usually has multiple sets of strings called "registers." It can be equipped with stops that allow the player to choose different combinations of registers, altering the tone and volume of the instrument.

6. It does not have a sustain pedal: Unlike a piano, a harpsichord does not have a sustain pedal. The notes produced by a harpsichord decay relatively quickly after being played.

In summary, a harpsichord is a string instrument, it plucks the strings to produce sound, has a bright and distinctive tone, was popular during the Baroque period, has different registers and stops, and lacks a sustain pedal.
