Final answer:
The celesta is described as having a bell-like timbre and is classified as an idiophone, not a woodwind, string, or voice-like instrument.
Step-by-step explanation:
The celesta is best described as having a bell-like timbre. It is neither a woodwind instrument, a small cello, nor an instrument that mimics the human voice. Instead, the celesta is a keyboard instrument where hammers strike metal plates or bars, giving it a unique and magical bell-like sound, often used to add a sparkling texture to orchestral pieces. Due to its distinctive ethereal tone, one of the most famous examples of its use is in Tchaikovsky's "Dance of the Sugar Plum Fairy" from The Nutcracker. The celesta belongs to the idiophones category as defined by the common classification system in ethnomusicology, because it produces sound primarily by the instrument's body vibrating without the use of strings or membranes.
