Here's why:
* Pronouns are typically used to refer to people or things. Instruments, while objects, are often seen as having a distinct purpose and agency.
* "It" is often used. While not specific to instruments, "it" is the most common pronoun used for inanimate objects.
* Descriptive phrases are more common. For example, instead of saying "It played the melody beautifully," you might say "The violin played the melody beautifully."
Here are some ways to use pronouns when referring to instruments:
* "It" (general): "I bought a new guitar, and it sounds amazing."
* "It" with clarification: "The piano was tuned perfectly, and it played beautifully."
* Using the instrument's name: "The cello has a rich, warm tone."
* Using a possessive pronoun: "The trumpet's bell is dented."
Ultimately, the best choice depends on the context and how you want to emphasize the instrument.
