Which instrument has the lowest range limit of F3?

The vibraphone is the correct choice because it typically has a range that starts from F3 and extends up to D8. This range allows the vibraphone to occupy a unique middle-register voice among mallet instruments, with F3 being the lowest note produced on a standard vibraphone. The instrument is known for its resonant bars and characteristic sustained sound created by motor-driven resonators, allowing it to stand out in orchestral and contemporary music settings.

In contrast, the marimba has a lower range than the vibraphone, usually beginning around C2, making it unsuitable for this question. The celeste, often used for its ethereal sound, typically starts around middle C (C4), while the harmonium has a different function and range entirely, focusing more on a drone or accompaniment style rather than a melodic low range. Thus, the vibraphone is correctly identified as the instrument with F3 as its lowest pitch limit.
