In which pitch range does the C trumpet sound?

The C trumpet has a sound range that is categorized as F#3 to D6. This range corresponds to the written notes for the instrument, which typically transposes down a whole step from the concert pitch. When the player plays a written C, it sounds as a concert C. The significance of this range is that it allows for a variety of musical expressions, from the deep resonant tones of lower notes to the bright and clear higher tones, making the C trumpet versatile in both solo and ensemble settings.

In comparison to the other options, while they may represent ranges of other instruments or musical concepts, they do not accurately reflect the specific pitch range of the C trumpet. This knowledge is essential for understanding the instrument's capabilities and role in different musical contexts.
