What instrument has a range that extends from C3 to C7?

The celeste is known for its unique tonal qualities and specific pitch range, which indeed extends from C3 to C7. This instrument, often used in orchestral settings and for special effects, produces a soft, ethereal sound due to its mechanism, which typically consists of metal plates struck by hammers. The extended range facilitates the performance of a wide variety of melodies and harmonies, allowing musicians to create delicate textures in their compositions.

In contrast, the harmonium generally has a more limited range, often extending only up to around G6 for typical models. The piano covers a much broader range, spanning from A0 to C8, making it one of the most versatile instruments in terms of pitch. The organ also has a wide range similar to the piano, but it can vary based on the type of organ; some models can extend as low as C1. Thus, while each of these instruments is valuable in its own right, the celeste uniquely fits the specified range of C3 to C7.
