Answer:
A. the sound quality of a particular instrument or voice
Explanation:
Timbre is the peculiar characteristic of each sound.
Each sound wave has a characteristic shape, which depends on the material that produced the sound. This is what defines the tone of the sound. Timbre is what differentiates two sounds of the same frequency (same note). For example, the C note played on the guitar sounds very different from the C note played on the keyboard or flute. This means that these instruments have different tones.
