Final answer:
In music, 'range' primarily refers to the span from the lowest to the highest note a singer or instrument can produce, whereas technically, dynamic range might also relate to contrasts in loudness in performance.
Step-by-step explanation:
The term 'range' in music can refer to different concepts. The first meaning of range is the highest and lowest notes an instrument or a singer can play or sing. For example, a soprano singer may have a range from middle C (C4) to high C (C6), showcasing the vocal capabilities of that individual from the lowest to highest note they can produce.
The second meaning of range involves the dynamic range in a musical performance, which refers to the contrast between the softest and loudest sounds a performer or a group of performers can produce. Dynamic range is important in conveying emotion and adding expressiveness to a performance. While not one of the options provided in the specific question, this definition complements the earlier meaning and is relevant in the broader musical context.
