Tonal range refers to the spectrum of pitches that a voice or instrument can produce. It is typically measured from the lowest note to the highest note that can be comfortably played or sung. For example, a soprano singer has a higher tonal range compared to a bass singer, who can produce deeper notes. In music, understanding tonal range is essential for composers and performers. It helps in selecting appropriate pieces that suit a musician's capabilities, ensuring that the music is both enjoyable and technically feasible. Instruments like the piano or guitar also have specific tonal ranges that define their unique sound.
