<bot>: The major difference between the sound waves of a soprano and a bass singer is the frequency. Sopranos tend to produce higher-pitched notes with higher frequency sound waves, while bass singers tend to produce lower-pitched notes with lower frequency sound waves. Additionally, the amplitude of sound waves produced by bass singers are typically louder than that of sopranos.
