What are the different ranges of men's singing voices and how do they differ from each other?

Men's singing voices are typically categorized into four main ranges: bass, baritone, tenor, and countertenor. These ranges differ based on the pitch and timbre of the voice. Bass voices are the lowest, with a rich and deep tone, while baritones have a slightly higher range with a warm and full sound. Tenors have a higher pitch and are known for their clarity and agility in the upper register. Countertenors are the highest male voice type, often possessing a falsetto or head voice quality. Each range has its own unique characteristics and is suited for different types of music and vocal styles.
