How many major parts does a baritone consist of?

A baritone typically consists of three major parts: the chest voice, which produces the lower range; the middle voice, which bridges the gap between the chest and head voice; and the head voice, which covers the higher range. These parts allow baritones to achieve a wide vocal range and dynamic expression. Additionally, a baritone's voice can be categorized into different types, such as lyric, dramatic, or Verdi baritone, further enhancing its versatility.
