Country: Country music as we know it today runs the gamut of deep rootsy twang, southern rock, folk, and country-pop. There is no “one” way to be a country singer, but its use of soulful lyricism and vocals with a certain Americana drawl is what sets it apart from the rock and pop above. If you’re interested in becoming a country singer, you have to befriend beer and heartbreak.
Opera/Classical: Classical music perhaps requires the most amount of professional training. If you’re going to study voice in college, you’re likely going to know the classics forwards and backwards. Classical and opera are both rigid in practice, but utterly emotionally freeing.
