성악
Vocal music often has a sequence of sustained pitches that rise and fall, creating a melody, but some vocal styles use less distinct pitches, such as chants or a rhythmic speech-like delivery, such as rapping. As well, there are extended vocal techniques that may be used, such as screaming, growling, throat singing, or yodelling. Vocal music is probably the oldest form of music, since it does not require any instrument besides the human voice. All musical cultures have some form or type of vocal music.
