Singing is the act of producing
musical sounds with the
voice, and augments regular
speech by the use of both
tonality and
rhythm. One who sings is called a
singer or
vocalist. Singers perform
music known as
songs that can be sung either with or without
accompaniment by
musical instruments. Singing is often done in a group of other musicians, such as in a
choir of singers with different voice ranges, or in an ensemble with instrumentalists, such as a
rock group or
baroque ensemble. As in many respects human song is a form of sustained
speech, nearly anyone able to speak can also sing. Singing can be formal or informal, arranged or improvised. It may be done for pleasure, comfort, ritual, education, or profit. Excellence in singing requires time, dedication, instruction, and regular
practice.
Professional singers usually build their
careers around one specific
musical genre, such as classical or rock. They typically take
voice training provided by voice teachers or
vocal coaches throughout their careers.
