Singing is producing sounds with the voice. It adds more to regular speech with rhythm.
Ranges of singing
A soprano is a rather high range of singing. They can usually sing a lot higher than middle C. An alto is a middle ranged singer. They can usually go a little lower than middle C but also a little bit higher. A tenor is a rather low range of singing. Most tenor singers don't make it much higher than middle C. A bass range of singing is a really low range. Almost all bass singers can not make it to a middle C. All of this information is partly shown in the image above.
