The history of singing goes back to the earliest recordings of mankind (as early as 800 B.C.) and songs are believed to have been used even before the development of modern languages. In western culture, singers were often restricted to only singing in churches until the fourteenth century. The rise of operas and performances thereafter laid the groundwork for today's professional singers.

A singer (also referred to as a vocalist) is a person that vocalizes musical sounds with tone and pitch, and uses his or her own voice to produce music. Singers may sing solo or in a group, and are oftentimes accompanied by instrumental music. Professional singers are usually highly trained and also possess a certain level of natural singing ability including a wide vocal range or pleasant vocal resonation. Singing is an accepted art form that is taught in most public and private schools. It can also be a fun activity and be casual entertainment, such as karaoke.

The physical act of singing occurs as air passes through the larynx, throat, and mouth, and it's interesting to note that vocal resonation in singing involves seven areas of the human body:

• Chest
• Tracheal tree
• Larynx
• Pharynx
• Oral Cavity
• Nasal Cavity
• Sinuses
