[custom_adv] A singer is someone who 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. [custom_adv] 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, and the sinuses. [custom_adv] 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. [custom_adv] A singer is an artist or performer who crafts a vocal song using various techniques and training. Singers often practice daily and will hire professional voice coaches to help them hone their craft. Singers may write their own music or sing music written by others. In addition to singing, singers may work as music teachers or voice coaches. [custom_adv] Professional singers have typically had a lot of training, are highly talented, and have an excellent ear for identifying tone and pitch. They also possess a certain level of natural singing ability including a wide vocal range or pleasant vocal resonation. Singers often freelance and are contracted on a per job basis, either as a singer or as a consultant or judge in singing competitions. [custom_adv] Singers have distinct personalities. They tend to be artistic individuals, which means they’re creative, intuitive, sensitive, articulate, and expressive. They are unstructured, original, nonconforming, and innovative. Some of them are also enterprising, meaning they’re adventurous, ambitious, assertive, extroverted, energetic, enthusiastic, confident, and optimistic. [custom_adv] Theatrical singers are live performers who often perform nightly performances at a theatre. Opera singers are a specialization of theatrical singers that typically perform in a home theatre they are employed by. A theatrical singer in a main role will usually have their own dressing room and voice coach. Supporting or back-up singers will often share a common dressing area and receive less perks than a singer in a main role. [custom_adv] Professional recording singers exist outside of the entertainment industry in small numbers and are typically employed in marketing sectors for use in marketing jingles and advertisements. These singers will usually work as collaborators and writers of the pieces they sing and will work out of an office.
