The Job

Essentially, singers are employed to perform music with their voices by using their knowledge of vocal sound and delivery, harmony, melody, and rhythm. They put their individual vocal styles into the songs they sing, and they interpret music accordingly. The inherent sounds of the voices in a performance play a significant part in how a song will affect an audience; this essential aspect of a singer's voice is known as its tone.

Classical singers are usually categorized according to the range and quality of their voices, beginning with the highest singing voice, the soprano, and ending with the lowest, the bass; voices in between include mezzo soprano, contralto, tenor, and baritone. Singers perform either alone (in which case they are referred to as soloists) or as members of an ensemble, or group. They sing by either following a score, which is the printed musical text, or by memorizing the material. Also, they may sing either with or without instrumental accompaniment; singing without accompaniment is called a cappella. In opera—which are plays set to music—singers perform the various roles, much as actors do, interpreting the drama with their voices to the accompaniment of a symphony orchestra.

Classical singers may perform a variety of musical styles, or specialize in a specific period; they may give recitals, or perform as members of an ensemble. Classical singers generally undergo years of voice training and instruction in musical theory. They develop their vocal technique and learn how to project without harming their voices. Classical singers rarely use a microphone when they sing; nonetheless, their voices must be heard above the orchestra. Because classical singers often perform music from many different languages, they learn how to pronounce these languages, and often how to speak them as well. Those who are involved in opera work for opera companies in major cities throughout the country and often travel extensively. Some classical singers also perform in other musical areas.

Professional singers tend to perform in a chosen style of music, such as jazz, rock, or blues, among many others. Many singers pursue careers that will lead them to perform for coveted recording contracts, on concert tours, and for television and motion pictures. Others perform in rock, pop, country, gospel, or folk groups, singing in concert halls, nightclubs, and churches and at social gatherings and for small studio recordings. Whereas virtuosos, classical artists who are expertly skilled in their singing style, tend to perform traditional pieces that have been handed down through hundreds of years, singers in other areas often perform popular, current pieces, and often songs that they themselves have composed.

Another style of music in which formal training is often helpful is jazz. Jazz singers learn phrasing, breathing, and vocal techniques; often, the goal of a jazz singer is to become as much a part of the instrumentation as the piano, saxophone, trumpet, or trombone. Many jazz singers perform scat singing, in which the voice is used in an improvisational way much like any other instrument.

Folk singers perform songs that may be many years old, or they may write their own songs. Folk singers generally perform songs that express a certain cultural tradition; while some folk singers specialize in their own or another culture, others may sing songs from a great variety of cultural and musical traditions. In the United States, folk singing is particularly linked to the acoustic guitar, and many singers accompany themselves while singing.

A cappella singing, which is singing without musical accompaniment, takes many forms. A cappella music may be a part of classical music; it may also be a part of folk music, as in the singing of barbershop quartets. Another form, called doo-wop, is closely linked to rock and rhythm and blues music.

Gospel music, which evolved in the United States, is a form of sacred music; gospel singers generally sing as part of a choir, accompanied by an organ, or other musical instruments, but may also perform a cappella. Many popular singers began their careers as singers in church and gospel choirs before entering jazz, pop, blues, or rock.

Pop/rock singers generally require no formal training whatsoever. Rock music is a very broad term encompassing many different styles of music, such as heavy metal, punk, rap, rhythm and blues, rockabilly, techno, and many others. Many popular rock singers cannot even sing. But rock singers learn to express themselves and their music, developing their own phrasing and vocal techniques. Rock singers usually sing as part of a band, or with a backing band to accompany them. Rock singers usually sing with microphones so that they can be heard above the amplified instruments around them.

All singers practice and rehearse their songs and music. Some singers read from music scores while performing; others perform from memory. Yet all must gain an intimate knowledge of their music, so that they can best convey its meanings and feelings to their audience. Singers must also exercise their voices even when not performing. Some singers perform as featured soloists and artists. Others perform as part of a choir or as backup singers adding harmony to the lead singer's voice.
