Singers read and interpret musical compositions and apply their voice and style to create a song. Singers use one or more vocal ranges, such as alto, baritone, or bass in certain music styles, including folk, rock, country, gospel, jazz, or rap. Those working as singers might find employment as back-up performers for bands, commercial jingle singers, cruise ship singers, nightclub entertainers, or even vocal teachers. Most singers are self-employed or freelance artists who work contractually with recording labels, nightclubs, or concert tour venues. Singers work in recording studios creating albums. Some Singers back themselves up on piano or guitar, whereas some focus more on dancing and performing, and leave the rest to a backing band. Singers need more than a great singing voice and a distinct style to succeed in singing professions. Determination, perseverance, self-discipline, self-confidence, and the ability to face rejection are all traits that singers must develop. Communication and interpersonal skills are also important, as singers work with many different people, including managers, agents, recording label executives, and recording studio personnel.
