Musical composition, conducting, and performance are all carried out by musicians. Musician, according to the United States Employment Service, is a generic word used to describe someone who is involved in the field of music as a professional endeavour. Performers who perform for an audience include songwriters who compose music as well as write lyrics for songs, conductors who lead a musical performance, and composers who create music and lyrics for songs. The majority of the time, a music performer is either a vocalist who sings or an instrumentalist who plays a musical instrument. Whether performing alone or as a member of a band, orchestra or ensemble of musicians, musicians may make a living. The majority of musicians specialise in a particular musical style, although other artists perform in a number of various genres based on their cultural and historical background. A recording artist is a musician who creates, records, and distributes musical works.
