Musicians play one or more instruments. To make themselves more marketable, many musicians become proficient in multiple musical instruments or styles.
Musicians play in bands, orchestras, or small groups. Those in bands may play at weddings, private parties, clubs, or bars while they try to build enough fans to get a recording contract or representation by an agent. Some musicians work as a part of a large group of musicians who must work and practice together, such as an orchestra. A few musicians become section leaders, who may be responsible for assigning parts to other musicians or leading rehearsals.
