Music is a universal form of self-expression. Musicians and singers convey a culture’s musical traditions and create new forms as well. An ear or talent for music often shows up early in life. While vocal training for singers usually begins in later teen years when the voice matures, musicians can start learning an instrument even sooner. For those who specialize in classical or jazz music, it’s typical to take formal instruction, such as studying with a “master” or earning a bachelor’s or master’s degree in music. Many musicians working in popular music genres, like hip hop, rock, and folk, are self-taught. Musicians and singers need a great deal of skill, tenacity, and sometimes luck to earn a living from music. While they may find work through competitive auditions, most need to promote themselves to find consistent work.
