Singers work a variety of hours but usually includes a lot of weekends and nights. They also spend numerous hours rehearsing and usually only have intermittent work. Most work part-time and have other jobs to compensate times that are not getting paid to sing. It can take many years to get signed on by an agent or recording studio therefore it can be very competitive in nature. 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.
