Many musicians specialize in a particular genre. They may also sing. Singers interpret music using their knowledge of voice production, melody and harmony. They may sing solo or with a group. Composers write and edit their own scores, often with the aid of a computer.
Arrangers adapt musical compositions to a particular style or group.
Conductors select musicians, choose music, and direct rehearsals and performances. Extensive and prolonged training, often beginning at a very early age, is necessary to acquire the skill, knowledge and ability to conduct. If you have the talent, versatility, poise and stage presence to pursue a musical career, be prepared for intermittent employment and lots of practice sessions. Musicians usually practice and perform at night or on weekends, often in cities away from home. Most work full-time jobs in other occupations.
