Study usually begins at a young age. Starting young also helps develop the muscles necessary to play an instrument and good technical skill. Constant practice and study are needed to maintain the ability to perform at a high quality level. Formal training at established institutions is helpful for entry positions. Many musicians prefer to study at music conservatories.
Most employers require experience and proven proficiency.
Many years of formal and informal study and practice are often required. Symphony orchestras usually require at least three to five years of private study. They may also require knowledge of the symphonic repertoire. During formal auditions, musicians demonstrate their knowledge of the repertoire and their ability to sight-read music. Other employers look for talent and knowledge of styles and theory.
