Individuals aiming to become professional musicians, singers, composers, songwriters, music teachers and practitioners of other music-related professions such as music history professors, sound engineers, and so on study in specialized post-secondary programs offered by colleges, universities and music conservatories. Some institutions that train individuals for careers in music offer training in a wide range of professions, as is the case with many of the top U.S. universities, which offer degrees in music performance (including singing and playing instruments), music history, music theory, music composition, music education (for individuals aiming to become elementary or high school music teachers) and, in some cases, conducting. On the other hand, some small colleges may only offer training in a single profession (e.g., sound recording).
