Sorry I don't have time for the rest but here is the first question.
Explanation:
Classical musicians perform, compose and/or conduct music. They might play an instrument or sing live or recorded classical music, do session work for backing tracks, adverts and film.
A studio musician is in essence a musical “gun for hire,” a musician who is paid to play on tracks or even in live performances without actually being a member of the band. The studio musician career basically emerged in the 1920s and 1930s as the infant recording industry began to grow's, conduct performances, or write music.
