Basically, a way of analyzing music.

Specifically, music theory is made up of laws, rules, labels and other insights regarding Western music (particularly its harmonic tendencies), pioneered by a man named Rameau.

Music came first, theory came after.
In Music Theory, Roman numeral labels are given to chords in relation to a melodic key center. IV-V-I is the strongest cadence in Western harmony.

A class that explains the structure of music. You'll learn the difference between an A-sharp and a B-flat. Later you get into the rules of writing counterpoints and four-part harmonies, which are useless unless you write classical music, but are still good to know.

The principles/guidlines of classical, real music. Modern musicians tend to neglect music theory or have little knowledge of it. However, most knowledgeable musicians have a basic idea of theory. (Steve Vai and Yngwie Malmsteen to cite two)
