      Music Theory

      Why do the opening notes of Beethoven's famous "Symphony No. 5" sound strong and driving rather than leisurely and soothing? The answer can be found by turning to music theory, the study of the concepts and compositional methods involved in the creation of music. Music theory examines musical qualities such as timbre, tone, pitch, and texture, as well as compositional elements such as rhythm, dynamics, tempo, and much more. And do you have perfect pitch like Mozart? If you do you can usually hear a melody, then sit at the piano and tickle the ivories or strum the strings of a guitar and play it by ear. A song—or any piece of music—is made up of two or more parts, or sections, which together create the whole of the composition. A ritornello, for instance, is a melodic sequence that “returns” multiple times throughout the composition. Harmony, the musical scale, how chords are formed, and the musical notation necessary to allow other musicians to play a piece of music are all parts of the musical education you’ll need to be a pro in the field.
