How does the fugue work? A musical subject begins the piece. After stating its opening theme, a second line of music enters, answering the subject by imitating the same theme at a different pitch level. The fugue can contain any number of independent lines of music, imitating the main subject and all working together musically. Between entries of the subject in the composition, you may hear musical “episodes” that elaborate the main theme and add interest for the listener.
For a visual representation of the fugue, go here to check out Bach’s Little Fugue in G minor. This great video visually shows each individual line of music. The subject begins in the green line followed by an answer in orange. You can then watch as the pink and purple lines of music enter at different pitches and while independent, work together as a team to create a beautiful piece of music.
What is an example of a fugue within Bach’s musical output? The Well-Tempered Clavier is a famous work that consists of two books that each contain twenty-four fugues matched with a prelude that take the keyboardist through every major and minor key.
