una gran fuga
Categories coda
A fugue opens with one main theme, the subject, which then repeats itself with a variation, each repetition is called a voice; when each voice has entered, the exposition is complete; this is occasionally followed by a connecting passage, or episode, developed from previously heard material; further “entries” of the subject then are heard in related keys. Episodes and entries are usually alternated until the “final entry” of the subject by which point the music has returned to the opening key, or tonic, which is often followed by closing material, the coda.
