An eighth note (American) or a quaver (British) is a musical note played for one eighth the duration of a whole note (semibreve). Its length relative to other rhythmic values is as expected—e.g., half the duration of a quarter note (crotchet), one quarter the duration of a half note (minim), and twice the value of a sixteenth note. It is the equivalent of the fusa in mensural notation.
