Whole note rest may also be used in music of free rhythm, such as Anglican chant, to denote a whole measure. A whole note (American) or semibreve (British) is a musical note represented by a hollow oval note head—like a half note (or "minim")—and no note stem (see Figure 1). Its length is equal to four beats in time, that is the whole measure (or bar). Most other notes are fractions of the whole note. Half notes last for one half the duration of the whole note, quarter notes (or "crotchets") last for one quarter the duration, and a double whole note
