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
Note value Any flags always go to the right of the stem. A note value may be augmented by adding a dot after it. This dot adds the next briefer note value, making it one and a half times its original duration. A number of dots ("n") lengthen the note value by its value, so two dots add two lower note values, making a total of one and three quarters times its original duration. The rare three dots make it one and seven eighths the duration, and so on. The double dot was first used in 1752 by J.J. Quantz; in music
