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

After this would come the one thousand twenty-fourth note (eight flags or beams), the two thousand forty-eighth note (nine flags or beams), the four thousand ninety-sixth note (ten flags or beams), and so on indefinitely, with each note half the length of its predecessor. The shortest note value to have ever been used in a published work is the 1024th note (notated incorrectly as a 2048th) in Anthony Philip Heinrich's "Toccata Grande Cromatica" from "The Sylviad", Set 2, written around 1825; 256th notes occur frequently in this piece, and some 512th notes also
