A sixty-fourth note is a musical note that lasts for one sixty-fourth of a whole note's duration. In standard music notation, it is represented by a filled-in oval note head with a stem and typically four flags. This note is often used in fast passages of music, allowing composers to convey rapid rhythms. In terms of timing, a sixty-fourth note is shorter than a thirty-second note and is often grouped with other notes to create complex rhythms. Musicians may encounter this note in various genres, including classical and contemporary music, where intricate patterns are common.
