Editing Sixty-fourth note

{{short description|Musical note duration}}
In [[music notation]], a '''sixty-fourth note''' (North American), or '''hemidemisemiquaver''' or '''semidemisemiquaver''' (British), sometimes called a '''half-thirty-second note''',{{sfn|Burrowes|1874|loc=42}} is a [[Musical note|note]] played for half the duration of a [[thirty-second note]] (or demisemiquaver), hence the name. It first occurs in the late 17th century and, apart from rare occurrences of [[hundred twenty-eighth note]]s (semihemidemisemiquavers) and [[two hundred fifty-sixth note]]s (demisemihemidemisemiquavers), it is the shortest value found in musical notation.{{sfn|Morehen|2001}}

Sixty-fourth notes are notated with a filled-in oval [[notehead]] and a straight [[note stem]] with four flags. The stem is drawn to the left of the notehead going downward when the note is above or on the middle line of the [[musical staff|staff]]. When the notehead is below the middle line the stem is drawn to the right of the notehead going upward. A single 64th note is always stemmed with flags, while two or more are usually [[beam (music)|beamed]] in groups.{{sfn|Gerou and Lusk|1996|p=211}}

A similar, but rarely encountered symbol is the '''sixty-fourth [[rest (music)|rest]]''' (or '''hemidemisemiquaver rest''', shown in figure 1) which denotes silence for the same duration as a sixty-fourth note.

Notes shorter than a sixty-fourth note are very rarely used, though the [[hundred twenty-eighth note]]—otherwise known as the ''semihemidemisemiquaver''{{sfn|Haas|2011|loc=112}}—and even shorter notes, are occasionally found.
