Eighth note

An eighth note (American) or a quaver (British) is a musical note played for one eighth the duration of a whole note (semibreve), hence the name. This amounts to twice the value of the sixteenth note (semiquaver). It is half the duration of a quarter note (crotchet), one quarter the duration of a half note (minim), one eighth the duration of whole note (semibreve), one sixteenth the duration of a double whole note (breve), and one thirty-second the duration of a longa. It is the equivalent of the fusa in mensural notation (Morehen and Rastell 2001).

Eighth notes are notated with an oval, filled-in note head and a straight note stem with one flag note flag (see Figure 1). The stem is placed to the right of the notehead and extends upwards if the notehead lies below the middle line of the staff, and to the left of the notehead extending downwards if the notehead lies on or above the middle line of the staff, in instrumental notation. In vocal music, a middle-line notehead extends upward instead of downward. A related symbol is the eighth rest (or quaver rest), which denotes a silence for the same duration (Anon. 2016).

In Unicode, the symbols U+266A (♪) and U+266B (♫) are an eighth note and beamed pair of eighth notes respectively. The two symbols are inherited from the early 1980s code page 437, where they occupied codes 13 and 14 respectively. Additions to the Unicode standard also incorporated additional eighth note depictions from Japanese emoji sets: ascending eighth notes (U+1F39C, 🎜), descending eighth notes (U+1F39D, 🎝), a graphical generic musical note generally depicted as an eighth note (U+1F3B5, 🎵), and three unconnected eighth notes in sequence (U+1F3B6, 🎶). Unicode's Musical Symbols block includes several variations of the eighth note; these are the versions intended to be used in computerized musical notation (as opposed to the others, which are graphical dingbats).
