In music, a
note head is the elliptical part of a
note. Note heads may be coloured completely black or white, indicating the
note value (i.e., rhythmic duration). In a
whole note, the note head is the only component of the note. Shorter note values attach a
stem to the note head, and possibly
beams or flags. The longer
double whole note can be written with vertical lines surrounding it, two attached note heads, or a rectangular note head.
