Double whole note

Left: breve in modern notation. Centre: breve in mensural notation used in some modern scores as the first form.

In music, a double whole note (American), breve (British) or double note lasts two times as long as a whole note (or semibreve). It is the second-longest note value still in use in modern music notation. The next longest notated note is the longa, which is double the length of the breve. The longest notated note (though now obsolete except in some contexts) is the maxima.
