Double Whole Note - Breve Rest

A related symbol is the double whole rest (or breve rest), which usually denotes a silence for the same duration (Read 1969, 93). Double whole rests are drawn as filled-in rectangles occupying the whole vertical space between the second and third lines from the top of the musical staff. They are often used in long silent passages which are not divided into separate bars to indicate a rest of two bars (Read 1969, 101). This and longer rests are collectively known as multiple rests (Read 1969, 99).
