A dotted bar line is a vertical line made up of a series of dots instead of a solid line. It is used in musical notation to indicate the end of a section or a repeat of a passage. The dotted bar line helps to mark boundaries within a piece of music, signaling to musicians where to stop, start, or repeat sections. It provides a visual cue for navigating the structure of the composition, making it easier to follow and perform.
