U+1D101 "𝄁" Musical Symbol Double Barline is a member of the Musical Symbols block, used in Western musical notation to indicate a major structural division within a piece of music, typically marking the end of a section or movement. It visually resembles two closely spaced vertical lines drawn through the staff, differing from a final barline by not having a thicker outer line. This symbol is distinct from other barline characters in Unicode, and it is intended for use in digital sheet music and text representations of musical scores, enabling precise typographic rendering of common notational conventions.
