Definition
A barline is a symbol in notation to separate bars. This symbol is usually a simple vertical line on the staff.
Other types of barlines include:
- Barlines between staves in a staff-system (to avoid visually impairing the flow of music, especially suited for transciptions of polyphonic mensurally notated music)
- Ticks, small lines on top of a staff, usually running at a certain metronome speed, an invention of Luciano Berio in his Sequenza I for solo flute (1958).
