Everything about Barline totally explained
In
musical notation, a
bar or
measure is a segment of time defined as a given number of
beats of a given duration. The word
measure is heard more frequently in the
U.S., while
bar is used in other English-speaking countries, although musicians generally understand both usages. The word
bar derives from the vertical lines which separate one measure from another, and not the bar-like (for example, rectangular) dimensions of a typical measure of music.
A
bar line (or
barline) is a vertical line which separates bars. A
double bar can consist of two single barlines drawn close together, separating two
sections within a piece, or a barline followed by a thicker barline, indicating the end of a piece or movement. A
repeat barline looks like the second type of double barline but it has two dots, one above the other, indicating that the section of music that's before is to be repeated. The beginning of the repeated passage can be marked by a
begin-repeat barline; if this is absent the repeat is understood to be from the beginning of the piece or movement. This begin-repeat barline, if appearing at the beginning of a staff, doesn't act as a true barline because no bar is before it; its only function is to indicate the beginning of the passage to be repeated.
Note that the term
double bar refers not to a type of
bar (for example, measure), but to a type of
barline.
Music end is a term for the barline denoting the end of a piece of music.
In music with a regular
meter, bars function to indicate a periodic
agogic accent in the music. Traditionally the first beat of each bar is slightly accented, regardless of its duration. In music employing
mixed meters, barlines are instead used to indicate the beginning of rhythmic note groups, but this is subject to wide variation: some composers use dashed barlines, others (including
Hugo Distler) have placed barlines at different places in the different parts to indicate varied groupings from part to part.
A
hypermeasure, large-scale or high-level measure, or measure-group is a
metric unit in which, generally, each regular measure is one beat (actually
hyperbeat) of a larger meter. Thus a beat is to a measure as a measure/hyperbeat is to a hypermeasure. Hypermeasures must be larger than a notated bar, perceived as a unit, consist of a pattern of strong and weak beats, and along with adjacent hypermeasures, which must be of the same length, create a sense of
hypermeter. The term was coined by
Edward T. Cone.
History
Barlines came into general use in the 1600s, when music began to be written in
score format rather than individual parts. 16th-century usage was primarily restricted to
lute and
vihuela music, but such barlines typically were not used to indicate a regular meter.
