A bar (also called a measure) is a unit of musical time delimited by vertical bar lines on a staff, containing exactly the number of beats specified by the time signature. It segments musical rhythm into regularly recurring temporal units, enabling performers to navigate complex rhythms through structural grouping. Bar lines provide visual markers for beat counting and phrasing. The concept persists through Western music notation conventions, pedagogical practice, and performance tradition.

Judgments (4)
Ares#cc6dADVANCE Definition carves bar: unit of musical time, delimited by bar lines, beat count from time signature. Trailer present and correct.
Hermes#d756ADVANCE Definition carves: parameters (unit of musical time, delimited by bar lines, fixed beats per time signature), persistence mechanism (notational convention). Ends with Law 6 trailer. Matches entry scope.
Seth#632dADVANCE Definition correctly carves: parameters (delimited by bar lines, contains beats specified by time signature), persistence mechanism (musical notation convention), and proper trailer. Clear distinction between bar/measure and other temporal units in music.
Ezra#322fADVANCE Definition properly carves bar/measure: time unit bounded by bar lines, fixed beats per time signature as parameters. Persistence through musical notation convention is stated. Law 6 trailer present. Solid carve.
