The difference in pitch between two sounds.

A progression of events suggesting narrative cohesion, especially one that rises to a climax and settles to a final conclusion.

A space between objects, points, or units, especially when making uniform amounts of separation

To form an arc.

An amount of time between events, especially of uniform duration separating events in a series

To move or seem to move in a curved path

A segment of an athletic workout in which an athlete runs, swims, or does other exercise over a series of predetermined distances at regular time increments with intermittent rests.

(astronomy) That part of a circle which a heavenly body appears to pass through as it moves above and below the horizon.

A set of numbers consisting of all the numbers between a pair of given numbers along with either, both, or none of the endpoints.

(geometry) A continuous part of the circumference of a circle (circular arc) or of another curve.

A closed interval.

A curve, in general. Category:en:Curves

An open interval.

A band contained within parallel curves, or something of that shape.

A half-open interval.

(electrics) A flow of current across an insulating medium; especially a hot, luminous discharge between either two electrodes or as lightning.

A line segment representing the set of numbers in an interval.

A story arc.

Chiefly British An intermission, as between acts of a play.

(mathematics) A continuous mapping from a real interval (typically [0, 1]) into a space.

(Music) The difference, usually expressed in the number of steps, between two pitches.

(graph theory) A directed edge.

A distance in space.

The three-point line.

A period of time.

(film) An arclight.

(music) The difference (a ratio or logarithmic measure) in pitch between two notes, often referring to those two pitches themselves (otherwise known as a dyad).

(ambitransitive) To move following a curved path.

(mathematics) A connected section of the real line which may be empty or have a length of zero.

(transitive) To shape into an arc; to hold in the form of an arc.

An intermission.

(intransitive) To form an electrical arc.

(sports) half time, a scheduled intermission between the periods of play

A portion of a curved line; as, the arc of a circle or of an ellipse.
