Illustration of attack-point rhythm
Rhythm conceived as a precise series of durations and attack
points abstracted from notated values and a metronomic pulse.
For example, the attack-point rhythm of a the opening phrase
of a piece refers to the abstract temporal relationships
among the individual pitches of the melody. In contrast to
rhythm, attack-point rhythm considers the
temporal distance between events rather than the flow of musical energy
occurring between them. See Graybill (1990).
