Barbara Barry observes that there are different interpretations of musical time, based around measurement and experience. The clocked measurement of time is here distinguished from the natural time of sun and moon movement, and biological experience.
Alternative interpretations are different kinds of measurement or quantification of time, taken from the standpoint either of experiential consciousness – through awareness of changes in external events or internal changes of state – which is dynamic model (empirical), or by reference to an objective standard, such as clock time, which is a static one (formal schemes of measurement). Almost any temporal event can be explained by one kind of direction in terms of the other; that is, an event as experience can be checked against clock time, or the other way around, a given duration can be used as the limits within which certain events take place. Any abstract (non-interpreted) duration can be matched against any of the four types of explanation, according to content, frame of reference and initial standpoint. For example, two hours as a typical sub-span in an individual’s life can constitute part of biological time (formal/analytic): as time marked by natural time-keepers (movement of the sun and moon) it is cosmological time (formal/synthetic): and as time as creative thought or enjoying works of art it is aesthetic time (empirical/synthetic)…
For music the term “experiential” seems preferable to “synthetic” because it clarifies the two basic standpoints of musical time, as either objective investigation or continuous experience. In analytic musical time the work is regarded as object, in order to demonstrate its components and relationships by means of an analytic method or procedure which interprets the work’s organization usually from one point (or possibly two points) of view – for example, motivic construction, serial organization, rhythmic structure, pitch classes and set theory aggregates. The converse of this, experiential musical time, considers a work as musical/temporal experience; it is concerned with how inherent and individual factors are inter-related, what factors contribute to affective response, and how musical time passes (Barry 1990, 84-86).
