Antumbra

composition
posted on 2023-07-13, 23:42 authored by Melody EotvosMelody Eotvos

The antumbra (from Latin ante, "before") is the region from which an occluding body appears entirely within the disc of a light source. Most often associated with the sun and moon, an observer in the antumbra region would experience an annular eclipse, in which a bright ring is visible around the eclipsing body. If the observer moves closer to the light source, the apparent size of the occluding body increases until it causes a full umbra.

The three movements (I - Suspended, II - Canon, III - Time) of this composition are a play on this phenomena, where the percussionists part mostly functions as an occluding body and the electronic track drifts and projects around the acoustic percussion like a light source responding to a solid object.
