Equilibrium was composed for Bandmaster Ross Johnson and Camberwell Citadel Band of The Salvation Army. The title suggests a state or situation in which opposing forces or factors balance each other out and stability is attained.

Equilibrium is based around the hymn tune St Margaret which can be found in its original form acting as the central balance point in the music. The work on the whole is developed from this hymn tune with fragments of the melodic line and developing material scattered around the central section. This gives an end product which is a musical balance of ideas gathered either side of the original material.
