Aequale

From Wikipedia, the free encyclopedia

Aequale (from voces aequales, equal voices or parts) is a musical idiom. The aequale has become established as a generic term for short, chordal, three or four part trombone pieces. Old church music regulations from Linz show that such pieces were used at funeral services in Austria. The performance of such pieces from towers on All Souls' Day and the previous evening has an association with the funeral service. The theological meaning of the trombone as a symbol of divine presence, the voice of the angels and instrument of judgement is thereby underscored.^[1]
