As an organ recitalist, Dr Jackson has travelled widely, both in this country and abroad. He has composed extensively for the organ and his musical output also includes an organ concerto, a symphony, an overture, two monodramas, and much choral music. The double-choir anthem Alleluia, laudate pueri Dominum was composed in October 1971 for Andrew Carter and the Chapter House Choir at York.
Following the opening rhythmic fanfare, the syllables of 'alleluia' are split up and sung by each of the voices in turn; this device is used in a number of different ways throughout the work. There are also dramatic key changes and a simple but energetic melody is used for the words 'laudate nomen Domini'. This melody is passed through the voices, gathering strength before its final triumphal appearance towards the end of the anthem.
