Here's a short work by an Australian composer, played by an Australian organist - though not on an Australian organ.
Rosalie Bonighton (1946 - 2011) was a highly respected composer who specialised in contemporary church music. Her compositional style was influenced on the one hand by plainchant and Celtic folk song, yet on the other hand by the extended harmonic tensions of German romanticism, multi-rhythms, jazz harmonies and syncopation. Her works were commissioned by - among others - the Royal School of Church Music (Australia), the Australian Music Examinations Board, the National Liturgical Music Convention, and by the university in her home town of Ballarat, Victoria. She also composed works aimed at parish organists. She worked as a school organist, parish organist/music director and as a piano accompanist.
This short work for solo reed appeared in a Kevin Mayhew publication called "Couple The Tuba (Manuals)", published in 2004.
It is written on 2 staves, and I played it using manuals only. Using the Master Couplers in Hauptwerk I added a Pedal Bass to Great coupler to the Salisbury sample set. The wonderful Willis Tuba has plenty to say!
