21st Century (2006). Okukoowoola was premiered at the 2006 IHS in Cape Town, South Africa. An unaccompanied horn call by one of Africa's leading composers, it adds unique diversity to the solo horn repertoire and is suitable for professional and advancedstudent hornists. Based on the traditional Kiganda pentatonic music of Uganda, Tamusuza uses many unusual extended techniques in order to make the modern horn achieve the sounds and inflections of African vocal and percussion music: eggono note bends, quartertones, harmonics (played with tuning slides removed), African ostinatos and drumming effects with the mute. Short, colorful and visually dramatic. Featured in the February 2007 edition of The Horn Call.
