The assignment to write a test piece for the National Brass Band Championships ended up also being a 'test piece' for myself as a composer. Although being quite familiar with the Brass Band phenomenon, as a composer I still have the feeling of being an outsider. Delta Energy turned out to be a non-program composition. The Brass Band as orchestra form is depicted musically in this piece. All the specific characteristics are portrayed in varying settings. Solo passages for Euphonium, Flugelhorn and Cornet alternating with extensive tutti-passages and of course technical highlights form the ingredients for this work written in rhapsodic form. The title "Delta Energy" is derived from a project of the N.V. Nederlandse Gasunie in Groningen which also contributed in making this composition possible. 12:00
