Bert Appermont The Green Hill, for C:Bb Baritone, Euphonium and Band. Concert Band Full Score. This piece was commissioned by Swiss euphonium virtuoso Eich Schmidli. Bert Appermont dug deep into Celtic music for inspiration and created a fantasy that shows off the incredible, but often over- looked, veratility of the euphonium. Charming lyrical melodies, virtuosic runs and exciting, colourful tuttis create plenty of contrast in this exciting work.
