From his experience as a conductor and adjudicator, Bert Appermont knows that bands often experience the same problems: lack of sound control, intonation difficulties, uncontrolled articulation and insufficient phrasing. Practising these aspects is very demanding and there is little material available that is also enjoyable to play. Four Original Warm-Upsconsists of four fun warm-up pieces. Each piece focuses on one of the problems without the music being dull. The four pieces work equally well when played together or as individual items either at rehearsals or in a concert.
