Tony Osborne . Written in 1981 for the composer's own pupils, these two short pieces are in a fun, melodic and accessible style. Popular at music courses and concerts, they are a useful introduction to double bass chamber music and are easy on the ear. There are few technical challenges but much scope for great music making. Playable with bass to a part or larger forces, these trios are typical of the effective and idiomatic music written by Tony Osborne, one of the most successful composers writing for the double bass today..
